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

This amendment adopts a new airworthiness directive (AD) that is applicable to all Lockheed Model L-1011-385 series airplanes. This action requires inspections to detect cracking or severing of the fuselage frames, and an additional inspection or repair, if necessary. This amendment is prompted by reports indicating that fatigue cracking was found on certain fuselage frames on these airplanes. The actions specified in this AD are intended to prevent reduced structural integrity of the fuselage shell due to the problems associated with fatigue cracking.
