Airworthiness Directive · Amendment 39-21266 · Fuselage
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 757-200, -200CB, and -300 series airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2018-06- 07, which applied to certain The Boeing Company Model 757-200, -200CB, and -300 series airplanes. AD 2018-06-07 required inspecting the fuselage frame at a certain station for existing repairs, repetitive inspections, and applicable repairs. This AD requires the actions in AD 2018-06-07, with an expanded inspection area, additional inspections, a modified inspection type, and applicable repairs. This AD was prompted by a report of fatigue cracking found in the fuselage frame at a certain station, which severed the inner chord and web. The FAA is issuing this AD to address the unsafe condition on these products.
