Airbus will launch a re-engined version of its A320 family aircraft Wednesday, for entry into service in 2016, say industry sources.

The A320 NEO (new engine option) will be launched with variants of Pratt & Whitney's PW1000G and CFM Leap-X engines.

The 150-seat A320, the original member of the European airframer's narrowbody family, will be the first model offered with the new engine option.
Just out from Boeing:
Boeing has readied ZA002, the 787 flight test airplane that experienced an electrical fire on Nov. 9, to be flown from Laredo, Texas, to Seattle. Maintenance technicians replaced the damaged P100 power distribution panel, repaired damage to interior composite structure and installed new insulation material.

The team in Laredo, Texas, has completed a series of ground test operations and inspections to validate the repairs. The flight, which is expected to occur soon, will not include test operations.
Boeing says ZA002 will ferry to Boeing Field, joining ZA001, ZA003, ZA005 and ZA006. ZA004 flew to Everett for maintenance operations on November 21. ZA002 is scheduled to depart Laredo at 2 PM local time for a return to Boeing Field at 4:24 PM PST, though departure, enroute and arrival times tend to vary greatly.

In other 787 production news, JA822J, the third aircraft for JAL was fitted with its twin General Electric GEnx-1B engines. This will make it the first production 787 with GE engines.

The fitting provides a good indication of the potential delivery order for the early aircraft, with program sources saying Airplane 23 will likely be the third or fourth production aircraft to fly in with the pack of Airplanes Seven, Eight and Nine for ANA. The aircraft's destination: Lackland Air Force Base for activation of Boeing's 787 change incorporation and refurbishment operation in San Antonio, Texas.

Though, production flights are farther down a short but non-negotiable to-do list for Boeing, which first has to establish a new schedule for the program while designing, validating and implementing its electrical system software and hardware changes, while satisfying the FAA that the 787 test fleet can return to flight operations.

"We have another several weeks of work to do to get the fix in place," Boeing Commercial Airplanes CEO Jim Albaugh told Reuters today. "Once we understand the fix, we'll be able to tell you what the impact on the schedule."
First day back at my desk in DC since November 12 following China and Thanksgiving, and I'm a bit slow getting back up to speed today, but wanted to share some Monday news items to chew on:

ANA says 787 delays are "a great disappointment" and the carrier is "pushing" Boeing to "present the detailed cause of the irregularities" resulting from the November 9, ZA002 fire, while China Eastern is considering canceling its order for 15 787s over the delays, which are estimated to stretch another six months.

Meanwhile, A350 supplier Aerolia plans to begin production of the composite nose panels and shells for MSN001 on Tuesday after Spirit AeroSystems made its first 64ft 6in Section 15 crown panel in North Carolina last week. Delivery of the first production aircraft is now slated for the second half of 2013. Meanwhile in Sydney, the Qantas A380 fleet is returning to service again, gradually.

On the engine front, CSeries' PW1524G powerplant has passed 80h of testing, and Pratt & Whitney says: "We have not uncovered anything that tells us we need a major design or architecture change." Though Qatar Airways CEO Akbar Al Baker has cooled again to CSeries, just as SAS says it's the leading contender for a 55-aircraft order.

On the business jet side of things heading for the Middle Eastern Business Aviation show in Dubai next week, it looks like landing gear supplier Heroux-Devtek has won a contract for a Dassault business jet that Dassault whose existence the airframer has not yet announced.

Over on the new content side of things, here's an up close look at the ARJ21 from Zhuhai:

Boeing says its first 787 delivery will slide due to software and minor hardware changes to the electrical system, an assessment the company says will be completed within "the next few weeks."

The airframer needs to implement changes to the software that manages and protect power distribution on the aircraft, as well as a minor hardware change to the P100 distribution panel to prevent foreign object debris (FOD) ingestion.

"We have successfully simulated key aspects of the on-board event in our laboratory and are moving forward with developing design fixes," says 787 vice president and general manager Scott Fancher

Boeing says foreign debris "most likely" caused the November 9 fire aboard ZA002 that has halted 787 certification operations.

The company adds that "engineers have determined the fault began as either a short circuit or an electrical arc in the P100 power distribution panel" which sits against the left wall of the 787's aft electronic equipment bay and manages power generated by the aircraft's left engine.

Randy Tinseth, Boeing vice president of marketing, says: "Whatever this foreign debris was, it wasn't something big - such as a tool - it was probably something small. We're taking the right steps to ensure the power distribution panels are better protected against foreign debris."

Boeing says it remains unsure how the FOD got into the P100 panel in the first place, and could have been in the panel for sometime, though the company concedes it won't know how it got there.

As for the six grounded flight test aircraft, Boeing has not yet determined whether or not the design changes would have to be implemented before resuming certification activities, saying only: "Boeing is developing a plan to enable a return to 787 flight test activities and will present it to the US Federal Aviation Administration (FAA) as soon as it is complete."

In the interim, Boeing will continue ground testing the fleet and may ferry ZA003 from Everett to Boeing Field in the near future.

Boeing says it is now "assessing the time required to complete the design changes and software updates that are being developed."

In the 15 days since ZA002, Boeing's second of six 787 flight test aircraft, suffered a fire in its aft electrical equipment bay, forcing a fleet-wide halt in certification testing, the airframer is days, if not hours, away from releasing its findings of its investigation and disclosing the impact to the aircraft's first delivery, say company and industry sources.

