ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL- 600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a report that Belleville washers installed on the shimmy damper of the main landing gear (MLG) may fail due to fatigue. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a repetitive task specified in the maintenance review board (MRB) report. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 12, 2018. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 12, 2018.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL- 600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on January 2, 2018 (83 FR 83) (``the NPRM''). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2017-14, dated April 21, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states: It has been found that Belleville washers installed on the Main Landing Gear (MLG) Shimmy Damper may fail in fatigue. A failed washer segment migrating into the piston cavity may interfere with piston travel. As a result, shimmy damper performance would be compromised, MLG shimmy could occur and potentially lead to a MLG failure. As a result of this investigation, a restoration task has been added for Belleville washers' replacement at 20,000 flight cycles, during MLG overhaul. For aeroplanes that have passed the 20,000 flight cycle threshold, a phase-in period is defined. This [Canadian] AD is issued to mandate the Maintenance Review Board (MRB) [[Page 26353]] revised task for the affected aeroplanes models. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 1175. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA's response to that comment. Request to the Contact Manufacturer for Service Information Bombardier stated that task number 320100-229, Restoration (Belleville Washer Replacement) of the MLG Shimmy Damper, of the MRB Report of the Bombardier CRJ700/900/1000 Maintenance Requirements Manual (MRM)--Part 1, Volume 1, CSP B-053, Revision 17, dated June 25, 2017, is currently specified in paragraph (g) of the proposed AD. Bombardier commented that it is planning to issue Revision 18 of the service information by June 25, 2018. Bombardier stated to contact Bombardier for the latest service information should the AD be published after June 25, 2018. We expect to issue this AD prior to the anticipated date of release of new service information, and we do not agree to delay issuance of this AD until new service information is released. However, if new service information is released after this AD is issued, operators may request approval of an alternative method of compliance (AMOC) under the provisions of paragraph (j)(1) of this AD. We have not changed this AD regarding this issue. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD as proposed, except for minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier has issued MRB report task number 320100-229, Restoration (Belleville Washer Replacement) of the MLG Shimmy Damper, of the MRB Report of the Bombardier CRJ700/900/1000 Maintenance Requirements Manual (MRM)--Part 1, Volume 1, CSP B-053, Revision 17, dated June 25, 2017. This service information describes the restoration (Belleville Washer Replacement) of the MLG shimmy damper. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 544 airplanes of U.S. registry. We estimate the following costs to comply with this AD: We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per- operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour). Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: 1. Is not a ``significant regulatory action'' under Executive Order 12866, 2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), 3. Will not affect intrastate aviation in Alaska, and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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): 2018-11-12 Bombardier, Inc., Airplanes: Amendment 39-19300; Docket No. FAA-2017-1175; Product Identifier 2017-NM-087-AD. (a) Effective Date This AD is effective July 12, 2018. (b) Affected ADs None. (c) Applicability This AD applies to all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes, certificated in any category. [[Page 26354]] (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Reason This AD was prompted by a report indicating that Belleville washers installed on the shimmy damper of the main landing gear (MLG) may fail due to fatigue. We are issuing this AD to prevent a failed washer segment migrating into the piston cavity and interfering with piston travel. As a result, the shimmy damper performance could be compromised, and an MLG shimmy could occur, potentially leading to an MLG failure and affecting the airplane's safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Maintenance or Inspection Program Revision Within 30 days after the effective date of this AD, revise the airplane maintenance or inspection program, as applicable, by incorporating maintenance review board (MRB) report task number 320100-229, Restoration (Belleville Washer Replacement) of the MLG Shimmy Damper, of the MRB Report of the Bombardier CRJ700/900/1000 Maintenance Requirements Manual (MRM)--Part 1, Volume 1, CSP B-053, Revision 17, dated June 25, 2017. The initial compliance time for MRB report task number 320100-229 is specified in paragraphs (g)(1) and (g)(2) of this AD, as applicable. (1) For any shimmy damper with 20,000 total accumulated flight cycles or fewer as of the effective date of this AD, the initial compliance time is before the accumulation of 26,000 total flight cycles. (2) For any shimmy damper with 20,000 total accumulated flight cycles or more as of the effective date of this AD, the initial compliance time is specified in paragraph (g)(2)(i) or (g)(2)(ii), whichever occurs later. (i) Within 6,000 flight cycles after the effective date of this AD, but prior to the accumulation of 30,000 total flight cycles. (ii) Within 30 days after effective date of this AD. (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 Temporary Revision MRB-0070, dated October 20, 2015. (i) No Alternative Actions and/or Intervals After the airplane maintenance or inspection 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 alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD. (j) 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.
