Airworthiness Directive · Amendment 39-23125 · Hydraulic power
ATR-GIE Avions de Transport Régional Airplanes
This AD applies to ATR—GIE Avions de Transport Régional Model ATR42-500 and ATR72-212A airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2025-0103, dated May 5, 2025 (EASA AD 2025-0103).
The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72-212A airplanes. This AD was prompted by a finding that dispatch with a failed main hydraulic pump under the provisions of a certain master minimum equipment list (MMEL) item, combined with failure of the DC EMER BUS, could lead to failure of multiple system losses. This AD requires revising the existing minimum equipment list (MEL) to incorporate new provisions to ensure appropriate actions are taken when the airplane is dispatched with one inoperative main hydraulic pump. 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 2025-0103.
(1) Where EASA AD 2025-0103 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (1) of EASA AD 2025-0103 specifies to “implement the instructions of the MMEL items”, this AD requires replacing that text with “revise the operator's existing FAA-approved MEL by incorporating the information identified in “The MMEL items” ”.
(3) Where paragraph (1) of EASA AD 2025-0103 specifies to “inform all flight crews, and thereafter, operate the aeroplane accordingly,” this AD does not require those actions as those actions are already required by existing FAA operating regulations (see 14 CFR 121.628(a)(2) and (5)).
(4) This AD does not adopt paragraph (2) of EASA AD 2025-0103.
(5) This AD does not adopt the “Remarks” section of EASA AD 2025-0103.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, International Validation Branch, FAA; or EASA; or ATR—GIE Avions de Transport Régional's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
