[Federal Register Volume 82, Number 108 (Wednesday, June 7, 2017)] [Proposed Rules] [Pages 26403-26406] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-11001] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0511; Directorate Identifier 2016-NM-176-AD] RIN 2120-AA64 Airworthiness Directives; Bombardier, Inc. Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a new life limitation that has been introduced for the side brace fitting shaft and side brace-to-airplane fitting pin of the main landing gear (MLG). This proposed AD would require revising the maintenance or inspection program. This proposed AD would also require an inspection to identify the serial number, to serialize, and to record the accumulated life of the side brace fitting shaft of the MLG. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by July 24, 2017.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2016-17R2, dated June 29, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model CL-600-1A11 (CL- 600), CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-3A, CL-601- 3R, and CL-604 Variants) airplanes. The MCAI states: Based on in-service experience, a new life limitation has been introduced for the following side brace fitting shaft part numbers: 600-10237-1/-5 600-10237-3 601R10237-1/-3 In order to facilitate identification and tracking, the component must be identified and serialized. Bombardier has revised the Time Limits/Maintenance Checks (TLMC) Manual to include new life limits and issued Service Bulletins (SB) for serialization of the affected parts. The original version of this [Canadian] AD was issued to mandate the incorporation of the new TLMC life limits as well as identification and serialization of the affected parts. The revision 1 of this [Canadian] AD was issued * * * June [10,] 2016 to correct a typographic error in Table A of the Corrective Actions section. The revision 2 of this [Canadian] AD is being issued to correct/ update the TLMC data in Table A of the Corrective Actions section. Required actions include an inspection to identify the serial number, to serialize, and to record the accumulated life of the side brace fitting shaft of the MLG. The unsafe condition is the loss of structural integrity of the affected part. 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-2017-0511. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. The service information describes the life limits for the side brace fitting shaft and side brace-to-airplane fitting pin of the MLG. The service information is distinct since it applies to different airplane models in different configurations. Chapter 5-10-10, Airworthiness Limitations, of the Bombardier Challenger PSP 605 Time Limits/Maintenance Checks, Revision 37, dated April 29, 2016. Chapter 5-10-10, Airworthiness Limitations, of the Bombardier Challenger PSP 601-5 Time Limits/Maintenance Checks, Revision 42, dated April 22, 2014. Chapter 5-10-10, Airworthiness Limitations, of the Bombardier Challenger PSP 601A-5 Time Limits/Maintenance Checks, Revision 38, dated April 22, 2014. Chapter 5-10-10, Airworthiness Limitations, of Part 2, of the Bombardier Challenger CL-604 Time Limits/Maintenance Checks, Revision 26, dated June 9, 2016. Chapter 5-10-10, Airworthiness Limitations, of Part 2, of the Bombardier Challenger CL-605 Time Limits/Maintenance Checks, Revision 14, dated June 9, 2016. We have also reviewed the following service information. The service information describes procedures for an inspection to identify the serial number, to serialize, and to record the accumulated life of the side brace fitting shaft of the MLG. The service bulletins are distinct since they apply to different airplane models. Bombardier Service Bulletin 600-0768, dated September 9, 2014. Bombardier Service Bulletin 601-0636, Revision 01, dated May 10, 2016. Bombardier Service Bulletin 604-57-005, dated September 9, 2014. Bombardier Service Bulletin 605-57-003, dated September 9, 2014. 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. FAA's Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (k)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. Costs of Compliance We estimate that this proposed AD affects 133 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: [[Page 26405]] Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Maintenance or inspection program 1 work-hour x $85 per hour $0 $85 $11,305 revision. = $85. Inspection, identification, 1 work-hour x $85 per hour 33 118 15,694 serialization, and recording. = $85. ---------------------------------------------------------------------------------------------------------------- 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. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
