Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200CB, and -300 series airplanes. This proposed AD was prompted by a report of fatigue cracking found in a certain fuselage frame, which severed the inner chord and web. This proposed AD would require inspecting the fuselage frame for existing repairs, repetitive inspections, and applicable repairs. We are proposing this AD to address the unsafe condition on these products.