An additional delay to the 787's entry into service with All Nippon Airways is now a virtual certainty, the length of that delay, however, is yet unknown.

While some analysts have suggested the 787's first delivery could slip to 2012, an additional delay of more than nine months, Boeing's previous six delays have never shifted the schedule more than six months at a time. A six month slide beyond today's February 2011 plan would place handover to ANA around August of 2011, more than three years after its original target.

Equally important in establishing the root cause of the fire, reported to be foreign object debris (FOD) that caused a short in the panel, is ensuring primary electrical system redundancy remains intact if such an incident were to reoccur. One program source indicates FOD clogging an air duct that cools the P100 panel may be a culprit.

The Seattle Times, citing a source close to the program, reported the 787 fleet, including 23 production aircraft in Everett, have been searched for FOD.

Though the fire, which happened while on approach to Laredo, Texas, and its root cause, revealed an Achillies heel in the 787's electrical system that must be resolved before the Dreamliner can enter service.

In an internal message to program employees last week, Scott Fancher, 787 program manager and general manager said "we have made good progress in replicating the effects in our integration labs".

While the specific "effects" have not been disclosed, under normal operation, a drop out of the P100 panel, feeding electricity from the left engine's twin variable frequency starter generators (VSFG) to aircraft systems, should have compensated by prioritizing the flow of electricity from the right VSFGs into the healthy P200 panel for distribution. Instead, the fire caused 787 to perceive it had lost electrical power completely, causing the Hamilton Sundstrand-built ram air turbine (RAT) to deploy.

The RAT supplies just 10 kVA of electricity, a fraction of the up to 1.45 megawatts of power generated by the aircraft's primary systems, including the APS-5000 auxiliary power unit (APU). Sources familiar with the incident say the APU, which supplies power to the P150 power distribution panel, was not running at the time of the fire.

The result, was the loss of four of five, heads down displays (HDD) and the twin heads up displays (HUD), as well as autothrottle control and a "cascading" series of failures.

However, Boeing concluded that with its twin Trent 1000 engines still running, ZA002 was "in a configuration that could have been sustained for the time required to return to an airport suitable for landing from any point in a typical 787 mission profile," a defense of the 2008 Federal Aviation Administration's special condition imposed on the aircraft's electrical system, as well as its sought-after extended twin engine operations (ETOPS) certification.

Since their November 9 grounding, Boeing has received permission from the FAA to relocate three 787s. ZA001 and ZA005 returned to Boeing Field from remote testing in South Dakota and California, respectively, and ZA004 was ferried to the company's Everett facility for maintenance.

Fancher added "re-positioning these airplanes back to Seattle will better prepare us for any modification that are needed as a result of this event."

The extent of those modifications is another unknown and covers a wide spectrum of possibilities from a limited software modification all the way to complete redesign of the more-electric systems architecture of the 787.

At its inception, the Boeing used the 787 to push the outer envelope aerospace manufacturing, materials and systems, the three attributes that define an aircraft's development.

The airframer had encountered great pain with the 787's globally distributed supply chain in 2007 and 2008, a composite structural flaw in the aircraft's side-of-body in 2009, and now in 2010 a potentially significant change to the aircraft's electrical system.

Late discovery of design changes following treacherous incidents is not new to Boeing commercial development programs. 

Nearly 28 years to the day earlier, the third of five 757 flight test aircraft suffered severe engine damage during a natural ice build up test on its Rolls-Royce RB211 engines, 

An FAA representative onboard the aircraft, which was also being co-piloted by an FAA pilot, said at the time of the incident remarked: "We almost lost one."

The incident prompted a late design change engine that was not validated by the FAA until nearly the last minutes before the type was handed over to Eastern Airlines in late 1982, followed by its January 1983 entry into service. 


HONG KONG -- In an customer memorandum dated Wednesday, November 17, Airbus's Toulouse-based Flight Safety Department issued an incremental update to its findings on Qantas Flight 32. The brief memo is a clear, if not directly stated, defense of the A380's redundancy following the QF32 investigation into the uncontained failure of the aircraft's number two Trent 900 engine.

The report also adds additional technical color on the state of the aircraft after the engine failure and its publication comes a day after other internal Airbus reports were leaked illustrating the extent of the damage sustained by VH-OQA.
A380 / RR TRENT 900 - QANTAS VH-OQA INCIDENT ON 4th NOVEMBER 2010.

FROM : AIRBUS FLIGHT SAFETY DEPARTMENT TOULOUSE

Subject: A380 / RR Trent 900 - Qantas VH-OQA incident on 4th November 2010

Our ref.: QF32 AIT 3, dated 17th November 2010


This AIT is an update of the AIT 2 following the in-flight engine failure during flight QF32 from Singapore to Sydney, on 4th November 2010.

This AIT has been approved for release by the Australian Transport Safety Bureau (ATSB) who leads the on-going ICAO Annex 13 investigation.

The second RR inspection program applicable to the Trent 900 engine family and covered by EASA Engine Airworthiness Directive has been published allowing continuous operations of the fleet. Together with its partners, Airbus is providing support to the operators for engine logistics to minimize interruptions to the fleet.

