[Federal Register Volume 80, Number 193 (Tuesday, October 6, 2015)] [Rules and Regulations] [Pages 60281-60284] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-25219] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2014-1046; Directorate Identifier 2014-NM-021-AD; Amendment 39-18286; AD 2015-20-07] RIN 2120-AA64 Airworthiness Directives; Bombardier, Inc. Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a determination that no instructions for continued airworthiness exist for the nose landing gear (NLG) alternate extension actuator of the NLG alternate release system. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation task for the NLG alternate extension actuator. We are issuing this AD to prevent failure of the NLG alternate release system and, if the normal NLG extension system also fails, failure of the NLG to extend, and consequent damage to the airplane and injury to occupants. DATES: This AD becomes effective November 10, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 10, 2015.

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 certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. The NPRM published in the Federal Register on January 23, 2015 (80 FR 3502). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2013-24R1, dated December 24, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model CL-600- 2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. The MCAI states: It was discovered that there are no instructions for continued airworthiness for the Nose Landing Gear (NLG) alternate extension actuator. Without an effective maintenance task to maintain the aeroplane's inherent level of safety, there is a potential that a dormant failure of the alternate release system of the NLG could occur. Failure of the NLG alternate release system could prevent the nose landing gear from extending in the case of a failure of the normal NLG extension system. This [Canadian] AD is to mandate the incorporation of a new maintenance task to prevent failure of the NLG alternate release system. Revision 1 of this [Canadian] AD changes the phase-in time to be based on the NLG manual release actuators instead of aeroplanes. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-1046-0002. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 3502, January 23, 2015) and the FAA's response to each comment. Support for the NPRM (80 FR 3502, January 23, 2015) Airline Pilots Association (ALPA) International agreed with the intent of the NPRM (80 FR 3502, January 23, 2015). Request To Revise Compliance Time Envoy Airlines and Mesa Airlines asked that we revise the compliance time language in paragraph (h) of the proposed AD (80 FR 3502, January 23, 2015) from ``whichever occurs first'' to ``whichever occurs later.'' The compliance time, as written, could result in airplanes being grounded. Envoy Airlines added that the compliance time referred to in the TCCA AD is ``whichever occurs later.'' Mesa Airlines noted that changing the compliance time would also allow for scheduling and parts procurement. We agree with the commenters' request for the reasons provided, and due to the fact that this was an inadvertent error. We have revised the compliance time in paragraph (h) of this AD as requested. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM (80 FR 3502, January 23, 2015) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 3502, January 23, 2015). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Task 320100-225, Restoration of the NLG Manual Release Actuator, of Subject 1-32, Landing Gear, of Section 1, Systems and Powerplant Program, Volume 1 of Part 1, Maintenance Review Board Report, Revision 14, dated July 10, 2013, of the CRJ 700/900/1000 Maintenance Requirements Manual, CSP-B-053. This service information describes an airworthiness limitation task for the NLG alternate extension actuator. 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 of this AD. Costs of Compliance We estimate that this AD affects 416 airplanes of U.S. registry. We also estimate that it takes about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $35,360, or $85 per product. In addition, we estimate that any necessary follow-on actions take about 1 work-hour and require parts costing $0, for a cost of $85 per product. We have no way of determining the number of aircraft that might need these actions. 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 [[Page 60283]] because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. 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.
