No split over similar-looking wingtips

In a remarkable coincidence, the split-tip winglet that went out of fashion with the demise of the MD-12 concept in the early 1990s has suddenly re-appeared in in two applications — Boeing’s straight-edged Advanced Technology (AT) winglet for the 737 Max (above) and Aviation Partners’ scimitar-edged split-tip blended winglet on the 737 Next Generation series.

Superjet honeymoon over with launch customer

The relationship between Sukhoi Superjet and launch customer Armavia continues to unravel, as new reports indicate the Armenian flag carrier has returned its only delivered SSJ100 jet. Armavia’s enthusiasm for the Superjet has waned ever since it took delivery. That much was apparent last November. Armavia had operated the 94-seater for seven months, and Sukhoi […]

PICTURE: Alaska apologises for MX message on 737

Photo: Reddit Alaska Airlines says on Twitter this perhaps unfortunate maintenance message, which went viral on reddit this week, was “inappropriate”, and, more ominously, “we have followed up w/ the team”. (Uh-oh.) But there may have been good reasons why the maintenance team wrote a message that some passengers clearly interpreted as unintentionally funny and/or […]

PREVIEW: Big earnings day for Boeing Commercial Airplanes

Boeing Commercial Airplanes (BCA) expects later this morning to post a good second quarter, and we’ll wait for the final tally to decide if we should further modify ‘good’ with ‘very’. It’s the first time that’s possible to say without any major caveats since 2007. With the 787 and 747-8 finally certified amidst swelling demand […]

ANA 787 grounding spotlights Hamilton Sundstrand gearbox

Photo: Rolls-Royce All Nippon Airways has grounded five Boeing 787s powered by Rolls-Royce Trent 1000 engine. Ground endurance tests by R-R showed the engine could be damaged by crown gears that corroded faster than expected. (Click here to read the full story posted earlier this morning by Flightglobal’s Singapore office.) R-R selected Hamilton Sundstrand nearly […]

Mid-wing 747 Wingbox.jpg

Why would Boeing design a mid-wing, twinjet, double-decker 747?

Breguet’s range equation is a cruel tyrant. The fuel-efficiency conscious airframe designer has only three levers — weight, thrust and aerodynamics — to pull, and yanking one often complicates things for the other two. At the concept stage, however, it still helps to tug upon one of Breguet’s levers, just to see what happens. So […]

FARNBOROUGH: Orders ‘race’ winners and losers (w/CHART)

It wasn’t a banner year for the Farnborough air show in terms of orders, by any means. But that’s probably to be expected. After all, how many new orders can Airbus claim for a product — the A320neo family — that does not enter service until 2016 and is practically sold out with more than […]

FARNBOROUGH: Ground support vehicle sparks minor 787 incident

A fuel problem in a ground support vehicle for the Qatar Airways 787 caused a minor scare on the flightline this evening, Boeing says. Emergency crews and vehicles around 17:30 swarmed the brand-new widebody, which was parked near the East Apron just aside the Farnborough runway. Emergency crews were seen removing blackened items lying on […]

FARNBOROUGH: Boeing test pilots narrate, discuss 787 flying display

Boeing’s return to the flying display circuit after a 28-year hiatus provided several crowd-pleasing moments, but that was not originally the airframer’s plan. Boeing actually had intended to show off little more than two sedate fly-pasts. The steep-climbing, 2g banking, touch-and-go routine only evolved because of local restrictions on the 787′s overflight footprint. That’s one […]
