The Federal Aviation Administration on Friday ordered airlines to urgently modify engines on Boeing 787 Dreamliners, due to an icing problem that can cause a specific model of GE engine to shut down in flight. The problem affects 176 Dreamliners at 29 airlines, about 44 percent of the worldwide fleet, the FAA said.
The FAA’s airworthiness directive follows a Jan. 29 incident in which one of the two engines on a Japan Airlines (JAL) 787 shut down in midair and couldn’t be restarted. The jet, flying from Vancouver, B.C., with 166 people on board, was about 90 miles from Tokyo’s Narita Airport when the right-hand engine failed.
According to data on that flight provided by aircraft-tracking firm Flightradar24, the pilots landed safely on one engine about half an hour later.
On planes with the same engine model on both wings, the problem could cause a potentially catastrophic dual shutdown of both engines.
The FAA directive says “the potential for common cause failure of both engines in flight is an urgent safety issue.”
The rework ordered by the FAA has already started; GE issued a service bulletin on March 11. GE spokesman Rick Kennedy said rework on about 40 airplanes has been completed.
Airlines have until the first week of October to complete the rework on all their planes. In the meantime, pilots are required to follow a new ice-removal procedure in flight.
