Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2019-13047

The FAA proposes 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 reports of cracks in the fuselage frame web at body station (STA) 1640. This proposed AD would require, depending on configuration, a general visual inspection for any previous repair, such as any reinforcing repair or local frame replacement repair, repetitive open hole high frequency eddy current (HFEC) inspections for any crack of the fuselage frame web fastener holes, on the left and right side of the airplane, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
