Airworthiness Directive · Amendment 39-21909 · Aircraft structures
Leonardo S.p.a. Helicopters
This AD applies to all Leonardo S.p.a. Model AB139 and AW139 helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by the identification of certain parts needing maintenance actions, including life limits and maintenance tasks. This AD requires incorporating into maintenance records requirements (airworthiness limitations), as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, incorporate into maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2), as applicable for your rotorcraft, the requirements (airworthiness limitations) specified in paragraph (1) of European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD 2018-0132, dated June 21, 2018 (EASA AD 2018-0132).
After the action required by paragraph (g) of this AD has been done, no alternative requirements (airworthiness limitations) are allowed unless they are approved as specified in the provisions of the “Ref. Publications” section of EASA AD 2018-0132.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
