Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (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 removing airworthiness directive (AD) 2013-04-08 (78 FR 14160, March 5, 2013) and adding the following new AD: 2013-04-08 R1 Diamond Aircraft Industries GmbH: Amendment 39-17447; Docket No. FAA-2012-1172; Directorate Identifier 2012-CE-040-AD. (a) Effective Date This AD is effective May 6, 2013. (b) Affected ADs This AD revises AD 2013-04-08 (78 FR 14160, March 5, 2013), Amendment 39-17365. (c) Applicability This AD applies to the following Diamond Aircraft Industries GmbH models and serial number (S/N) powered gliders, certificatedin any category: HK 36 R powered gliders, S/Ns 36.300 through 36.414; HK 36 TS powered gliders, S/Ns 36.415 and 36.416; and HK 36 TTS powered gliders, S/N 36.393. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) Code 27: Flight Controls. (e) Unsafe Condition This AD was prompted by reports of installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this revised AD because we evaluated all the relevant information and determined it is not necessary or possible for the Diamond Aircraft Industries GmbH Model H-36 to comply with the previous AD.
