## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing 777 series airplanes, that requires a one- time inspection to detect cracking of the fastener holes common to the upper wing skins and trailing edge panels of both wings, and corrective actions, if necessary. This amendment also requires coldwork of the fastener holes and installation of new or serviceable fasteners. This amendment is prompted by a report indicating that fatigue cracks have been found in the upper wing skin of both wings. The actions specified by this AD are intended to prevent fatigue cracking of the upper wing skin, which could result in reduced structural integrity of the wing.
