 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2024-2413; Project Identifier MCAI-2023-00982-A]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain DAHER AEROSPACE (DAHER) Model TBM 700 airplanes. This proposed AD was prompted by certain existing emergency procedures in the pilot's operating handbook (POH) that cannot be fully accomplished since certain equipment cannot be disconnected by the pilot(s) from the flight deck. This proposed AD would require revising the POH for your airplane to provide the flight crew with corrected emergency procedures. The FAA is proposing this AD to address the unsafe condition on these products.
 DATES: The FAA must receive comments on this NPRM by December 9, 2024.
 ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: *Federal eRulemaking Portal:*

Submissions containing CBI should be sent to Fred Guerin, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2023-0164, dated August 18, 2023 (also referred to as the MCAI), to correct an unsafe condition on certain serial-numbered DAHER Model TBM 700 airplanes. The MCAI states that the emergency procedures “Cabin Electrical Fire or Smoke During flight” and “Smoke elimination” cannot be fully accomplished since certain equipment cannot be disconnected by the pilot(s) from the flight deck. The MCAI requires incorporating a temporary revision (TR) into the emergency procedures section of the applicable POH, informing all flight crews, and operating the airplane accordingly. This condition, if not corrected, could lead to increased flight crew workload during critical phases of flight, resulting in reduced control of the airplane. To address the unsafe condition, DAHER published Temporary Revision 30, dated July 2023 (DAHER TR 30), to Section 3, Emergency Procedures, which removes the procedures “Cabin Electrical Fire or Smoke During Flight” and “Smoke elimination” of the DAHER Model TBM 960 Pilot's Operating Handbook, Edition 0, dated January 27, 2022, and replaces them with the new emergency procedure “Fire or Smoke in Flight”. The FAA is proposing 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-2024-2413. Related Material Under 1 CFR Part 51 The FAA reviewed DAHER TR 30 to Section 3 of the Emergency Procedures section of the POH by removing the procedures “Cabin Electrical Fire or Smoke During Flight” and “Smoke elimination” and replacing them with the new emergency procedure “Fire or Smoke in Flight.” 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. Clarification of Relationship Between DAHER TR 30 and the Proposed AD Applicability Although the applicability of this proposed AD is certain serial-numbered DAHER Model TBM 700 airplanes, the TR that needs to be inserted into the applicable POH for the owner/operator's airplane is Temporary Revision 30, dated July 2023, to DAHER Pilot's Operating Handbook TBM 960, Edition 0, dated January 27, 2022. The FAA type certificate data sheet (TCDS) specifies Model TBM 700 airplanes, but the notes in the FAA TCDS indicate that, depending on the airplane's serial number and any optional modification installed, an affected Model TBM 700 airplane could have a trade name that includes a “900” designation, including TBM 900, TBM 910, TBM 930, TBM 940, or TBM 960. FAA's Determination These products have been approved by the aviation authority of another country and are 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 and material referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require revising the existing POH for your airplane to provide the flight crew with emergency procedures to follow under certain conditions, except as discussed under “Differences Between this Proposed AD and the MCAI.” The owner/operator (pilot) holding at least a private pilot certificate may revise the existing POH for your airplane and must enter compliance with the applicable paragraph of this proposed AD into the airplane maintenance records in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The pilot may perform this action because it only involves revising the POH. This action could be performed equally well by a pilot or a 
                    ( print page 84840)
                    mechanic. This is an exception to the FAA's standard maintenance regulations. Differences Between This Proposed AD and the MCAI EASA AD 2023-0164 includes requirements to “inform all flight crews and, thereafter, operating the airplane accordingly” and this proposed AD would not specifically require those actions because those actions are already required by FAA regulations. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 930 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: Estimated Costs

 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 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a “significant regulatory action” under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
