ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD [[Page 52141]] was prompted by a report of cracking at the fastener holes of the left- hand-side support bracket of the elevator bell crank for the control linkage in the vertical stabilizer. This AD requires an eddy current inspection on certain support brackets of the elevator bell crank for any cracking at the fastener holes, a measurement to confirm that the fastener hole diameters are within tolerance, and replacement with a new support bracket of the elevator bell crank if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective November 20, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 20, 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 certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the Federal Register on May 8, 2018 (83 FR 20745). The NPRM was prompted by a report of cracking at the fastener holes of the left-hand-side support bracket of the elevator bell crank for the control linkage in the vertical stabilizer. The NPRM proposed to require an eddy current inspection on certain support brackets of the elevator bell crank for any cracking at the fastener holes, a measurement to confirm that the fastener hole diameters are within tolerance, and replacement with a new support bracket of the elevator bell crank if necessary. We are issuing this AD to address any cracking in the support bracket of the elevator bell crank, which could lead to detachment of the bracket and loss of functionality of the elevator on the affected side, and result in reduced controllability of the airplane. Failure of both brackets could result in loss of pitch control of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2017-32, dated October 10, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition on certain Bombardier, Inc., Model BD-700-1A10 and BD-700- 1A11 airplanes. The MCAI states: During a repair on an aircraft in-service, cracking was observed at the fastener holes of the left hand side elevator bell crank support bracket for the control linkage in the vertical stabilizer. Further investigation confirmed the presence of similar cracking on other aircraft on both the left and right hand side brackets. An investigation found that the fastener holes on some brackets did not conform to the required tolerance and fastener installation resulted in fastener hole cracks. This [Canadian] AD requires an inspection of both elevator bell crank support brackets, and replacement if they are found cracked or do not meet the required fastener hole tolerance. Left unrepaired, cracking of an elevator bell crank support bracket could lead to detachment of the bracket and loss of functionality of the elevator on the affected side, resulting in reduced controllability of the aircraft. Failure of both brackets could result in loss of pitch control of the aircraft. 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-2018- 0397. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Incorporate the Latest Service Information Bombardier requested that we revise the NPRM to incorporate the latest service information. Bombardier stated that Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018, corrects a typographical error made to the affected airplane serial number listing. Bombardier also requested that we add Bombardier Service Bulletin 700-27-5009, Revision 01, dated July 18, 2017, to the ``Credit for Previous Actions'' paragraph. We agree with the commenter's request. We have revised paragraph (g) of this AD to incorporate Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018, for accomplishing the actions in this AD. Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018, revises the effectivity to include an airplane already included in the applicability of this AD, and includes minor edits that do not affect the scope of this AD. We have also revised paragraph (h) of this AD to include Bombardier Service Bulletin 700-27-5009, Revision 01, dated July 18, 2017. Request To Clarify a Certain Serial Number NetJets requested that we clarify the omission of a certain serial number in the service information. NetJets commented that serial number 9732 is specified in the applicability paragraph of the NPRM, but it is not specified in Bombardier Service Bulletin 700-27-5009, Revision 01, dated July 18, 2017; or Bombardier Service Bulletin 700-27-6009, Revision 01, dated July 18, 2017. We agree to provide clarification for the commenter. Serial number 9732 is not specified in the effectivity of Bombardier Service Bulletin 700-27-5009, Revision 01, dated July 18, 2017; or Bombardier Service Bulletin 700-27-6009, Revision 01, dated July 18, 2017, but Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018, adds serial number 9732 to the effectivity. As we stated previously, we have revised this AD to include Bombardier Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018, for accomplishing the actions in this AD. Serial number 9732 was previously included in paragraph (c) of this AD, and the applicability of an AD takes [[Page 52142]] precedence over the effectivity listed in any service information. Therefore, the actions in this AD is required for the airplane having serial number 9732, regardless of what service information is specified in this AD. We have not changed the AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for addressing 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 final rule. Related Service Information Under 1 CFR Part 51 Bombardier has issued Service Bulletin 700-27-5009, Revision 02, dated June 15, 2018; and Service Bulletin 700-27-6009, Revision 01, dated July 18, 2017. This service information describes an eddy current inspection on certain support brackets of the elevator bell crank for any cracking at the fastener holes, a measurement to confirm that the fastener hole diameters are within tolerance, and replacement with a new support bracket of the elevator bell crank. These documents are distinct since they apply to different airplane models. 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 109 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection and measurement......... 10 work-hours x $85 per $19 $869 $94,721 hour = $850. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacement that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need this replacement: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement........................... 2 work-hours x $85 per hour = $170...... $4,798 $4,968 ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 and associated appliances to the Director of the System Oversight Division. Regulatory Findings 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.
