Airworthiness Directive · Amendment 39-16865 · Landing gear
Piaggio Aero Industries S.p.A. Airplanes
This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 airplanes, all serial numbers, that are:
(1) Certificated in any category; and
(2) Have any of the following main landing gear (MLG) actuators installed:
(i) Messier-Dowty Part Number (P/N) 114346003 (left hand side): with serial number (S/N) SA0706275, SA0706276, SA0706726, SA0706727, SA0706728, SA0706729, SA0706738, SA0706739,SA0707243, SA0707864, or SA0708072; or

We are adopting a new airworthiness directive (AD) for Piaggio Aero Industries S.p.A. Model P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) Within 25 hours time-in-service (TIS) after December 22, 2011 (the effective date of this AD), inspect both installed MLG actuators to determine if an affected P/N and S/N actuator is installed.
(2) If any affected P/N and S/N actuator is identified with the “P180-32-29” marking on the name plate, no further action is required by this AD on that actuator.
(3) If one or both affected MLG actuators are not identified with the “P180-32-29” marking on the name plate, before reaching a total of 3,000 landings on the actuator or within the next 150 landings after December 22, 2011 (the effective date of this AD), whichever occurs later, replace the affected actuator(s) with serviceable parts following Part B of the Accomplishments Instructions of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin No. 80-0304, dated July 9, 2010. If landing data is not available, the use of a one-to-one landing to flight hour conversion must be applied (example: 3,000 landings equal 3,000 hours TIS).
(4) After December 22, 2011 (the effective date of this AD), do not install any MLG actuator having an affected P/N and S/N, unless it is identified with the “P180-32-29” marking on the name plate.
Note 1: There is a warranty expiration date for the replacement of the actuators. The FAA recommends owners/operators that have affected main landing gear actuators contact the manufacturer immediately and replace the actuators under warranty.
Note 2: This AD differs from the MCAI and/or service information as follows: None.
