Airworthiness Directive · Amendment 39-21671 · Emergency flotation section
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AW189 helicopters, certificated in any category, as identified in European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD 2018-0006, dated January 10, 2018 (EASA AD 2018-0006).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by corrosion on the inlet check valve banjo fitting of emergency flotation system (EFS) float assemblies. This AD requires visually inspecting each banjo fitting installed on an affected EFS float assembly, and depending on the results, removing the banjo fitting from service. This AD also requires applying corrosion inhibiting compound and prohibits installing an affected EFS float assembly unless certain requirements have been accomplished 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.
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 2018-0006.
(1) Where EASA AD 2018-0006 refers to December 29, 2017 (the effective date of EASA AD 2017-0256, dated December 22, 2017), this AD requires using the effective date of this AD.
(2) Where the service information referenced in EASA AD 2018-0006 specifies to return a certain part, this AD requires removing that part from service.
(3) Where the service information referenced in EASA AD 2018-0006 specifies to discard certain parts, this AD requires removing those parts from service.
(4) The “Remarks” section of EASA AD 2018-0006 does not apply to this AD.
Although the service information referenced in EASA AD 2018-0006 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
