Airworthiness Directives; AgustaWestland S.p.A. (Type Certificate Previously Held by Agusta S.p.A.) Helicopters

Action

Notice of proposed rulemaking (NPRM).

Summary

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