Summary

We propose to adopt a new airworthiness directive (AD) for Leonardo S.p.A. (Type Certificate Previously Held by Finmeccanica S.p.A., AgustaWestland S.p.A.) Model AW139 helicopters. This proposed AD would require inspecting and altering the number 1 driveshaft (driveshaft). This proposed AD is prompted by reports of scratches that were found on the driveshaft. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
