Models named: P-180. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Baykar Piaggio Aerospace S.p.A. (type certificate previously held by Piaggio Aviation S.p.A.) Model P-180 airplanes, manufacturer serial numbers 1002, 1004 through 1234, and 3001 through 3018, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For airplanes with flexible hydraulic hoses part number (P/N) AS117-04-0205 or P/N 98E0520FAMA000W (landing gear (LG) up and LG down lines); or flexible hydraulic hoses P/N MS8006G207AL or P/N 99G0530FDFD000W (return line) installed: Within 660 hours time-in-service after the effective date of this AD, replace the affected flexible hydraulic hoses in accordance with part 2. B. and 2. C. of the Accomplishment Instructions of Piaggio Aerospace Service Bulletin 80-0497, Revision 0, dated March 5, 2025.
Unsafe condition
This AD was prompted by a report of leakage from the flexible hydraulic hoses connected to the hydraulic pump package (HPP). The FAA is issuing this AD to prevent contact between the flexible hydraulic hoses and the HPP body, which could result in leaks developing in the flexible hydraulic hoses. The unsafe condition, if not addressed, could result in loss of the hydraulic system or fire in the HPP area.
Affected ADs
None.
