FAA orders probe of older Boeing jets

The US aviation regulator is ordering Boeing to inspect older generation 737 jets, after the January crash of an aircraft off Indonesia that killed 62 people.

All Boeing 737-300, -400 and -500 planes will need to be examined, a total of 143 aircraft, according to a document from the Federal Aviation Administration. A failure of the “flap synchro wire” missed by the autothrottle computer, which manages the plane’s thrust, “could result in loss of control of the airplane,” it said.

An interim report from Indonesian investigators in February said the doomed jet’s throttles showed an “anomaly,” though it said the cause of the crash was unclear.

“The preliminary data of the ongoing accident investigation shows that it is highly unlikely that the accident resulted from the latent failure of the flap synchro wire,” the FAA said.

But it said the inspection is “necessary to address the identified unsafe condition” that could be found in the planes, which were built in the 1980s and 1990s.
