ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Baykar Piaggio Aerospace S.p.A. (type certificate previously held by Piaggio Aviation S.p.A.) (Piaggio) Model P-180 airplanes. This AD was prompted by a report of leakage from the flexible hydraulic hoses connected to the hydraulic pump package (HPP). This AD requires replacing the affected flexible hydraulic hoses. This AD also prohibits installing the affected flexible hydraulic hoses on any airplane. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective February 17, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 17, 2026. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2025-2272; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the mandatory continuing airworthiness information (MCAI), any comments received, and other information.

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 Piaggio Model P-180 airplanes. The NPRM was published in the Federal Register on September 5, 2025 (90 FR 42862). The NPRM was prompted by AD 2025-0102, dated May 5, 2025 (EASA AD 2025-0102) (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 leakage from the flexible hydraulic hoses was reported on a Model P-180 airplane. A subsequent investigation revealed that the failure of the HPP electrical motor caused an anomalous current to return through the HPP body, resulting in electrical arcing. This arcing, which occurred as the HPP body was in contact with a flexible steel braided hose, punctured the flexible hydraulic hose. Additionally, the improper installation of the HPP, specifically the incorrect routing…
