Airworthiness Directives; Boeing Model 767 Series Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767 series airplanes. This proposal would require repetitive inspections of the side load underwing fitting bushings for broken sealant or bushing migration, and corrective action, if necessary. This proposal would also provide optional terminating action in lieu of repetitive inspections. This proposal is prompted by reports of migrated bushings and corrosion on the side load fittings. The actions specified by the proposed AD are intended to prevent corrosion in the side load underwing fitting, which could result in cracking and consequent reduced structural integrity of the wing strut.
