Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes. This proposed AD was prompted by a report that during a maintenance check an operator discovered cracking in the station 1460 frame web and inner chord between certain stringers. This proposed AD would require an inspection of the fuselage frames for any existing repair, repetitive surface high frequency eddy current (HFEC) inspections of the fuselage frames with a cargo liner support channel for any cracking, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
