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 鈥渇lap synchro wire鈥 missed by the autothrottle computer, which manages the plane鈥檚 thrust, 鈥渃ould result in loss of control of the airplane,鈥 it said.

An interim report from Indonesian investigators in February said the doomed jet鈥檚 throttles showed an 鈥渁nomaly,鈥 though it said the cause of the crash was unclear.

鈥淭he 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,鈥 the FAA said.

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