2023-20-01: Fire protection

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2023-20-01 Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): Amendment 39-22560; Docket No. FAA-2023-1501; Project Identifier MCAI-2023-00647-T. (a) Effective Date This airworthiness directive (AD) is effective November 9, 2023. (b) Affected ADs None. (c) Applicability 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-2023-28, dated May 4, 2023 (Transport Canada AD CF-2023-28). (d) Subject Air Transport Association (ATA) of America Code: 26, Fire protection. (e) Unsafe Condition This AD was prompted by a report the engine fire extinguishing control and indication system did not illuminate correctly. The FAA is issuing this AD to address the misleading indication given by the AVAIL legend on BTL 1 and BTL 2 push button annunciators (PBAs) that will affect the crew's assessment of the situation. The unsafe condition, if not addressed, could result in the crew hesitating to extinguish an engine fire despite having access to a functional engine fire extinguishing system, or reselecting the FIRE PBA, resulting in loss of the ability to isolate and extinguish the fire. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements 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-2023-28. (h) Exceptions to Transport Canada AD CF-2023-28 (1) Where Transport Canada AD CF-2023-28 refers to its effective date, this AD requires using the effective date of this AD. (2) Where Transport Canada AD CF-2023-28 specifies installing software updates on the integrated cockpit control panel remote data concentrator using a USB-type device, this AD also allows the use of a portable maintenance access terminal (PMAT)-type device. Note 1 to paragraph (h)(2): When using a PMAT-type device, guidance for upgrading the software can be found in Airbus Canada Limited Partnership Service Bulletin BD500-311001, Issue 001, dated March 14, 2023. (i) Additional AD Provisions 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)(1) of this AD or email to: [email protected]. 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's 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 paragraph (i)(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.
