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 was prompted by reports that non-conforming FIREX squib wire harness connectors may have been installed, which could result in FIREX squib wire harness connectors being connected to the wrong FIREX bottle connectors on affected aircraft. This AD requires a visual inspection of the connections between the FIREX squib wire harness connectors and FIREX bottle connectors, installation of split ring lanyards on the FIREX squib wire harness connectors, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective December 10, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 10, 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 July 6, 2018 (83 FR 31491). The NPRM was prompted by reports that non-conforming FIREX squib wire harness connectors may have been installed, which could result in FIREX squib wire harness connectors being connected to the wrong FIREX bottle connectors on affected aircraft. The NPRM proposed to require a visual inspection of the connections between the FIREX squib wire harness connectors and FIREX bottle connectors, installation of split ring lanyards on the FIREX squib wire harness connectors, and corrective actions if necessary. We are issuing this AD to address this wiring discrepancy, which, in the event of an engine fire, could result in misrouting the supply of fire extinguishing agent to the wrong engine, or limit the supply from both FIREX bottles to only one engine, which could result in the inability to extinguish an engine fire. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2018-08R1, dated March 2, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700- 1A11 airplanes. The MCAI states: Bombardier Inc. has been made aware that non-conforming squib connector wire harnesses may have been installed on one of the two engine FIREX bottle installations on some of the affected aeroplanes. The subject non conformity of squib connector wire [[Page 55250]] length can allow cross connection between the two squib connectors on one of the engine FIREX bottles, preventing proper function of the engine FIREX system. In the event of an engine fire, this wiring discrepancy may potentially misroute the supply of fire extinguishing agent to the wrong engine, or limit the supply from both FIREX bottles to only one engine, hence impacting the operational safety of the aeroplane. Bombardier Inc. issued service bulletins (SB) 700-26-011, 700- 26-5003, 700-26-6003, and 700-1A11-26-004, for the affected model aeroplanes, to address the potentially unsafe condition caused by the non-conforming FIREX bottle squib connector wiring. The original version of this [Canadian] AD was issued to mandate compliance with the above-mentioned SBs, as applicable. Revision 1 of this [Canadian] AD is issued to correct an error in the applicability section of the original AD. 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- 0585. 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 Refer to Revised Service Information Bombardier requested that the NPRM be updated to reference the current revision of certain service information to avoid issuing an Alternate Means of Compliance (AMOC) following the release of this AD. Bombardier noted that four service bulletins referred to in the NPRM have been revised. Bombardier stated that the latest revisions correct a minor error in the original weight and balance section. Bombardier also noted that a previous revision to the service information included mention of the Canadian AD CF-2018-08R1, as well as a clarifying note in the close-out instruction of the service information for operator convenience and ease of use. We agree with the commenter's request. Because the revised service information does not include any additional actions, we have updated the preamble and figure 1 to paragraph (g) of this AD to refer to the revised service information. Bombardier also requested that we revise the NPRM to include previous revisions of the service information as credit for operators who have already accomplished the required actions to avoid issuance of AMOCs following the release of this AD. We agree with the commenter's request. Because the previous revisions of the service information do not include any additional actions, we have revised paragraph (h) of this AD to provide credit for actions accomplished prior to the effective date of this AD using the applicable Bombardier service information identified in paragraphs (h)(1) through (h)(12) of this AD. 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, Inc. issued the following service information: Bombardier Service Bulletin 700-1A11-26-004, Revision 03, dated August 24, 2018. Bombardier Service Bulletin 700-26-011, Revision 03, dated August 24, 2018. Bombardier Service Bulletin 700-26-5003, Revision 03, dated August 24, 2018. Bombardier Service Bulletin 700-26-6003, Revision 03, dated August 24, 2018. This service information describes procedures for a visual inspection of the connections between the FIREX squib wire harness connectors and the FIREX bottle connectors to determine whether the connectors are installed correctly, and installation of split ring lanyards on the FIREX squib wire harness connectors. This service information also describes procedures for reconnecting incorrectly installed connectors to the appropriate mating connectors and an operational test of the fire extinguishing system. These documents are distinct since they apply to different airplane models in different configurations. 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 358 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/Modification............ 2 work-hours x $85 per hour $55 $225 $80,550 = $170. ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some or 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 known 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, [[Page 55251]] 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.