One single high energy fragment is considered from a certification requirement viewpoint. The damage assessment has established that the IPT disk released 3 different high energy fragments, resulting in some structural and systems damage, with associated ECAM warnings. Therefore the crew had to manage a dynamic situation.

Despite the situation, amongst the various available systems supporting the crew to operate the aircraft and return safely to Singapore were:

- Flaps remained available (slats were jammed retracted).

- All flight control surfaces remained available on the pitch and yaw axis.

- The roll control was ensured through: (a) on the left wing: inner aileron, spoilers 1, 3, 5 and 7; (b) on the right wing: mid and inner ailerons, spoilers 1, 3, 5, 6 and 7.

- The flight control laws reverted to Alternate law due to the loss of the slats and of some roll control surfaces. Normal law was kept on longitudinal and lateral axes.

- Flight envelope protections were still active.

- The autopilot was kept engaged till about 700 feet Radio Altimeter, time at which the crew took over manually. Flight Directors were ON.

- Manual control of engines 1, 3 & 4 was maintained till aircraft stop.

- Landing in SIN took place about 1 hour 40 minutes after the engine 2 failure with flaps in
configuration 3.

- Normal braking was available on both body landing gears with antiskid, and alternate braking without antiskid on both wing landing gears. The crew modulated braking in order to stop close to emergency services.

- After the aircraft came to a stop, the reason engine 1 could not be shut down has been determined: 2 segregated wiring routes were cut by 2 out of the 3 individual disk debris.

Airbus continues to work in support of the on-going investigation to complete the detailed analysis.

An update to operators will be provided as soon as further consolidated information is available.
page-5-600x422.jpgAustralian reporter Ben Sandilands has published an extraordinary visual and technical account of the damage sustained by VH-OQA when its number two Rolls-Royce Trent 900 engine suffered an uncontained failure on November 4 six minutes after takeoff from Singapore's Changi International Airport. Sandilands' report originates from the preliminary Airbus assessment for the Australian Transportation Safety Bureau (ATSB) investigation into incident aboard Qantas Flight 32.

The document's authenticity has been confirmed by Airbus.

The explosion, now traced to an excessive oil build up in the intermediate and high pressure turbines of the Trent 900 engine, caused engine debris to be violently expelled into the surrounding structure of the A380.

Airbus has grouped the damage to VH-OQA in several main areas, including to "perforations" to the aircraft's wing, which entered in the bottom skin of the wing and exited the upper skin. Additionally, two additional perforations were sustained to the lower panel of the wing, as well as the belly fairing and inboard flap track fairings.

damage-5-596x450.jpgThe first, and larger, of two major punctures was suffered by the droop nose 2 on the wing's leading edge structure. In the line of fire was the drive motor for the droop nose which was "badly damaged" and "seems ot [sic] have been on the direct path of trajectory through the wing." The debris entered in front of wing rib 13 on the lower panel and exited at the topskin just in front of rib 12.
 
The second major puncture came as engine debris tore into the lower side of the droop nose panel, and continued its path through the front wing spar (CATIA rendering pictured above). As the debris transited the A380's wing structure, a fuel pipe and wiring were severed near wing rib 9 where it exited.

Additionally, the lower skin on wing panel 1 was punctured in two locations, causing a leak in the A380's left wing inner tank. The first, was at rib 7 at stringer 0 and the second at rib 10 and stringer 6.

The result of the punctured fuel tank was a steadily increasing imbalance in the aircraft's center of gravity as the left wing tank emptied its contents over Batam Island.

Immediately following the explosion in the number two engine, the crew was presented with 53 electronic centralized aircraft monitor (ECAM) messages, including the confirmed failure of the A380's green hydraulic system. The severed wiring also appears to have locked out control of engine number one to the crew.

Sandilands addresses the questions of the A380's system redundancy directly, writing:
"The wing of the jet shows remarkable structural strength in sustaining damage that might have destroyed the airliners of earlier decades, but the questions as to whether control system revisions are necessary to deal with some of the consequences in terms of failed hydraulics and fuel imbalance are said to be very actively under consideration."
The ATSB plans to release its preliminary factual report on December 3.

ZHUHAI -- Few companies on the planet are as disciplined as Boeing with their words, so how the US airframer chooses to express itself can illuminate how the company's leadership is thinking. Boeing released its third statement Tuesday on the November 9 fire that occurred while ZA002 was on approach to Laredo, Texas. The most important line in the statement at first pass is positive for the 787, taking a glass-half full approach to system redundancy.
"The incident demonstrated many aspects of the safety and redundancy in the 787 design, which ensure that if events such as these occur, the airplane can continue safe flight and landing".
Morgan Stanley aerospace research analyst, Heidi Wood, reads between the lines, remarking:
"The vagueness alerts us, as it sidesteps claiming the systems all worked. This tells us the multiple redundancies may not have performed as they should have, which dovetails with what our sources have been asserting. We're impressed by the honest admission; we believe this is an FAA chief concern. "
Exactly what redundancy was not provided after the P100 panel failed is unclear at this point, but Wood does not expect the flight test fleet to return to testing anytime soon, estimating a December or January resumption of the certification campaign, which "could push first delivery to 2012" with changes to aircraft hardware and software.

ZHUHAI -- With six 737s with Boeing's new Sky Interior now handed over to airlines, the airframer is looking ahead to what's next and may be turning its attention to updating the narrowbody's front office.

