AD 2025-23-08

The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. Model 182Q and 182R airplanes. This AD was prompted by reports of damaged intercooler inlet and outlet hoses. This AD requires repetitive visual inspections of the intercooler inlet and outlet hoses for cracks and, at a certain compliance time or if any cracks are found, replacement of the intercooler inlet and outlet hoses. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD 2025-0230-E, dated October 21, 2025 (EASA Emergency AD 2025-0230-E) (also referred to as the MCAI), to correct an unsafe condition on Textron Aviation Inc. Model 182M, 182N, 182P, 182Q, 182R, all serial numbers, and (Reims-manufactured) F182P and F182Q airplanes, all serial numbers, if modified in accordance with EASA Supplemental Type Certificate (STC) 10013975 at Revision 15 or earlier, or (formerly) STC EASA.A.S.00774 (installation of Engine SMA SR305-230 or SR305-230E); and Model 182Q, 182R, all serial numbers, if modified in accordance with EASA STC 10016495 at Revision 1 or earlier, or (formerly) STC EASA.IM.A.S.02857, (installation of Engine SMA SR305-230/-230-1). The MCAI states that occurrences were reported of damaged intercooler air hoses. The MCAI also states that EASA Emergency AD 2025-0230-E is considered an interim action and further AD action may follow. This condition, if not detected and corrected, could result in a loss of manifold pressure and consequent loss of engine power, potentially leading to a forced landing, damage to the airplane, and injury to occupants. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2025-4001. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed SMA Aero Engines GmbH Service Bulletin SB-C182-71-011, Revision No. 01, dated October 20, 2025, which specifies procedures for repetitive visual inspections of the intercooler inlet and outlet hoses for cracks and specifies replacement of any intercooler air hose found cracked. 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. FAA's Determination These products have been approved by the civil 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, that authority has notified the FAA of the unsafe condition described in the MCAI and material referenced above. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. AD Requirements This AD requires accomplishing the actions specified in the material already described. Differences Between This AD and the MCAI The MCAI applies to certain Textron Aviation Inc. Model 182M, 182N, 182P, 182Q, 182R and (Reims-manufactured) F182P and F182Q airplanes. This AD does not apply to Models 182M, 182N,182P, and (Reims-manufactured) F182P and F182Q airplanes because EASA STC 10013975 is currently not validated in the United States. 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. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because damaged intercooler inlet and outlet hoses could result in a loss of manifold pressure. The consequent loss of engine power could lead to a forced landing, damage to the airplane, and injury to occupants, and thus an inspection of these parts is required before further flight. In addition, most of the affected airplanes have already accumulated or are approaching 500 flight hours and thus the mandatory replacement is required either before further flight or within 50 flight hours of operation. These compliance times are shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 10 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs Action Labor cost Parts cost Cost per product Cost on U.S. operators Visually inspect intercooler inlet and outlet hoses 1 work-hours × $85 per hour = $85 $0 $85 $850 Replace intercooler inlet and outlet hoses 1 work-hours × $85 per hour = $85 356 441 4,410 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, and (2) Will not affect intrastate aviation in Alaska.
