AD 2025-12-02 ACTIVE

The FAA is adopting a new airworthiness directive (AD) for certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. This AD was prompted by reports of unexpected rearward movement of pilot and co-pilot seats during take-off and landing. This AD requires a one-time visual inspection of each affected seat, accomplishment of applicable corrective actions, and operational tests. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Background The Civil Aviation Authority (CAA), which is the aviation authority for the United Kingdom (UK), has issued UK CAA AD G-2025-0002, dated April 11, 2025; corrected April 25, 2025 (UK CAA AD G-2025-0002) (also referred to as the MCAI), to correct an unsafe condition on certain Ipeco pilot and co-pilot seats. The MCAI states that occurrences were reported of unexpected rearward movement of pilot and co-pilot seats during take-off and landing. Investigations originally determined that horizontal guide block wear, presence of burrs on horizontal center track, and horizontal track lock system weakness (spring tension too low) were causes which contributed to the seat not being correctly locked. The original unsafe condition was addressed through UK CAA AD G-2022-0011, dated June 9, 2022, (which corresponds with FAA AD 2023-14-10, Amendment 39-22510, dated August 3, 2023 (88 FR 51230) (FAA AD 2023-14-10)). However, the incorrect distribution of the stops and packers during the modification required by FAA AD 2023-14-10 has been found to cause the seat not to positively lock in position because of the unequal re-installation of the stops and packers onto the fore/aft tubes during seat reassembly, which can result in unexpected rearward movement of pilot and co-pilot seats during take-off and landing. The FAA is issuing this AD to address the unsafe condition on these products, which, if not corrected, could lead to further cases of unwanted flight crew seat movement, which could result in reduced control of the airplane, a rapid descent of the airplane, and serious injury to passengers and crew. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2025-1101. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Ipeco Service Bulletin 063-25-20, Issue 1, dated March 25, 2025. This material describes procedures to conduct a one-time visual inspection of each affected seat, and if any incorrect installation is found (stops or packers), remove and install the stops and packers, and perform operational tests of the seats. 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 Ipeco material described previously. See "Differences Between This AD and the MCAI" for a discussion of the general differences included in this AD. Differences Between This AD and the MCAI UK CAA AD G-2025-0002, dated April 11, 2025; corrected April 25, 2025, does not mention Part C of the Accomplishment Instructions of Ipeco Service Bulletin 063-25-20, Issue 1, dated March 25, 2025. This AD, however, requires the accomplishment of Part C of the Accomplishment Instructions of Ipeco Service Bulletin 063-25-20, Issue 1, dated March 25, 2025. The FAA has coordinated this change with the UK CAA. 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 movement of the pilot and co-pilot seats during take-off and landing could result in reduced control of the airplane, a rapid descent of the airplane, and serious injury to passengers and crew. Additionally, the compliance time in this AD is 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 120 appliances installed on, but not limited to, ATR-GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 $0 $170 $20,400 The FAA estimates the following costs to do any necessary on-condition action 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 this on-condition action: Estimated Costs of On-Condition Actions Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 $420 $505 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.
