Airworthiness Directive · Amendment 39-21998 · Pneumatic
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2022-25-17. Comply with the one in force.
This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report that certain overheat detection system (OHDS) sensing elements may not properly detect thermal bleed leak events due to a quality escape during the manufacturing process. This AD requires revising the operator's existing FAA-approved minimum equipment list (MEL) to include dispatch restrictions as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. This AD also allows operators to inspect affected parts for discrepancies, and do applicable replacements, in order to terminate the revision of the operator's existing MEL required by this AD. 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, European Union Aviation Safety Agency (EASA) AD 2022-0031, dated February 25, 2022 (EASA AD 2022-0031).
(1) Where EASA AD 2022-0031 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2022-0031 has a definition for “Affected part” and refers to “the VSB [vendor service bulletin]” for the part numbers and date codes, for this AD, use Kidde Aerospace & Defense Service Bulletin CFD-26-3, dated January 13, 2022, as “the VSB” for the part numbers and date codes.
(3) Where EASA AD 2022-0031 has a definition for “Groups” and identifies certain airplanes as Group 2 airplanes, replace the text, “An aeroplane having an MSN [manufacturer serial number] not listed in the Section 1.A of the SB is Group 2, provided it is determined that no affected part has been installed on any affected position of that aeroplane since Airbus date of manufacture” with “An aeroplane having an MSN not listed in the Section 1.A of Airbus Service Bulletin A350-36-P032, dated December 3, 2021, is Group 2, provided it is determined that no affected part has been installed on any affected position of that aeroplane since Airbus date of manufacture.”
(4) Where paragraphs (2) and (3) of EASA AD 2022-0031 require a detailed inspection of affected parts and applicable corrective actions, this AD does not require those actions, but allows performing those actions as terminating action for the revision of the operator's existing minimum equipment list (MEL) as specified in paragraph (5) of EASA AD 2022-0031.
(5) The “Remarks” section of EASA AD 2022-0031 does not apply to this AD.
(6) Where paragraph (1) of EASA 2022 0031 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.
(1) Although the service information referenced in EASA AD 2022-0031 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
(2) Although the service information referenced in EASA AD 2022-0031 specifies to return certain parts to the manufacturer, this AD does not include that requirement.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Large Aircraft Section, 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 Large Aircraft Section, International Validation Branch, send it to the attention of the person identified in paragraph (k) of this AD. Information may be emailed to: 9-AVS-AIR-730-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, Large Aircraft Section, International Validation Branch, FAA; or EASA; or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by paragraphs (i) and (j)(2) of this AD, if any service information contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
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.
