Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2017-25-07 Alexander Schleicher GmbH & Co. Segelflugzeugbau: Amendment 39-19121; Docket No. FAA-2017-0911; Product Identifier 2017-CE-025-AD. (a) Effective Date This airworthiness directive (AD) becomes effective January 18, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Alexander Schleicher GmbH & Co. Segelflugzeugbau Models ASH 25M and ASH 26E gliders, all serial numbers, that: (1) Have an exhaust silencer, part number (P/N) 800.65.0001, installed; and (2) are certificated in any category. (d) Subject Air Transport Association of America (ATA) Code 78: Engine Exhaust. (e) Reason This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue cracks found on the exhaust silencer. We are issuing this AD to prevent heat damage in the engine compartment and to the engine installation, which could result in reduced control. (f) Actions and Compliance Unless already done, do the following actions: (1) Before exceeding 150 hours time-in-service (TIS) on the exhaust silencer, P/N 800.65.0001, since new, or within the next 5 hours TIS after January 18, 2018 (the effective date of this AD), whichever occurs later, replace P/N 800.65.0001 with an improved exhaust silencer, P/N 800.65.9010. Do the replacement as specified in Alexander Schleicher GmbH & Co. Segelflugzeugbau ASK 21 Mi Technical Note No. 11, ASW 22 BLE 50 R Technical Note No. 16, ASH 25 M/Mi Technical Note No. 32, ASH 26 E Technical Note No. 19 (single document), dated January 8, 2016.
