Airworthiness Directive · Amendment 39-22759 · Aircraft fuel filter/strainer
Airbus Helicopters
Superseded. A later AD replaced this one: AD 2025-24-05. Comply with the one in force.
This AD applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, and EC225LP helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332C, AS332C1, AS3322L, AS332L1, AS332L2, and EC225LP helicopters. This AD was prompted by a report of cracks on the fuel filter bowl (bowl) due to over-torquing. This AD requires visually inspecting the bowls of the right hand (RH) and left hand (LH) fuel filters for any cracks and seepage. Depending on the inspection results, this AD requires removing an affected fuel filter from service and replacing that part. This AD also allows a certain fuel filter to be installed on a helicopter if certain actions are accomplished. These requirements are 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 paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0095, dated May 8, 2023 (EASA AD 2023-0095).
(1) Where EASA AD 2023-0095 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2023-0095 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2023-0095 requires an inspection “in accordance with the instructions of the applicable ASB,” for this AD, replace that text with, “in accordance with paragraph 3.B.2.a. of the applicable ASB, except you are not required to comply with paragraph 3.B.2.b or 3.B.3.”
(4) Where paragraph (2) of EASA AD 2023-0095 states “replace the affected part with a serviceable part in accordance with the instructions of the applicable ASB,” this AD requires replacing those words with “remove the affected part from service and replace it with a serviceable part.”
(5) Where the service information referenced in EASA AD 2023-0095 specifies to “make sure that there is no crack and no seepage on the bowls (a) of the RH and LH fuel filters (b),” this AD requires replacing those words with “Inspect for any crack and seepage on the bowls (a) of the RH and LH fuel filters (b).”
(6) Where the service information referenced in EASA AD 2023-0095 specifies “If there is a crack and/or a seepage on the bowls (a) of the RH and LH fuel filters (b), comply with paragraph 3.B.2.b.,” this AD requires replacing that text with “If there is a crack or seepage on the bowls (a) of the RH or LH fuel filter (b), before further flight, remove the affected part from service and replace with a serviceable part, as defined in EASA AD 2023-0095.”
(7) This AD does not adopt the “Remarks” section of EASA AD 2023-0095.
Although the service information referenced in EASA AD 2023-0095 specifies to submit certain information and return parts to the manufacturer, this AD does not include those requirements.
