GE, Boeing Alert Airlines About 777 Engine Problem

[marmar]

General Electric Co and Boeing Co have alerted airlines about a potential problem with engines on Boeing's long-range 777 jumbo jet that caused the engines to shut in mid-flight twice this year.

The problem affects about 118 so-called transfer gear boxes made between September and March. The part, made by Italian company Avio SpA, are on about 26 in service 777-300ER jets and another 44 aircraft in production, GE said.

There are more than 1,150 of the GE90-115B engines in service and the gearbox has been a reliable part for more than 15 years, GE said. The cause of the problem appears to be with an anomaly in the material that caused gears to separate, although the exact cause remains unknown, GE said.
