FAA gives ETOPS nod to Trent 1000, 787 readies for Package B

Boeing 787 Dreamliner N787BA ZA001

The US Federal Aviation Administration granted extended operations (ETOPS) certification to the Rolls-Royce Trent 1000 (Photos) allowing the engine to be operated 330 minutes from a diversion landing field for a Boeing 787. Meanwhile, ZA004, is parked at Boeing Field and being retrofitted with the latest Trent 1000 ‘Package B’ improvements that will bring specific fuel consumption to within 1% of the originally planned specification.
For Rolls-Royce, the Engine ETOPS certification differs from ETOPS airframe-engine certification (AEC) as the powerplant is given regulatory approval separately from the aircraft and all of its systems for long-range operations. Formal 787 AEC ETOPS testing, which includes system functionality & reliability testing, has not yet begun, though build-up tests were run in April on ZA003. The engine completed its 3,000 cycles ETOPS validation through ground testing back in August 2009.
Also, Boeing confirmed late last week that the test fleet had been fully upgraded to operating the latest electrical system software that was developed following the fire aboard ZA002 in November. The test fleet had been flying with an interim patched version, and ZA006, the last to be fitted with the software dubbed v10.4C, completed the installation in late April.

    This is great news to hear. I know that Boeing was a little worried about being able to get the ETOP cert. and if it would come in time to maintain their delivery schedule.

    Do you know when the GE engine will receive it’s ETOPS cert.?

    “Formal 787 AEC ETOPS testing, which includes system functionality & reliability testing, has not yet begun…”

    Any info on when Boeing expect to start the ETOPS certification process for the 787 and when it is schedule to be granted (if testing is successful)?

    There seems to be a stall in this process!

    Be careful, this ETOPS cert. is for the engine, but NOT for 787!

    Are they going to use Package B for ETOPS certification of the airframe? Would take testing well into August though.
