## Abstract

We are adopting a new airworthiness directive (AD) for certain AgustaWestland S.p.A. (Agusta) Model AB139 and AW139 helicopters. This AD requires inspecting the nose landing gear (NLG) pin installations for incorrect assembly. This AD is prompted by reports of incorrectly installed pins discovered on in-service aircraft. These actions are intended to detect incorrectly installed pins, which could result in collapse of the NLG during taxi or landing.
