## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires replacement of the outboard trunnion pin of the shock strut on the main landing gear (MLG) with a new and improved outboard trunnion pin. 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 prevent failure of the outboard trunnion pin due to fatigue cracking, which could result in collapse of the MLG.
