FAA orders new 787 electrical fix to prevent power failure

All Boeing 787 operators will be required to periodically deactivate the electrical system to avoid a problem with a newly-discovered software bug that could cause the aircraft to lose alternating current (AC) power, the US Federal Aviation Administration says in a new airworthiness directive. The agency adopted the final rule after Boeing reported the results of a laboratory test showing a total loss of power is possible if the generator control units run continuously for eight months, says the… (www.flightglobal.com) עוד...

Boeing expects delamination issue to slow 787 deliveries in the near term

Boeing expects the inspection and repair of 787s affected by composite delamination due to improper longeron shimming to slow near-term deliveries, but is unlikely to change its full year delivery forecast. "We don't think it will impact deliveries for the year, it will slow things down initially though," said Boeing Commercial Airplanes CEO Jim Albaugh at a dual 747-8F and 777F delivery to Korean Air Cargo in Everett, Washington 6 February.

Delamination prompts Boeing to inspect 787 fleet

Boeing again faces a manufacturing quality issue, requiring inspections and repairs of its 787 fleet. Structural stiffeners were found to be improperly joined to the composite skin in the aft sections of the aircraft, causing parts of the aircraft's carbon fibre structure to delaminate, confirms the airframer. "Boeing has found that incorrect shimming was performed on support structure on the aft fuselage on certain airplanes in our facility in Everett, [Washington]," said the… (www.flightglobal.com) עוד...
