Airworthiness Directives; Lockheed Model L-1011-385 Series Airplanes

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T95-18-52 that was sent previously to all known U.S. owners and operators of Lockheed Model L- 1011-385 airplanes by individual telegrams. This AD requires visual inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, replacement of cracked fittings, and repair of adjacent structure if found to be cracked. This amendment is prompted by reports of cracks found in these fittings. The actions specified by this AD are intended to prevent failure of these fittings due to fatigue cracking; such failure could result in rapid decompression of the airplane during flight.
