2018-18-02: Reciprocating Engine Power Section

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): \n\nAD 2018-18-02; Austro Engine GmbH Engines: Amendment 39-19381; Docket No. FAA-2017-1138; Product Identifier 2017-NE-41-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective November 29, 2018. \n\n(b) Affected Ads \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to Austro Engine GmbH model E4 engines with serial numbers that have a ''-B'' or ''-C'' configuration and to model E4P engines, all serial numbers. \n\n(d) Subject \n\n\n\tJoint Aircraft System Component (JASC) Code 8520, Reciprocating Engine Power Section. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by reports of considerable wear on the timing chain on these engines. We are issuing this AD to prevent failure of the engine timing chain. The unsafe condition, if not addressed, could result in failure of the engine timing chain, loss of engine thrust control, and reduced control of the airplane. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Required Actions \n\n\n\t(1) Determine whether the engine is a Group 1 or Group 2 engine as follows. \n\t(i) A Group 1 engine is an engine equipped with a timing chain that was installed on an engine that experienced a windmill restart, or an engine in which it cannot be determined if the engine experienced any windmilling restarts. \n\t(ii) A Group 2 engine is an engine that is equipped with a timing chain that has not experienced any windmilling restarts. \n\t(2) For Group 1 engines: Before the affected timing chain exceeds 945 engine flight hours (EFHs) since installation on an engine, or within 110 EFHs after the effective date of this AD, whichever occurs later, replace the timing chain in accordance with the instructions in Technical Details, paragraph 2, in Austro Engine Mandatory Service Bulletin (MSB) No. MSB-E4-017/2, Revision 2, dated December 2, 2016. \n\t(3) For Group 1 and Group 2 engines: After the effective date of this AD, following each windmill restart of an engine, before the timing chain of that engine exceeds 945 EFHs since first installation on an engine, or within 110 EFHs after that windmilling restart, whichever occurs later, replace the timing chain in accordance with the instructions in Technical Details, paragraph 2, in Austro Engine MSB No. MSB-E4-017/2, Revision 2, dated December 2, 2016. \n\t(4) For Group 1 and Group 2 engines: Within 30 days after the effective date of this AD, amend the applicable airplane flight manual under emergency procedures by adding the information in figure 1 to paragraph (g)(4) of this AD to limit the use of a windmilling restart to only an emergency procedure. \n\n((Page 53805)) \n\n(GRAPHIC) (TIFF OMITTED) TR25OC18.000 \n\n\n\t(5) For affected Austro Engine GmbH model E4 engines installed on Diamond Aircraft Industries (DAI) model DA 42 NG and DA 42 M-NG airplanes and for Austro Engine GbmH model E4P engines installed on DAI model DA 62 airplanes, using Airplane Flight Manual (AFM) Temporary Revision (TR) TR-M(Auml)M-42-973, and AFM TR TR-M(Auml)M- 62-240, both dated August 12, 2016, respectively, to update the applicable AFM is an acceptable method to comply with paragraph (g)(4) of this AD. \n\n(h) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The manager, ECO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
