What to do
Operators of affected Piaggio P.180 Avanti and Avanti II aeroplanes must replace the specified affected flexible hoses with serviceable parts within 660 flight hours from 19 May 2025, the effective date of the directive. They must also ensure that no affected parts are installed on any aircraft after modification or from the effective date for aircraft without affected parts. Maintenance teams should follow the instructions in Piaggio Aero Industries Service Bulletin 80-0497 for the replacement procedure.
Summary
EASA Airworthiness Directive 2025-0102 is an airworthiness directive addressing hydraulic power landing gear flexible hoses on Piaggio Aviation P.180 Avanti and Avanti II aeroplanes, specifically those with manufacturer serial numbers 1002, 1004 to 1234, and 3001 to 3018. The directive mandates modification of the landing gear hydraulic flexible hoses to prevent potential leakage and fire hazards. It applies to specific part numbers of flexible hoses used in the landing gear hydraulic system.
What changed
This new airworthiness directive introduces a mandatory replacement of affected flexible hoses with improved serviceable parts on the specified Piaggio P.180 aircraft. It prohibits the reinstallation of the affected hoses and requires compliance within 660 flight hours from the effective date. The directive is based on findings that electrical arcing caused punctures in the hydraulic hoses due to improper installation and a failure in the hydraulic pump package electrical motor.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk that could lead to hydraulic fluid leaks or fire in the hydraulic pump area, potentially compromising the landing gear system. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent in-service failures. Compliance also ensures adherence to European Union aviation safety regulations and avoids operational restrictions.
