Airworthiness Directive · Amendment 39-21768 · Leonardo S.p.a. Helicopters
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AB139 and AW139 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2019-0073, dated March 28, 2019 (EASA AD 2019-0073).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by a report of damage (burns) on the tail rotor blades (TRBs). This AD requires an inspection of each TRB for the general condition and any evidence of burns and replacement if necessary, as specified in a 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.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2019-0073.
(1) Where EASA AD 2019-0073 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2019-0073 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where the service information required by EASA AD 2019-0073 specifies returning a part to the manufacturer, this AD does not include that requirement.
(4) This AD does not require the “Remarks” section of EASA AD 2019-0073.
(5) Where paragraph (2) of EASA AD 2019-0073 specifies to replace if there are burn signs or other damage, for this AD, other damage is defined as being consistent with wire overheat (e.g., possible melted or exposed wires).
Although the service information referenced in EASA AD 2019-0073 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
