[Federal Register Volume 83, Number 131 (Monday, July 9, 2018)] [Proposed Rules] [Pages 31705-31708] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-14506] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0587; Product Identifier 2018-NM-054-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 supersede Airworthiness Directive (AD) 2012-22- 10, which applies to certain 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. AD 2012-22-10 requires repetitive inspections to determine that cotter pins are installed at affected wing-to-fuselage attachment joints and replacement if necessary. Since we issued AD 2012-22-10, we determined that additional nuts of the forward keel beam attachment joint should be inspected, and that repetitive inspections of certain wing-to-fuselage attachment joints are not necessary. This proposed AD would retain the initial inspection of the wing-to-fuselage attachment joints, and remove the repetitive inspections of all but the forward keel beam attachment joint. This proposed AD would also change the repetitive inspection interval for the forward keel beam attachment joint. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by August 23, 2018. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion We issued AD 2012-22-10, Amendment 39-17246 (77 FR 67267, November 9, 2012) (``AD 2012-22-10''), for certain Bombardier, Inc., Model CL- 600-2C10 (Regional Jet Series 700, 701, [[Page 31706]] & 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. AD 2012-22-10 requires repetitive inspections to determine that cotter pins are installed at affected wing-to-fuselage attachment joints and replacement if necessary. AD 2012-22-10 resulted from a report that certain wing-to-fuselage attachment nuts do not conform to the certification design requirements for dual locking features. We issued AD 2012-22-10 to prevent loss of wing-to-fuselage attachment joints, which could result in the loss of the wing. Actions Since AD 2012-22-10 Was Issued Since we issued AD 2012-22-10, we determined that additional nuts of the forward keel beam attachment joint should be inspected, and that repetitive inspections of certain wing-to-fuselage attachment joints are not necessary. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, issued Canadian AD CF-2012-10R1, dated January 22, 2018 (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) 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: The manufacturer has determined that wing-to-fuselage attachment nuts, part number (P/N) SH670-35635-1, SH670-35440-951, SH670-35440- 3, SH670-35635-1, and 95136D-2412, installed at six attachment joint locations, do not conform to the certification design requirements for dual locking features. The nuts are not of the self-locking type as required and do not provide the frictional thread interference required to prevent the nut from backing off the bolt. As a result, only a single locking device, the cotter pin, is provided at these critical joints. In the case where a nut becomes loose, in combination with a missing or broken cotter pin, the attachment bolt at the wing-to-fuselage joint could migrate and fall out. Loss of two attachment joints could potentially result in the loss of the wing. The original version of this [Canadian] AD [which corresponds to FAA AD 2012-22-10] mandated initial and repeat detailed visual inspections (DVIs) of each affected wing-to-fuselage attachment joint to ensure that a cotter pin was installed. Design review and analysis of the inspection findings since the original issue of this [Canadian] AD have led us to determine that additional nuts at the forward keel beam joint should also be included in the inspection and that the repetitive inspection of some wing-to-fuselage attachment joints is not required. This [Canadian] AD maintains the initial inspection requirements [for missing or failed (. . .) cotter pins] for six attachment joint locations, and removes the repetitive inspection requirements for all but the forward keel beam attachment joint. This [Canadian] AD also requires a different repetitive inspection interval, and the [Canadian] AD applicability has been changed for the initial inspection to account for changes made in production. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Service Bulletin 670BA-53-042, Revision B, dated October 20, 2017. This service information describes procedures for detailed inspections of the wing-to-fuselage attachment joints, and of the attachment nuts at the forward keel beam attachment joint for missing or failed cotter pins. 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 these same type design. Costs of Compliance We estimate that this proposed AD affects 274 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 11 work-hours x $85 per hour = $935.......................... $100 $1,035 $283,590 ---------------------------------------------------------------------------------------------------------------- We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. We have no way of determining the number of aircraft that may 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 because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This proposed 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 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. [[Page 31707]] 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. 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: Bombardier, Inc.: Docket No. FAA-2018-0587; Product Identifier 2018- NM-054-AD.
