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: 2024-03-08 Bombardier, Inc.: Amendment 39-22678; Docket No. FAA-2023-2000; Project Identifier MCAI-2023-00415-T. (a) Effective Date This airworthiness directive (AD) is effective May 3, 2024. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9002 through 9879 inclusive, 9998, and 60001 and subsequent. (d) Subject Air Transport Association (ATA) of America Code: 36, Pneumatic. (e) Unsafe Condition This AD was prompted by reports that some overheat detection sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill. The FAA is issuing this AD to address non-conforming sensing elements of the bleed air leak detection system. The unsafe condition, if not addressed, could result in an inability to detect hot bleed air leaks and consequent damage to surrounding structures and systems, which could prevent continued safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Definitions For the purpose of this AD, the definitions specified in paragraphs (g)(1) through (3) of this AD apply. (1) The following Model BD-700-1A10 and BD-700-1A11 airplane groups are identified in (g)(1)(i) through (iv) of this AD: (i) Group A airplanes: serial numbers (S/N) 9002 through 9151 inclusive, and 9153. (ii) Group B airplanes: S/N 9152, 9154 through 9879 inclusive, 9998, 60001 through 60041 inclusive, 60043, 60044, 60045, and 60051. (iii) Group C airplanes: S/N 60042, 60046, 60047, 60049, 60053, and subsequent. (iv) Group D airplanes: S/N 60048, 60050, and 60052. (2) An affected part is a sensing element marked with a date code A0448 through A2104 inclusive and having an LTS/Kidde part number specified in Liebherr Service Bulletin CFD-F1958-26-01, dated May 6, 2022, unless that sensing element meets the criteria specified in paragraph (g)(2)(i) or (ii) of this AD. (i) The sensing element has been tested as specified in Section 3 of the Accomplishment Instructions of Kidde Aerospace and Defense Service Bulletin CFD-26-1, Revision 6, dated February 28, 2022, or earlier revisions, and has been found to be serviceable; and the sensing element has been marked on one face of its connector hex nut and packaged as specified in Section 3.C. of the Accomplishment Instructions of Kidde Aerospace and Defense Service Bulletin CFD-26-1, Revision 6, dated February 28, 2022, or earlier revisions. (ii) The sensing element has been tested and found to be serviceable as specified in paragraph (j) of this AD; and the sensing element has been marked on one face of one connector hex nut with one green mark, as specified in Figure 4 (the figure is representative for all sensing elements) in the Accomplishment Instructions of the applicable Bombardier service bulletin (BA SB) in figure 1 to paragraph (g)(2)(ii) of this AD. Figure 1 to Paragraph (g)(2)(ii)-Applicable Service Information BILLING CODE 4910-13-P ER29MR24.003 (3) A serviceable part is a sensing element that is not an affected part. (h) Maintenance Records Verification For Groups A and C whose airplane date of manufacture, as identified on the identification plate of the airplane or in the aircraft maintenance logbook, is on or before July 27, 2022 (the effective date of Transport Canada AD CF-2022-38): Within 60 days after the effective date of this AD, examine the airplane maintenance records to verify whether any affected part has been installed since the airplane date of manufacture, as identified on the identification plate of the airplane or in the aircraft maintenance logbook. (1) If the maintenance records confirm that an affected part has been installed, or if it cannot be confirmed that an affected part has not been installed, paragraphs (i) and (j) of this AD must be complied with within the applicable compliance times specified in paragraphs (i) and (j) of this AD. (2) For Groups A and C airplanes: if the maintenance records confirm that no affected parts have been installed since airplane date of manufacture, then paragraphs (i) and (j) of this AD are not applicable. (i) Minimum Equipment List (MEL) Revision For Groups B and D airplanes, and Groups A and C airplanes required by paragraph (h) of this AD: Within 90 days after the effective date of this AD, revise the operator's existing MEL by incorporating the information specified in figures 2 through 8 to paragraph (i) of this AD, as applicable. This may be done by inserting a copy of this information into the operator's existing MEL.
