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 removing Airworthiness Directive (AD) 2012-22-10, Amendment 39-17246 (77 FR 67267, November 9, 2012), and adding the following new AD: 2018-20-17 Bombardier, Inc.: Amendment 39-19451; Docket No. FAA- 2018-0587; Product Identifier 2018-NM-054-AD. (a) Effective Date This AD is effective November 20, 2018. (b) Affected ADs This AD replaces AD 2012-22-10, Amendment 39-17246 (77 FR 67267, November 9, 2012) (``AD 2012-22-10''). (c) Applicability This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category. (1) Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers 10002 and subsequent.

We are issuing this AD to address loss of the wing-to-fuselage attachment joints, which could result in loss of the wing, and consequent reduced, or complete loss of, controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Initial Inspection of the Wing-to-Fuselage Attachment Joint For airplanes identified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD: Within 3,000 flight hours or 18 months, whichever occurs first after December 14, 2012 (the effective date of AD 2012- 22-10), perform a detailed inspection for missing or failed cotter pins at each affected wing-to-fuselage attachment joint, in accordance with Part A through Part C of the Accomplishment Instructions of Bombardier Service Bulletin 670BA-53-042, Revision B, dated October 20, 2017.
