Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 series airplanes. This proposed AD was prompted by a report of a crack found in the frame during a structural inspection of an airplane equipped with an Air Cargo Equipment (ACE) cargo loading system in the forward cargo bay. This proposed AD would require an inspection or maintenance records check of certain frames for any repair and applicable on-condition actions, and a repetitive high frequency eddy current (HFEC) surface inspection of certain frames for any crack and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
