SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2016-11-02, Amendment 39-18529 (81 FR 33371, May 26, 2016) (``AD 2016-11-02''). AD 2016-11-02 applied 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 June 12, 2017 (82 FR 26864). The NPRM was prompted by reports of loose or missing fasteners and collars on the upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. The NPRM proposed to continue to require the repetitive inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair if necessary. The NPRM also proposed to require replacement of affected fasteners, which terminates the inspections. We are issuing this AD to prevent protruding, loose, or missing fasteners, which could result in structural failure of the engine pylons. Transport Canada Civil Aviation (TCCA), which is the aviation authority [[Page 24013]] for Canada, has issued Canadian Airworthiness Directive CF-2016-10R1, dated July 8, 2016 (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: There have been several reported findings of loose or missing Hi-Lite fasteners and collars on the left hand (L/H) and right hand (R/H) upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. Missing fasteners in these areas are shown to significantly reduce the safety margins and could result in a structural failure of the engine pylon. Bombardier, as an interim corrective action issued a new Aircraft Maintenance Manual (AMM) task for detailed inspection of the engine pylon rib and skin fasteners to inspect for protruding, loose or missing fasteners and rectify any discrepancies noted in accordance with a Repair Engineering Order (REO). The original version of this [Canadian] AD, CF-2016-10, mandated the subject inspection and necessary rectification. Bombardier has since issued Service Bulletin (SB) 670BA-54-007 to replace all affected fasteners with interference fit fasteners [including applicable related investigative and corrective actions], as terminating action for the mandated inspection requirement. [Canadian] AD CF-2016-10 is now being revised to mandate compliance with SB 670BA-54-007. Related investigative actions include measurements of the attach holes in the engine pylon upper structure and special detailed visual inspections for cracks in the engine pylon structure. Corrective actions include repair. 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-2017-0530. 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- 0530. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Include Additional Service Information in Credit Paragraph Mesa Airlines suggested that Bombardier Service Bulletin 670BA-54- 007, dated May 13, 2016, be included in paragraph (l), ``Credit for Previous Actions,'' of the proposed AD. The commenter did not provide justification for its request. We infer that the commenter made this request to provide credit for operators that completed the actions in Bombardier Service Bulletin 670BA-54-007, dated May 13, 2016, prior to the effective date of the proposed AD. We do not agree that the commenter's requested change is needed. Paragraph (f) of this AD states that the actions specified in this AD must be accomplished ``unless already done.'' The phrase ``unless already done'' provides credit for accomplishment of the actions required by paragraph (j) of this AD, if done in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-54- 007, dated May 13, 2016, prior to the effective date of this AD. Therefore, we have not changed this AD in this regard. Request To Revise Paragraph (g) of the Proposed AD To Require Airplane Maintenance Manual Task Bombardier requested that Task 54-51-01-220-801, ``Detailed Inspection of the Engine Pylon Rib and Skin Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to Part 2 of the Bombardier CRJ700/900/1000 Aircraft Maintenance Manual (AMM), be required by paragraph (g) of the proposed AD in lieu of Bombardier Temporary Revision (TR) 54-0007, dated March 8, 2016, to the CRJ700/900/1000 AMM. The commenter stated that Bombardier TR 54-0007 was incorporated into Revision 52 of the Bombardier CRJ700/900/1000 AMM, and that the AMM is currently at Revision 56. We partially agree with the commenter's request. We agree to include Task 54-51-01-220-801, ``Detailed Inspection of the Engine Pylon Rib and Skin Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to Part 2 of the Bombardier CRJ700/900/1000 AMM as a method of compliance in paragraph (g) of this AD, but we do not agree to remove Bombardier TR 54-0007, dated March 8, 2016, to the Bombardier CRJ700/900/1000 AMM. We have revised paragraph (g) of this AD to include both Task 54-51-01- 220-801, ``Detailed Inspection of the Engine Pylon Rib and Skin Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to Part 2 of the Bombardier CRJ700/900/1000 AMM, CSP B-001, Revision 56, dated September 25, 2017; and Bombardier TR 54-0007, dated March 8, 2016. This revision provides operators with an option to use either service document to accomplish the required action. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these 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. 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., issued Service Bulletin 670BA-54-007, dated May 13, 2016. This service information describes procedures for replacing fasteners and collars, including applicable related investigative and corrective actions. Bombardier, Inc., also issued Repair Engineering Order 670-54-51- 034, ``Repair for Missing or Loose/Protruding Fasteners in Upper and Lower Pylon Skins FS 1088--FS 1098, PBL 69.3 L & RHS,'' Revision A, dated April 20, 2016. This service information describes procedures for repair, including applicable related investigative and corrective actions. In addition, Bombardier, Inc., issued TR 54-0007, dated March 8, 2016, to the CRJ700/900/1000 AMM; and Task 54-51-01-220-801, ``Detailed Inspection of the Engine Pylon Rib and Skin Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to Part 2 of the Bombardier CRJ700/900/1000 AMM, CSP B-001, Revision 56, dated September 25, 2017. This service information describes procedures for a detailed visual inspection for protruding, loose, or missing fasteners of the left-hand and right-hand upper and lower engine pylons. The content of these documents is nearly identical, except for labels on the figures; we have chosen to incorporate both documents by reference so that either may be used to comply with certain requirements of this AD. 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 273 airplanes of U.S. registry. We estimate the following costs to comply with this AD: [[Page 24014]] Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection (retained from AD 1 work-hour x $85 per $0 $85 per inspection $23,205 per 2016-11-02). hour = $85 per cycle. inspection cycle. inspection cycle. Replacement (new action)....... 43 work-hours x $85 per 1,808 $5,463 per $1,491,399 per hour = $3,655 per inspection cycle. inspection cycle. inspection cycle. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary repairs that will be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these repairs: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Action Labor cost Parts cost Cost per product ---------------------------------------------------------------------------------------------------------------- Repair (retained from AD 2016-11-02) Up to 32 work-hours x $85 (\1\) Up to $2,720. per hour = $2,720. ---------------------------------------------------------------------------------------------------------------- \1\ We have received no definitive data that will enable us to provide cost estimates for the parts cost specified in this AD for the on-condition repairs. 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.