With a re-engining decision pushed out following a tepid response from its customer base, Boeing is examining a host of incremental improvements to the 737 as it ups its output over the next three years.

"We think we can incremental improvements that keep us competitive with even an A320 re-engine and it might be something we'd have to do as a combination of passenger appeal, flight deck, as well as weight and fuel efficiency improvements," says Beverly Wyse, 737 program vice president and general manager.

General Electric Aviation provided a glimpse into the possible future of the business end of the 737, bringing a mockup to Airshow China of an updated 737 Next Generation flight deck that consolidates today's six 7in liquid crystal displays into three large 787-style 15.4in panels for improved surveillance, communications and situational awareness.

Under the GE plan, the primary flight and navigation displays would be consolidated into the outboard screens while the Common Display System would become more of an Engine Indication and Crew Alerting system (EICAS) combined with an electronic checklist on the center display.

While the GE Aviation mockup features a side-stick controller, the company acknowledge that it took creative liberties on this point and fully expects the Boeing yoke to remain.

John Hamilton, 737 chief engineer, says a new 737 flight deck may be an attractive option that could be done with little transition time for pilots. Additionally, Hamilton sees a maintenance cost benefit by consolidating the number of parts and spares required for the flight deck.

Though, Hamilton says a new flight deck for the 737 isn't a sure thing: "Does it make sense to bring in a large display for the flight deck? That's is one the things we'll take a look at."

Southwest Airlines has already elected to add two outboard 15.4in glass displays to their 737-300 fleet for the carrier's RNP transition. A GE Aviation representative said the center screen was not selected to save cost on the fleet retrofit. The first example is expected to enter service early next year.

Boeing was selected by Southwest as lead integrator on the project, and could leave open the door for a possible dual application by the airframer for a line-fit option on its 737s.

ZHUHAI -- Rolls-Royce, beset by criticism over its public handling of the uncontained failures of its Trent 900 and 1000 engines, has canceled its planned Airshow China show briefing.

The engine-maker offered no explanation for the cancellation, leaving media attending the show only to speculate on its sudden change of plans.


ZHUHAI -- It's very late here in China at the moment. Wanted to do a very quick post on ZA001 and ZA005 heading home to Boeing Field from Rapid City, South Dakota and Victorville, California, respectively. Following the ferry flights to BFI, the fleet will remain grounded. Flightglobal has the latest details on the ZA002 fire investigation.

ZHUHAI -- At a briefing and announcement at Air Show China Tuesday morning, Comac announced an order for 100 narrowbody C919 aircraft to Air China, China Southern, China Eastern, Hainan Airlines, CBD Leasing and GECAS.

While foreign journalists were banned from the event hosted by state-owned aircraft maker Comac, a side door was left ajar prior to the commencement of the event. Though it was staffed with a police officer, some journalists, includling this one, were provided an unobstructed view of a marketing film for the C919 produced by Comac. Most notably was the presentation of the latest specifications of the new aircraft, but also featured six models that are planned.

These models included the single-class 168-seat (156-seat two class) baseline model, as well as stretched, shrunken, freighter, business configuration and "special" variants. With these plans revealed, Comac's six models appear to be readying for competition against Boeing's 737-700, -700C, -900ER, BBJ and Airbus A319, A321, A320P2F and ACJ.



Air India's first 787 Dreamliner, registered VT-ANA, has been moved from the paint hangar to the Everett flight line. Airplane 25 is slated for a second quarter 2011 delivery to the Indian flag carrier.

C919-launchcustomers.JPG

ZHUHAI -- Comac's C919 narrowbody is set for its mega debut here at Air Show China with orders from six launch customers, including GE Capital Aviation Services (GECAS).

While the total size of the order has not yet been disclosed, Air China, China Eastern, China Southern, Hainan Airlines, Chinese lessor CLC and GECAS are lined up to be the first customers for the 160-seat, CFM Leap-X-powered jetliner.

China's domestic market is forecast to be the fastest growth market on the planet with 7.9% year-over-year average growth between 2009 and 2029, according to Boeing. Seventy-one percent, or 3,090 of the 4,330 aircraft needed in China over the next two decades are estimated to be narrowbodies supporting the intra-China market.

An official announcement is expected at 10:30 AM local time here in Southern Eastern China.

SAN FRANCISCO -- I'm heading West...to go East. After a 5hr hop this afternoon to San Francisco, I'm picking up this Singapore Airlines 777-300ER (Flight 1) for a 14hr 30m flight to Hong Kong for Air Show China in Zhuhai. This aircraft, 9V-SWT, was handed over to SIA at the beginning of 2009 and was the 759th 777 built in Everett. It will be Monday morning by the time I arrive at Chek Lap Kok and then on to nearby Zhuhai by water shuttle.

This week will undoubtedly prove to be one for the aviation history books with the first order for the Comac C919, while it may be ceremonial, the order represents a significant step for China's ascent as a commercial aerospace aspirant. We can only hope this week will bring additional technical clarity about the aircraft as well, despite being six years from its entry into service. I'll have much more on the C919 and ARJ21 as the week unfolds. Next stop, China.


An FAA pilot was flying ZA002 at the time of the aircraft's emergency landing in Laredo, Texas, confirm those with direct knowledge of the incident.

The FAA pilot, whose identity has not been disclosed, was sitting in the left seat of the 787 during its final descent into Laredo. A Boeing Test pilot was sitting in the first officer's seat on the flight deck.

