FOR FURTHER INFORMATION CONTACT : Joseph Catanzaro, Aerospace Engineer, Airframe and Propulsion Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516–228–7366; email 9-avs-nyaco-cos@faa.gov . SUPPLEMENTARY INFORMATION : Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain De Havilland Aircraft of Canada Limited Model DHC–8–400, –401, and –402 airplanes. The NPRM published in the Federal Register on September 9, 2022 (87 FR 55322). The NPRM was prompted by AD CF–2020– 01, dated January 14, 2020, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states it was reported that electrical bonding jumpers had been installed on fuel scavenge lines even after the removal was required by Transport Canada AD CF–2010–31, dated September 3, 2010 (which corresponds to FAA AD 2011– 13–06, Amendment 39–16729 (76 FR 37258, June 27, 2011) (AD 2011–13– 06)). Subsequent investigation showed that electrical bonding jumpers may have been installed in production or in service at other locations on the fuel scavenge and vent lines. If installed, these electrical bonding jumpers could affect the integrity of the fuel scavenge and vent lines’ electrical bonding paths, which may lead to lightning strike induced fuel tank ignition. In the NPRM, the FAA proposed to require an inspection for electrical bonding jumpers and brackets on the fuel scavenge and vent lines at specific wing locations, and if installed, removal or modification of those jumpers and brackets. The FAA also proposed to require a records check to determine if certain maintenance tasks were performed and removal, modification, or rework if those tasks were performed. The FAA also proposed to prohibit the use of earlier versions of certain maintenance tasks. The FAA is issuing this AD to address altered electrical bonding paths, which may lead to lightning strike-induced ignition of the fuel tank. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1151. Discussion of Final Airworthiness Directive Comments The FAA received a comment from the Air Line Pilots Association, International (ALPA) who supported the NPRM without change. The FAA received additional comments from Horizon Air. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Remove Job Access and Close-up Requirements Horizon Air requested revising paragraphs (h)(1) and (2) of the proposed AD to remove the Job Set-up and Close-Out sections of the Accomplishment Instructions of Bombardier Service Bulletins 84–28–29 and 84–28–30, both dated October 17, 2018, from the requirements of the proposed AD. Horizon Air asserted that incorporating the Job Set-up and Close Out sections of the Accomplishment Instructions do not address the unsafe condition and also restrict an operator’s ability to perform other maintenance in conjunction with the incorporation of the service bulletins. In this case, the FAA agrees with the commenter’s request to exclude the ‘‘Job Set-up’’ and ‘‘Close Out’’ sections of Bombardier Service Bulletin 84–28–29; and 84–28–30; both dated October 17, 2018. The FAA has revised paragraphs (h)(1) and (2) of this AD to require accomplishment of paragraph 3.B., ‘‘Procedure,’’ of the Accomplishment Instructions of Bombardier Service Bulletins 84–28–29; or 84–28–30; both dated October 17, 2018; as applicable. Request To Correct Typographical Errors Horizon Air requested correction of some typographical errors it found in paragraphs (h)(1) and (2) of the proposed AD. Horizon Air noted that the dates provided for the referenced service bulletins was published in the NPRM as October 1 instead of October 17 in two places. Horizon Air also pointed out that in paragraph (h)(2) of the proposed AD, the first reference to a service bulletin seems to be in error and should be 84–28–30 instead of 84– 28–29. The FAA acknowledges the typographical errors and agrees to the request. Paragraphs (h)(1) and (2) of this AD have been revised as requested. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 De Havilland Aircraft of Canada Limited has issued Bombardier Service Bulletins 84–28–29; and 84–28–30; both dated October 17, 2018; which describe procedures for an inspection of certain wing stations in the left and right wings for the presence of brackets and electrical bonding jumpers on the fuel scavenge and vent lines, and if installed, removal or modification of those electrical bonding jumpers and brackets. These documents are distinct because they apply to different airplane configurations. De Havilland Aircraft of Canada Limited has also issued the following Bombardier service information, which describes fuel system limitations, critical design configuration control limitations (CDCCLs), or airworthiness limitations for fuel tank systems.

The FAA has received no definitive data on which to base the cost estimates for the on-condition rework specified in this AD. 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. The FAA is 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 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) Will not affect intrastate aviation in Alaska, and (3) 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.
