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: 2023-09-10 Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics): Amendment 39-22433; Docket No. FAA-2023-1039; Project Identifier MCAI-2023-00580-T. (a) Effective Date This airworthiness directive (AD) is effective May 31, 2023. (b) Affected ADs None. (c) Applicability This AD applies to all Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics) Model 340A (SAAB/SF340A) and SAAB 340B airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 24, Electrical Power. (e) Unsafe Condition This AD was prompted by the reports of excessive wear on certain starter generator brushes installed in the starter generator. The FAA is issuing this AD to address the problem associated with excessive wear on the starter generator brushes and the unusual conditions at the brush attachment location. This condition, if not detected and corrected, could lead to starter generator failure(s), possibly resulting in total loss of generated electrical power with consequent reduced functional capability of the airplane. (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, EASA AD 2023-0073, dated April 5, 2023 (EASA AD 2023-0073). (h) Exceptions to EASA AD 2023-0073 (1) Where EASA AD 2023-0073 refers to its effective date, this AD requires using the effective date of this AD. (2) This AD does not adopt the "Remarks" section of EASA AD 2023-0073. (3) Paragraph (5) of EASA AD 2023-0073 specifies to report inspection results to SAAB AB within a certain compliance time. For this AD, report inspection results at the applicable time specified in paragraph (h)(3)(i) or (ii) of this AD. (i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.

If approved by the DOA, the approval must include the DOA-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.
