Airworthiness Directive · Amendment 39-21782 · Engine drains
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AW189 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2019-0039, dated February 20, 2019 (EASA AD 2019-0039).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by a report that a number of fairleads that support the engine combustion chamber D1 drain hose showed evidence of heat damage. This AD requires modifying the helicopter by installing a certain engine combustion chamber D1 drain assembly, 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 2019-0039.
(1) Where EASA AD 2019-0039 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2019-0039 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where the service information required by EASA AD 2019-0039 specifies discarding parts, this AD requires removing those parts from service.
(4) This AD does not require the “Remarks” section of EASA AD 2019-0039.
Although the service information referenced in EASA AD 2019-0039 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
