Full official abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all de Havilland Model DHC-7 series airplanes, that currently requires certain structural inspections, and repair, if necessary. This amendment requires an additional structural inspection. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct fatigue cracking in certain significant structural areas, which could reduce the structural integrity of these airplanes.
