The FAA, prompted by a NTSB recommendation, is at long last updating decades-old airline maintenance program development guidance that conflicts with similar, newer material.

All Nippon Airways (ANA) and Japan Airlines yesterday conducted inspections of their Boeing 787 fleets after faulty wiring was discovered by ANA in an engine fire extinguisher. ANA discovered improper wiring in the engine fire extinguisher of a 787 during a pre-takeoff inspection, and subsequently found the problem in two more of its 787s.

Almost 20 years into the program, many Boeing 777 parts are still scarce and expensive in aftermarket trading. This may be what the future looks like for other new models that rely on OEMs and long-term agreements for future support. A majority of 777 parts are in short supply, according to Zilvinas Sadauskas, CEO of Locatory.com. “Only 20% of 777 inventories may be found on the open market,” Sadauskas notes. Airframe, component and engine OEMs have maintained tight control of the market. Some engine OEMs buy old engines to secure their position in spares.

Rockwell Collins’ largest acquisition to date—purchasing communications and systems engineering provider, Arinc, for $1.39 billion from the Carlyle Group—will give the avionics maker its own end-to-end communications link between the ground and the flight deck, a connection that is fundamental to the FAA’s Next Generation Air Transportation System (NextGen).

Airframe OEMs are seeing new business opportunities and aftermarket revenue streams for their next generation of commercial jets, but customer support will not be business as usual.

Expect shortage of 777 spares to last at least a couple more years
