Airworthiness Directive · Amendment 39-22087 · Aircraft fuel system
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AW169 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2021-0238, dated November 2, 2021 (EASA AD 2021-0238).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by a report of a blockage in a fuel tank vent line. This AD requires inspecting the fuel tank vent lines, 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 2021-0238.
(1) Where EASA AD 2021-0238 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2021-0238 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where the service information referenced in paragraph (1) of EASA AD 2021-0238 specifies recording the inspection outcome in the report in ANNEX A (of the service information), this AD does not require that action.
(4) Where the service information referenced in paragraph (1) of EASA AD 2021-0238 specifies inspecting “the left/right vent line for evidence of a partial or total Proseal obstruction,” this AD requires inspecting for a partial or total Proseal obstruction.
(5) Where the service information referenced in EASA AD 2021-0238 specifies immediately contacting Leonardo Company Product Support Engineering and waiting for further instructions before proceeding if there is any Proseal obstruction in any fuel tank vent line, this AD does not require that action.
(6) Where the service information referenced in paragraph (2) of EASA AD 2021-0238 specifies to “carefully remove the Proseal obstruction by means of a suitable method,” this AD requires, before further flight, accomplishing repairs in accordance with a method approved by the Manager, General Aviation & Rotorcraft Section, International Validation Branch, FAA; or EASA; or Leonardo S.p.a. Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(7) Where paragraph (2) of EASA AD 2021-0238 specifies contacting Leonardo for approved corrective actions and accomplishing those instructions within the compliance time specified therein, this AD requires, before further flight, accomplishing repairs in accordance with a method approved by the Manager, General Aviation & Rotorcraft Section, International Validation Branch, FAA; or EASA; or Leonardo S.p.a. Helicopters' EASA DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
(8) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0238.
Although the service information referenced in EASA AD 2021-0238 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.
