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: a. Removing Airworthiness Directive 2017-18-10, Amendment 39-19019 (82 FR 42029, September 6, 2017); and b. Adding the following new airworthiness directive: 2022-06-08 Diamond Aircraft Industries GmbH: Amendment 39-21974; Docket No. FAA-2021-1077; Project Identifier MCAI-2021-00607-A. (a) Effective Date This airworthiness directive (AD) is effective May 9, 2022. (b) Affected ADs This AD replaces AD 2017-18-10, Amendment 39-19019 (82 FR 42029, September 6, 2017). (c) Applicability This AD applies to Diamond Aircraft Industries GmbH Model DA 42, DA 42 M-NG, and DA 42 NG airplanes, all serial numbers, certificated in any category, with a flap bell crank part number (P/N) D60-2757-11-00, up to and including revision "f" installed. (d) Subject Joint Aircraft System Component (JASC) Code 2700, Flight Control System. (e) Unsafe Condition 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 cracks and deformation on certain flap bell cranks. The FAA is issuing this AD to prevent failure of the flap bell crank. The unsafe condition, if not addressed, could result in reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Actions (1) Comply with paragraph (g)(2) or (3) of this AD at whichever compliance time in paragraph (g)(1)(i) or (ii) of this AD occurs later. (i) Before the flap bell crank accumulates 600 hours time-in-service (TIS); or (ii) Within 100 hours TIS after the effective date of this AD or within 6 months after the effective date of this AD, whichever occurs first. (2) For airplanes with a flap bell crank revision "e" or "f": Inspect the flap bell crank P/N D60-2757-11-00 for cracks and deformation and modify the flap control system by installing two spacers, P/N DS BU2-10-06-0065-C, by following section III Instructions in Diamond Aircraft Industries GmbH Work Instruction WI-MSB 42-126 and WI-MSB 42NG-066, Revision 1, dated November 14, 2019 (issued as one document) attached to Diamond Aircraft Mandatory Service Bulletin MSB 42-126/1 and MSB 42NG-066/1, dated November 14, 2019 (issued as one document). (i) If there is a crack or any deformation, you must replace the flap bell crank with P/N D60-2757-11-00_01, as required by step 6 of the Instructions, before further flight. (ii) If there are no cracks and no deformation, repeat the inspection (not the modification) at intervals not to exceed 200 hours TIS until the flap bell crank is replaced with flap bell crank P/N D60-2757-11-00_01. (3) For airplanes with a flap bell crank up to revision "d": Replace the flap bell crank with P/N D60-2757-11-00_01 in accordance with section III Instructions in Diamond Aircraft Industries GmbH Work Instruction WI-MSB 42-126 and WI-MSB 42NG-066, Revision 1, dated November 14, 2019 (issued as one document) attached to Diamond Aircraft Mandatory Service Bulletin MSB 42-126/1 and MSB 42NG-066/1, dated November 14, 2019 (issued as one document). (h) Prohibited Installation As of the effective date of this AD, do not install on any airplane a flap bell crank P/N D60-2757-11-00 with a revision up to and including revision "d."