While the FAA pilot performed the landing, on any Boeing experimental aircraft, a Boeing test pilot is considered to be in control and responsible for the oversight of the flight.

Two FAA personnel were part of the crew of 42 aboard ZA002, including the pilot and a systems engineer who was observing in the cabin during the six-plus hour flight to test the aircraft's nitrogen generation system.

At this late stage in the flight test campaign, regulatory personnel are almost always involved in evaluating the aircraft for certification credit.

As the investigation into the fire unfolds and safety and design recommendations are formed, the presence of the FAA pilot and systems engineer on board 787 means regulatory authorities do not have to rely on Boeing's interpretation of events.

During the failure of the P100 power panel, which was first noticed as ZA002 crossed through 1000ft above ground level (AGL), multiple engine indication and crew alerting system (EICAS) messages appeared on flight deck displays before load shedding reduced the available displays to a single screen on the left side of the flight deck. 

A source with direct knowledge of the incident says both heads up displays (HUD) were disabled as well and another says the location of the sole active display ultimately determined which member of the flight crew landed the aircraft.

Evaluating how the aircraft responded to the fire is equally important to regulatory authorities as establishing the cause of the fire in the P100 power panel and Boeing maintains the 787 "performed as expected".

In addition to the eye-witness accounts of those on board the aircraft, Boeing has significant additional data at its disposal to sift through as ZA002 is a fully instrumented flight test aircraft measuring parameters well beyond a normal commercial aircraft.

Boeing continues to inspect ZA002 in Laredo, a process the company says will "take several days" to complete, and adds "it is too early to determine if there is significant damage to any structure or adjacent systems."
Photos have surfaced of ZA002 being worked on in Laredo, Texas after a fire in the aircraft's aft electrical equipment (EE) bay Tuesday crippled the 787 following an emergency landing. The photos, taken by flickr user Stevie.Eliz, were apparently taken yesterday. While the damage to ZA002 was entirely internal, the photos show the deployed ram air turbine (RAT) as well as crews accessing both the forward and rear EE bays.

Meanwhile, ZA001 remains stranded in South Dakota, while ZA005 is in Victorville, California and ZA003, ZA004 and ZA006 are at Everett (3) and Boeing Field (4 & 6). Earlier in the week a Gulfstream G-IV and Bombardier Challenge 600 series business jets made the trip between Boeing Field and Laredo, which was possibly the dispatch of a new P100 panel.







Two days after a fire forced the grounding of the 787 test fleet, a power control panel, responsible for distributing electrical power generated by the aircraft's left engine, is at the center of the investigation.

Program and supplier sources confirm the panel, known as P100, caught fire as ZA002 was passing through 1000ft during its final approach into Laredo, Texas on Tuesday.

Boeing disclosed Wednesday that a power control panel was being replaced, but declined to identify if P100 was the source of the fire.

Boeing declined to comment prior to publication to this report, but later confirmed the P100 panel was significantly damaged by the fire.

Boeing says: "We have determined that a failure in the P100 panel led to a fire involving an insulation blanket. The insulation self-extinguished once the fault in the P100 panel cleared. The P100 panel on ZA002 has been removed and a replacement unit is being shipped to Laredo. The insulation material near the unit also has been removed."

The P100 panel sits on the left side of the aft electrical equipment (EE) bay, and is part of a highly-integrated electrical system that receives 235v ac power from the left engine's twin 250 kVA engine generators for distribution throughout the aircraft.

An identical P200 panel performs the same tasks for the right engine's generators.

The 787 more-electric systems architecture is driven by up to one megawatt of electricity from the two 250 kVA variable frequency starter generators (VFSG) on each of the 787's twin General Electric GEnx-1B or Rolls-Royce Trent 1000 engines. ZA002 is powered by Trent 1000 engines.

The P100 panel is home to seven main components supplied by Hamilton Sundstrand, including those that are responsible for commanding loads on and off to various systems depending on the need on board the aircraft, as well as components that replace thermal circuit breakers, which provide overload and fault protection.

Further complicating ZA002's return to testing is the damage sustained during the fire, which included dripping of molten metal onto the system wiring and internal fuselage structure, which program sources say is driving Boeing's inspection of the area surrounding the P100 panel to "determine if other repairs will be necessary."

"As part of our investigation," says Boeing, "We will conduct a detailed inspection of the panel and insulation material to determine if they enhance our understanding of the incident."

"In addition, we are determining the appropriate steps required to return the rest of the flight test fleet to flying status."

Boeing is continuing to investigate the fire and determine any impact to "the overall program schedule" as it reviews data collected from the incident.
Boeing has grounded it six 787 test aircraft following Tuesday's aft electrical bay fire aboard ZA002.

"We have decided to focus on ground tests while we better understand the incident on ZA002," says Boeing.

UPDATE 1:39 PM ET: Here's my full story on the grounding:
According to a source briefed on the incident, the fire caused a series of cascading failures including drop out of some of the flight deck displays and autothrottle systems.

The extent of damage to the aircraft's systems and composite primary structure has not been officially disclosed by Boeing, but is believed to be extensive, say those familiar with the incident.
UPDATE 2:45 PM ET: A representative from the Laredo Fire Department Airport Unit says upon boarding ZA002 fire fighters found heavy smoke, but no flames, though test personnel told the firefighters that the fire was still ongoing upon landing at Laredo. 

