Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to 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, as identified in Transport Canada AD CF-2022-67, dated December 6, 2022 (Transport Canada AD CF-2022-67).
The FAA is superseding Airworthiness Directive (AD) 2021-09- 03, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-09-03 required repetitive replacements of the emergency locator transmitter (ELT) antenna and repetitive inspections of the exterior fuselage skin around the ELT antenna attachment area. This AD was prompted by a report that there was an in-service failure of an ELT antenna that occurred before the repetitive replacement interval required by AD 2021-09-03, and that a terminating action was developed. This AD continues to require the actions in AD 2021-09-03 and requires replacement of the ELT antenna with a new ELT antenna, inspection of the exterior fuselage skin around the ELT antenna attachment holes, and repair 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-2022-67.
(1) Where Transport Canada AD CF-2022-67 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2022-67 refers to April 1, 2021 (the effective date of Transport Canada AD CF-2021-10, dated March 18, 2021), this AD requires using May 4, 2021 (the effective date of AD 2021-09-03).
(3) Where Transport Canada AD CF-2022-67 refers to hours air time, this AD requires using flight hours.
(4) Where paragraph C of Transport Canada AD CF-2022-67 specifies to “replace the ELT antenna with a new aluminum ELT antenna and inspect the exterior fuselage skin around the ELT antenna attachment holes for damage, repairing any damage found before further flight,” this AD requires replacing that text with “replace the ELT antenna with a new aluminum ELT antenna, including doing an inspection of the exterior fuselage skin around the ELT antenna attachment holes for damage, and, before further flight, repair any damage found.”
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 the address identified in paragraph (j) of this AD. Information may be emailed to: 9-AVS-NYACO-COS@faa.gov.
(i) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(ii) AMOCs approved previously for AD 2021-09-03 are not approved as AMOCs for the corresponding provisions of Transport Canada AD CF-2022-67 that are required by paragraph (g) of this AD.
(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's Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
