## Summary

We propose to adopt a new airworthiness directive (AD) for AgustaWestland S.p.A. (AgustaWestland) Model AW189 helicopters. This proposed AD would require inspecting the tail gearbox (TGB) fitting for a crack. This proposed AD is prompted by a report of a crack on a TGB fitting that was found during a scheduled inspection. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