UPDATE 3:34 PM ET: The National Transportation Safety Board is officially "monitoring" the situation in Texas, says Keith Holloway, a spokesman for the board and is "assessing information we are getting" from the FAA. The NTSB adds that no board personnel have been dispatched to Laredo. ZA002 has been moved off of the taxiway to a secure area on the airport. An industry source with direct familiarity of the incident says the FAA, NTSB, Boeing interaction is a bit of a "gray area" as the aircraft is in its development phase.

UPDATE 4:40 PM ET: Did ZA002 lose its Primary Flight Displays? Yes. And No.

A source familiar with the details of the situation said yesterday the pilots lost the primary flight displays while on approach to Laredo. Boeing disputed the claim this morning, saying the pilot did have a PFD on landing. The 787 flight deck allows both to be true. In load shedding situations the outboard displays which are the typical home for the PFDs, enter a reversionary mode and disable the pilot's outboard display and first officer's inboard display. 

On the pilot's PFD, which takes up two-thirds of the outboard screen in normal operations, is shifted to a one-half arrangement on the inboard display and combined with the EICAS display. For the first officer, the outboard display goes to a one-half arrangement with the PFD and ND. While the primary flight display would be lost due to the electrical issue, the PFD would be sustained on the left inboard and right outboard display.

UPDATE 6:06 PM ET: Boeing issues an update on the ZA002 fire. Schedule impact is unknown as the investigation unfolds. 

Initial inspection appears to indicate that a power control panel in the aft electronics bay will need to be replaced on ZA002. We are inspecting the power panel and surrounding area near that panel to determine if other repairs will be necessary.

This is a developing story and will be updated.

Smoke in the cabin of ZA002, Boeing's second 787 flight test aircraft prompted an evacuation of the 30-plus test personnel on board. The test aircraft was enroute to Harlingen, Texas for trials of the aircraft's nitrogen generation system, when smoke was seen in the main cabin. Boeing says ZA002 "continued its approach and landed safely in Laredo, Texas." Adding that the "crew evacuated the airplane safely."

Update 6:57 PM ET: Boeing says ZA002 is on the ground in Laredo, Texas with its evacuation slides deployed. Boeing is "continuing to collect data" on the source of the smoke, which is currently unknown. The FAA says the aircraft landed at 2:54 PM Central Time.

Update 7:30 PM ET: A source familiar with the incident says ZA002 touched down in Laredo after a fire broke out in the aft electronics equipment bay causing the flight deck primary flight displays and auto throttle to fail, additionally the ram air turbine was deployed on landing. The aircraft landed in visual flight rules (VFR) conditions.

ZA002-Laredo.jpegUpdate 8:04 PM ET: Hamilton Sundstrand, which is responsible for the 787's electrical system, says it is in touch with Boeing and is participating in the investigation. A spokesman for the company had no additional details regarding the incident. 

Update 10:56 PM ET: Program sources say all planned flight tests for Wednesday have been postponed until Thursday at the earliest. ZA001, ZA005 and ZA006 have been shifted to ground tests as a result of ZA002's in-flight fire. ZA003 and ZA004 had been previously scheduled to conduct ground testing.

Update 10:08 AM ET: Boeing released some additional details this morning, including the total occupancy of the aircraft, which stood at 42 at the time of the incident. That number is not uncommon when beginning a remote stay as the plane acts as a ferry for test crews. Boeing says "contrary to some reports" the pilot did not lose primary flight displays during the fire, though did not specify if any of the five were inoperative at the time of the fire.

Additionally, programmes sources say ZA002 test crews in Texas are being updated on the status of the aircraft in a briefing this morning.

Five days into the investigation of the uncontained engine failure aboard Qantas Flight 32, several reports have focused attention around oil leaks in the intermediate pressure turbine inside the Rolls-Royce Trent 900 that flies under the wing of the the Australian carrier's A380s. 

The Trent 900s on Qantas's A380s, which are officially known as the Rolls-Royce RB211 Trent 972-84, feature a 72,000lb thrust rating, the higher of two available. Lufthansa and Singapore Airlines selected the 70,000lb rating. The Trent 900 is rated at 76,000 and 80,000lbs of thrust, but both are reserved for the larger A380-900 and A380-800F if/when they begin development.

While the six Qantas A380s remain grounded at this hour, the Australian's Steve Creedy reports that the investigation has focused on Qantas's selection of the 72,000lb thrust rating, for its longest routes.
Engineers believe the higher thrust levels at which the carrier operates its Rolls-Royce Trent 900 engines may result in resonating vibrations that cause oil lines to crack.

The theory has emerged after in-depth inspections uncovered oil in three A380 engines in areas where it should not be present.
...
The Qantas A380 involved, which came into service two years ago, was also used for the trans-Pacific story. The oil leaks in the three engines, found in the intermediate pressure turbine area housing a disc similar to the one that disintegrated in last week's spectacular mid-air drama, caused spotting and pooling that had the potential to spark damaging fires in the engine.
The hunt is on for the second part of the missing turbine gear, believed to be somewhere on Batam Island in Indonesia. The first part of the geared disk was recovered shortly after the incident last week. David Epstein, Qantas general manager , says of the number two engine: "There doesn't appear to be a disk there at the moment. Virtually that entire area, the intermediate chamber of the engine, has disappeared."

