Airworthiness Directives; The Boeing Company Airplanes

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