FOR FURTHER INFORMATION CONTACT : Todd Thompson, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 206–231–3228; email Todd.Thompson@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 all Deutsche Aircraft GmbH (Type Certificate previously held by 328 Support Services GmbH; AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328–100 and 328–300 airplanes. The NPRM published in the Federal Register on December 6, 2023 (88 FR 84764). The NPRM was prompted by AD 2023–0137, dated July 12, 2023 (EASA AD 2023–0137) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that operators reported findings of damaged affected parts. The extent of the detected damage of the affected parts did not ensure that appropriately low electrical impedance is obtained and maintained through the affected bonding path. The unsafe condition, if not detected and corrected, could lead to the loss of bonding function and, in combination with a lightning strike, create a source of ignition in a fuel tank, possibly resulting in a fire or explosion. In the NPRM, the FAA proposed to require a one-time detailed inspection of each affected part, and applicable corrective actions, as specified in EASA AD 2023–0137. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–2230. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. 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 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 EASA AD 2023–0137 specifies procedures for a one-time detailed inspection of each affected part for worn and ruptured bonding straps, and applicable corrective actions (replacing the affected parts). This material 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. Interim Action The FAA considers that this AD is an interim action. If final action is later identified, the FAA might consider further rulemaking then. Costs of Compliance The FAA estimates that this AD affects 35 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: VerDate Sep<11>2014 16:07 Mar 11, 2024 Jkt 262001 PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 E:\FR\FM\12MRR1.SGM 12MRR1 khammond on DSKJM1Z7X2PROD with RULES

17724 Federal Register / Vol. 89, No. 49 / Tuesday, March 12, 2024 / Rules and Regulations E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 44 work-hours × $85 per hour = $3,740 ..................................................................................... $0 $3,740 $130,900 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: The FAA has received no definitive data on which to base the cost estimates for the on-condition actions 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.

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 Airbus Canada Limited Partnership Model BD–500–1A11 airplanes. The NPRM published in the Federal Register on August 31, 2023 (88 FR 60160). The NPRM was prompted by AD CF–2023–08, dated February 13, 2023, issued by Transport Canada, which is the aviation authority for Canada (Transport Canada AD CF– 2023–08) (also referred to as the MCAI). The MCAI states that a manufacturing molding issue with an electrical connector may prevent the connector from self-locking. The connector may become loose over time, preventing the charging of EPSUs 3 and 4 and lead to the loss of emergency lights, possibly resulting in injury to occupants during an evacuation. In the NPRM, the FAA proposed to require removing the affected connector, installing a new connector, and testing the EPSUs, as specified in Transport Canada AD CF–2023–08. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1810. Discussion of Final Airworthiness Directive Comments The FAA received a comment from Delta Air Lines (DAL). The following presents the comment received on the NPRM and the FAA’s response. Request To Specify No U.S.-Registered Airplanes DAL stated that via the FAA U.S. registry, the four affected airplanes are not U.S.-registered. The FAA assumes Delta would like the AD to specify no U.S.-registered airplanes. The FAA agrees that the affected airplanes are not registered in the United States. The Costs of Compliance section of the final rule has been changed accordingly. 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 comment 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, and any other changes described previously, 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 Transport Canada AD CF–2023–08 specifies procedures for removing the affected connector, installing a new connector, and testing the EPSUs.
