PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO P-180 Airplanes
This AD applies to PIAGGIO AERO INDUSTRIES S.p.A. Model PIAGGIO P-180 airplanes, all serial numbers, that are:
(i) Equipped with hose assembly, part number (P/N) 80-337276-001; and
(ii) Certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. 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 the next 150 hours time-in-service (TIS) after the November 18, 2010 (the effective date of this AD) and repetitively thereafter at intervals not to exceed 165 hours TIS after the last inspection, inspect the left-hand (LH) and the right-hand (RH) engine mounted fuel heater for wear damage and minimum clearance. Do the inspections following Part A of the Accomplishment Instructions in PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N.: 80-0175, Rev. N. 1, dated May 14, 2010.
(2) If any wear damage to either the LH or the RH fuel heater or to the oil cooling system hose is detected during any inspection required in paragraph (f)(1) of this AD, before further flight after the inspection, replace both hose assembly P/Ns 80-337276-001 with a new hose assembly P/N 80-337284-001. Do the replacements following Part B of the Accomplishment Instructions in PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N.: 80-0175, Rev. N. 1, dated May 14, 2010. Installing both the LH and the RH hose assembly P/N 80-337284-001 terminates the repetitive inspections required in paragraph (f)(1) of this AD.
(3) If no wear damage to the fuel heater or to the oil cooling system hose is detected, but insufficient clearance is found during any inspection required in paragraph (f)(1) of this AD, within the next 660 hours TIS after the inspection, replace the LH and RH hose assembly P/N 80-337276-001 with a new hose assembly P/N 80-337284-001. Do the replacements following Part B of the Accomplishment Instructions in PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N.: 80-0175, Rev. N. 1, dated May 14, 2010. Installing both the LH and the RH hose assembly P/N 80-337284-001 terminates the repetitive inspections required in paragraph (f)(1) of this AD.
(4) You may terminate the repetitive inspections required in paragraph (f)(1) of this AD by replacing both the LH and the RH hose assembly P/Ns 80-337276-001 with a new hose assembly P/N 80-337284-001 at any time after the initial inspection required in paragraph (f)(1) of this AD, as long as no wear damage to the fuel heater or to the oil cooling system hose is detected and sufficient clearance is found.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
