Docket No. 94-NM-225-AD Amendment 39-9115
Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-100 series airplanes. This action requires an inspection to detect discrepancies of the lap joint in certain fuselage stations, repair of any discrepancies, and modification of a certain lap joint. This amendment is prompted by reports of holes in the lap joints and longerons of these airplanes. The actions specified in this AD are intended to prevent reduced fatigue life of the fuselage in the areas in which holes are found.
