## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Bombardier Model DHC-8-102, -103, -106, -201, -202, - 301, -311, -314, and -315 series airplanes, that requires revising the Bombardier maintenance program to incorporate repetitive inspections to detect fatigue cracking in certain structures; and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information issued by a foreign airworthiness authority. The actions specified by this AD are intended to ensure that fatigue cracking of certain principal structural elements is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
