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): 2019-12-08 Bombardier, Inc.: Docket No. FAA-2019-0119; Product Identifier 2018-NM-156-AD. (a) Effective Date This AD is effective August 12, 2019. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., airplanes, certificated in any category, as identified in paragraphs (c)(1) and (c)(2) of this AD. (1) Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers (S/Ns) 15336 through 15343 inclusive, 15351, and 15358 through 15362 inclusive. (2) Model CL-600-2E25 (Regional Jet Series 1000) airplanes, S/N 19041. (d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. (e) Reason This AD was prompted by reports that certain aft fuselage fittings are susceptible to cracking because they were not manufactured correctly. The FAA is issuing this AD to address the possibility of undetected cracks developing in the aft fuselage fittings due to the absence of heat treatment, which could lead to aircraft structural failure. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Within 8,800 flight hours after the effective date of this AD, remove all aft fuselage fittings, replace with new aft fuselage fittings, and do an eddy current inspection of the fastener holes of frame FS1162.00 and stringers 17L, 17R, and 18L for cracking, in accordance with Part C of the Accomplishment Instructions of Bombardier Service Bulletin 670BA-53-056, dated February 11, 2016. (h) Corrective Action for Cracking If any crack is found during any inspection required by paragraph (g) of this AD: Before further flight, repair using a method approved by the Manager, New York ACO Branch, FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
