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): 2017-23-09 Bombardier, Inc.: Amendment 39-19103; Docket No. FAA- 2017-0338; Product Identifier 2016-NM-153-AD. (a) Effective Date This AD is effective December 26, 2017. (b) Affected ADs None. [[Page 55042]] (c) Applicability This AD applies to the Bombardier, Inc., airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category. (1) Bombardier, Inc., Model CL-600-2A12 (CL-601) airplanes, having serial numbers (S/Ns) 3001 through 3066 inclusive. (2) Bombardier, Inc., Model CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes, having S/Ns 5001 through 5194 inclusive.

(d) Subject Air Transport Association (ATA) of America Code 05, Periodic inspections. (e) Reason This AD was prompted by a determination that the bushing holes on the engine mount rib may not conform to the engineering drawings and that certain inspections of the engine mount rib must be included in the airworthiness limitations section (ALS) of the Instructions for Continued Airworthiness (ICA). We are issuing this AD to detect and correct failure of an engine mount rib. Failure of an engine mount rib could compromise the structural integrity of the engine mount and could lead to subsequent detachment of an engine. (f) Compliance Comply with this AD within the compliance times specified, unless already done.(g) Maintenance or Inspection Program Revision Within 60 days after the effective date of this AD: Revise the maintenance or inspection program, as applicable, to incorporate inspections for fatigue cracking of the engine mount rib and corrective actions, as applicable, in accordance with a method approved by the Manager, New York ACO Branch, FAA. Note 1 to paragraph (g) of this AD: Guidance can be found in Tasks 54-10-00-106 and 54-50-00-103 of Chapter 5 of the Bombardier Time Limits/Maintenance Checks (TLMC) Manual PSP 601-5 (for Model CL-600-2A12 (CL-601 Variant) airplanes); Bombardier TLMC Manual PSP 601A-5 (for CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes); Bombardier TLMC Manual CL-604 (for Model CL-600-2B16 (CL-604 Variant) airplanes, S/Ns 5301 through 5665 inclusive); and Bombardier TLMC Manual CL-605 (for Model CL-600-2B16 (CL-604 Variant) airplanes, S/Ns 5701 through 5990). (h) No Alternative Actions and/or Intervals After the maintenance orinspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) and/or intervals may be used, unless the actions and/or intervals are approved as an AMOC in accordance with the procedures specified in paragraph (i)(1) of this AD. (i) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to ATTN: Program Manager, Continuing Operational Safety, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516-228-7300; fax 516-794-5531. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished 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.
