US regulators plan to require airlines to inspect some 2,200 Boeing 737s and 757s due to a risk that improper maintenance could have jeopardized the integrity of the jets’ main landing gears.
The Federal Aviation Administration (FAA) on 7 July issued a proposed rule addressing the concern, which became evident following the collapse of a 767’s main landing gear.
The 767 incident occurred after workers improperly used a grinder to “machine the inner diameter” of the jet’s main landing gear outer cylinders, causing heat damage, the FAA says.