Already grappling with intermediate-pressure turbine and oil build up issues on its Trent 1000, which powers the Boeing 787, Rolls-Royce announced Monday it had definitively determined that the uncontained failures on the 900 and the 1000 were "unconnected". 

T900-A380-ECAM.jpgThe intermediate-pressure turbine, which is part of Rolls-Royce three-shaft engine architecture, is unique among the large commercial transport engines. Competitors Pratt & Whitney and General Electric have a two-shaft architecture. The three-shaft architecture allows each part of the engine's core to spin at an optimized speed. The three shafts, which run concentrically, host the low, intermediate and high pressure elements.

The intermediate pressure (IP) compressor and turbine, which are hosted on the same shaft, are allowed to rotate faster than the fan, requiring fewer stages. The result is a shorter and lighter engine.

The Trent 900 architecture features a 116in front fan, which acts as the engine's single-stage low pressure (LP) compressor, followed by an eight-stage IP compressor, six-stage high-pressure (HP) compressor, single annular tiled combustor with 20 fuel injectors, single-state high pressure turbine (drives the HP compressor), single-stage IP turbine (drives the IP compressor) and a five stage LP turbine (drives the front fan).

During its 90th birthday celebration this past weekend, Qantas displayed one of its grounded A380s along with past and present members of the carrier's fleet. Along with an A330 and 747-400, Airbus cracked open the cowl of the Trent 900 on the A380 providing visitors an up-close view of the engine that was busy making less-positive headlines around the globe.

During this same period, Rolls-Royce issued a Trent 900 service bulletin, NMSB72-G589, whose contents is currently unknown, but it is believed to establish the inspection guidelines for the Qantas, Singapore and Lufthansa fleets. No one outside Airbus, Rolls-Royce, regulatory authorities and operators have seen this document.

While Singapore and Lufthansa A380 fleets operate unincumbered right now, Qantas believes its fleet could return to service in no less than 72-hours (Thursday evening local time), undoubtedly under the close watch of Airbus, Qantas, Rolls-Royce and the traveling public.
SEATTLE -- Operating as Giant 4151 late Friday afternoon, one of Boeing's four modified 747-400 Dreamlifters operated by Atlas Air touched down at Paine Field in Everett, Washington carrying a set of wings for the 31st 787, marking the restart of structural deliveries following a two week halt. 

The wings, built at Mitsubishi Heavy Industries' Oye facility in Nagoya, Japan, were flown from Chubu Centrair Airport to Everett with an intermediate tech stop in Anchorage, Alaska. 

The arrival of the wings for Airplane 31 comes one day after the 787 line advanced, making way for the loading of the structural sections for Airplane 29, an aircraft that will eventually be delivered to Japan's All Nippon Airways. 

The advancement of aircraft on the line marks the first time in just over a month the line has moved forward.

Boeing announced October 25 it halted deliveries after the airframer determined it would opt to prevent any workmanship issues with the 30th Alenia-built horizontal stabilizer from traveling to final assembly. The forward and aft fuselages and wings for Airplane 30 arrived the third week of October prior to the delivery halt. 

Yet to arrive in Everett is the horizontal stabilizer for the 30th 787, which is set to be delivered to final assembly ahead of the next line move, scheduled for the middle of November when Airplane 30 will be loaded into position one for the wing and body joins.
Twenty-four hours after the A380's first major incident, a continuing question remains around the state of the aircraft upon touchdown in Singapore and to what extent the aircraft's systems were impacted due to the uncontained failure of engine two. Commercial jetliners for years have been designed with multiple levels of redundancy to endure even the most brutal damage. The A380's safe return to Singapore is further evidence illustrating how the redundancy of aircraft systems provide an extra margin of designed-in safety to commercial air travel.

One video posted by Russia Today (and includes Flightglobal's Cory Matthews footage immediately following the landing of QF32 in Singapore) shows the spoiler operation upon touchdown as filmed from the lower deck of the A380. The video shows only half of the A380's spoilers deployed upon touchdown, further suggesting damage to the Green Hydraulic system following the engine failure. The lack of operation of the wing slats, is consistent with a failure of the Green hydraulic system as well.

Also included below (for a bit of technical background) are three slides from the Airbus Flight Deck and Systems Briefing for Pilots which describes the redundant attributes of the A380's hydraulic system and identifies which flight controls are on which system.

What do we know?
An Airbus A380 VH-OQA operating as Qantas Flight 32 from Singapore to Sydney appears to have suffered an uncontained failure of the second of four Rolls-Royce Trent 900 engines. The flight was operated with 440 passengers and 26 crew on board. The 450-seat aircraft, MSN014, was the first delivered to Qantas in September 2008 following its maiden flight in January of that same year. This particular A380 entered service on October 20 flying Qantas Flight 93 between Mebourne and Los Angeles.

Initial reports first indicated that the A380 had crashed in Indonesia after reports of an explosion followed by debris found on the ground near the island of Batam. Those were quickly confirmed as false upon confirmation from Qantas that the aircraft was dumping fuel and returning to Singapore with an "engine issue." The Australian Transportation Safety Board says the incident occurred around 1:30 PM ESuT and landed at 11:45 AM local time back at Singapore's Changi Airport.

