Airworthiness Directive · Amendment 39-22521 · Fuel
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to all Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by reports of mechanical wear damage found on the engine fuel feed system tubes and fuel tube connections. This AD requires repetitive inspections of the fuel feed system for damage, and replacement if necessary, as specified in a Transport Canada 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, Transport Canada AD CF-2022-08, dated March 3, 2022 (Transport Canada AD CF-2022-08).
(1) Where Transport Canada AD CF-2022-08 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph B. of Part 1 of Transport Canada AD CF-2022-08 specifies a compliance time for accomplishing the inspection, for this AD, the inspection must be done at the time specified in paragraph (h)(2)(i) or (ii) of this AD, whichever occurs later.
(i) The compliance time specified in paragraph B. of Part 1 of Transport Canada AD CF-2022-08.
(ii) Within 60 flight hours or 7 days after the effective date of this AD, whichever occurs first.
(3) Where paragraph B. of part II of Transport Canada AD CF-2022-08 specifies a compliance time for accomplishing the inspection, for this AD, the inspection must be done at the time specified in paragraph (h)(3)(i) or (ii) of this AD, whichever occurs later.
(i) The compliance time specified in paragraph B. of Part II of Transport Canada AD CF-2022-08.
(ii) Within 60 flight hours or 7 days after the effective date of this AD, whichever occurs first.
(4) Where Transport Canada AD CF-2022-08 refers to “hours air time,” this AD requires replacing those words with “flight hours.”
(5) Where Transport Canada AD CF-2022-08 specifies to “rectify any discrepancy,” this AD requires replacing those words with “if any mechanical wear damage is found on which the measured damage exceeds the allowable limits identified in ACLP SB BD500-282006, before further flight replace the affected part.”
(6) Where the service information referenced in Transport Canada AD CF-2022-08 specifies “washer part number NAS1149E0332R,” this AD requires replacing those words with “washer part number NAS1149D0332J.”
(7) Where Transport Canada AD CF-2022-08 requires actions “in accordance with Parts C and D Accomplishment Instructions of ACLP SB BD500-282006,” and “in accordance with Parts A and B Accomplishment Instructions of ACLP SB BD500-282006,” this AD requires replacing those words with “in accordance with Section 3 Procedure in each Part of the Accomplishment Instructions of ACLP SB BD500-282006.”
Although the service information referenced in Transport Canada AD CF-2022-08 specifies to submit certain information 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, 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, mail it to ATTN: Program Manager, Continuing Operational Safety, at the address identified in paragraph (k) of this AD or email to 9-AVS-NYACO-COS@faa.gov. If mailing information, also submit information by email. 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 Transport Canada; or Airbus Canada Limited Partnership Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-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 that are identified as RC, those procedures must be done to comply with this AD; any procedures that are not identified as RC are recommended. Those procedures 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 identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures identified as RC require approval of an AMOC.
