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 airworthiness directive (AD): 2014-20-09 Bombardier, Inc.: Amendment 39-17982. Docket No. FAA- 2013-1067; Directorate Identifier 2013-NM-164-AD. (a) Effective Date This AD becomes effective November 7, 2014. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc. Model DHC-8-400, -401, and - 402 airplanes, certificated in any category, serial numbers 4001 through 4347 inclusive. (d) Subject Air Transport Association (ATA) of America Code 24, Electrical power. (e) Reason This AD was prompted by reports of missingclamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension. We are issuing this AD to detect and correct chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension system, could result in an in-flight fire. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Clamp Inspection, Related Investigative Actions, and Corrective Actions Within 6,000 flight hours or 36 months after the effective date of this AD, whichever occurs earlier: Do a general visual inspection for installation of clamps between the AC feeder cables and hydraulic line; and do all applicable related investigative and corrective actions; in accordance with paragraph 3.B., ``Procedure,'' of the Accomplishment Instructions of Bombardier Service Bulletin 84-24-53, Revision A, dated May 16, 2013. Do all applicable related investigative and corrective actions before further flight. (h) Credit for Previous Actions This paragraph provides credit for actions required by paragraph (g) of this AD, if those actions were performed before the effective date of this AD using Bombardier Service Bulletin 84-24-53, dated May 11, 2012.