As a result of this incident, Qantas says it has "suspended scheduled A380 takeoffs until sufficient information has been obtained about what occurred on QF32." Airbus and Rolls-Royce have both released statements on the incident, saying they will work closely with investigators to determine the cause of the failure.



ADDITIONAL INFORMATION CONSOLIDATED BELOW THE FOLD

Boeing is once again examining its 787 delivery schedule as it seeks to address the mountain of post-certification rework required to turn partially completed airframes into deliverable passenger aircraft, confirm multiple program sources.

Staff from around Boeing and its supply chain tell FlightBlogger that driving the current schedule review is the formulation of a plan on how to tackle the expansive amount of work required to bring each airframe up to a certified production standard.

Today, Boeing is aiming to hand over its first 787 to Japan's All Nippon Airways in February, just shy of three years since the original May 2008 delivery, though a verdict on the necessary rework is expected in the coming weeks and could impact initial deliveries anywhere from weeks to several months depending on the customer.

"Flight testing is a dynamic process and we constantly review and manage risks and opportunities to the program schedule. Our plan remains first delivery of the Boeing 787 mid-first-quarter 2011," says the airframer.

One program engineer says that in order to meet the mid-February delivery target for ANA all of the design changes for Airplane Seven (JA801A), the first production 787, had to be released by engineering by the close of October, however the source adds "there are some design changes that are not released yet but must be implemented to have the airplane certified" ahead of first delivery.

Program and industry sources suggested Airplane Seven's delivery could be made to ANA on time in February, but how long after it entered revenue service pending additional changes, and how long after that more deliveries followed, remained an open question.

Boeing has remained reluctant to provide guidance on how many 787s it expects to hand over to carriers in 2011, though Jim McNerney, the company's CEO, identified post certification rework a chief priority for the program.

"We are intensely focused on managing the change incorporation process on airplanes already built or in flow," McNerney said in the company's third quarter earnings, which maintained the February first delivery target. "The early delivery schedule is comprised of a mix of airplanes coming off the production line and airplanes completing the change incorporation process."

CSeries-Empennage_560.jpgDuring a visit to Montreal last week, I had an opportunity to discuss the progress of the CSeries with Bombardier vice president of commercial aircraft programs Ben Boehm and we covered a lot of ground in the interview, including the latest on the airframer's sales campaign with Gulf Air, progress on the PW1524G engine, as well as recent current events with Boeing's Alenia-made 787 horizontal stabilizer. Bombardier selected Alenia Aeronautica in March 2009 to design the composite vertical and horizontal stabilizers for the CSeries. Here is the complete transcript of his answer:
Q: Have you been in conversation with Alenia about what specifically has been happening on 787?

A: Yes. Obviously Alenia doesn't reveal to us what's going on with them and Boeing. Our discussions have been more around the aspect that: are you following, our supplier management recipe? Almost in a kind of an auditing sense, we've had a specific meeting with them since those things have become public to say, "Okay, now you understanding, we heard what's happening. We're not going to be rude and try and bug you about that." We're just going to be here and say, "look this is our process, I don't care what Boeing's processes and how they managed you, this is the Bombardier way on how we manage a supplier. And In case you're doubting it and say no we should follow the Boeing way, well no you're going to follow our way, because this is how we started this in 1995 managing off shore design-to-build suppliers."

It includes: You log in and put your schedule in our system. We will have executive program reviews at this frequency. You will supply us burn down plans every month. You will update our weight program at this frequency. And we will be watching you.

Our reputation is staked on you and we're not going to let you mess with us.

The biggest crux of that meeting now that we've heard of the Boeing/Alenia issues is to firmly reestablish our processes, because we know our processes work, ever since the Global [Express] we've been making planes like this with international supply chains so we know it works.

Q: Has Alenia been receptive?

A: The one thing most suppliers have said to us is you know "you're strict, you guys have a different process, but you communicate." And we talk, we meet regularly, we have a process for being able to go back and forth on things.

We can't be draconian and say, "thou shalt do this and thou shalt do that." Because remember why did we pick Alenia? Because they're good at what they do. They make good flight surfaces, in this case the horizontal and vertical stabilizer. We pick specialists in their field.

So when Bombardier picks a supplier, we are picking them for their expertise. That why it's design to build not build-to-print, they are completely responsible.

So, we can't go in there with a big hammer and say, "you're doing it wrong, you're deisgning wrong and all of that" because that defeats the whole purpose. Then it becomes a blame a game, they they could turn around and say, "you told us to do that, so don't blame us".

This way you say, follow our process, meet our goal posts, the rest is up to you. But meet our goal posts and follow the process and that's something Bombardier had to learn, that's taken us years to learn because otherwise you end up in the blame game or you just don't have that relationship.

This week's Movie Monday is a bit shorter than usual, but I thought it was worth sharing the series of short videos Boeing released during the assembly of RC001, the first 747-8I. The clips take you through first wing build up all the way to structural section moves, wing-to-body join, stairwell installation and into final body join and line advancement.

The aircraft moved from the final body join position to the first final assembly slant last week where the aircraft will be powered on and run through a system-by-system checkout before moving to the paint shop and flight line. This, of course, is an over simplification and this process to first flight will take five to six months or so with the maiden sortie penciled in for March.

Building the 747-8I runs in six parts, continuing after the jump. Enjoy.
