A Flightaware alert just went up for BOE 236 this afternoon for takeoff around 1:45pm local time. The significance of this flight is that this is the first flight of the 787 that will undertake the last part of F&R/ETOPs certification testing that is required for FAA type certification of the GE powered 787.
This important testing was partially done by ZA006 a few months ago but FAA requires that some of the tests also needs to be done by a production standard 787. Boeing assigned ZA236, a 787 destined for Air India. The start of the final phase of this testing was delayed and rumor has it that the delay was attributable to lightning protection around the engine pylons for the GEnx-1B engines.
Today's flight should be a standard Boeing checkout flight and there will probably be a couple
More test flights before final F&R/ETOPs flight formally kick off.
Boeing is hoping to start GE/787 deliveries next month so I anticipate that this test should last 3-4 weeks with the aim of first GE powered 787 delivery to JAL at the end of February. However this is all predicated on all testing going well with no major issues being revealed.
