2010-21-09 PIAGGIO AERO INDUSTRIES S.p.A: Amendment 39-16469; Docket No. FAA-2010-0736; Directorate Identifier 2010-CE-035-AD. Effective Date (a) This airworthiness directive (AD) becomes effective November 18, 2010. Affected ADs (b) None. Applicability (c) 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. Subject (d) Air Transport Association of America (ATA) Code 79: Engine Oil. Reason (e) The mandatory continuing airworthiness information (MCAI) states: A damaged fuel heater caused a fuel leakage in the engine nacelle; investigation revealed that the damage to the fuel heater was due to chafing with an oil cooling system hose. Piaggio Aero Industries (PAI) issued Service Bulletin (SB) 80- 0175, which was applicable to all aeroplanes and contained instructions for a repetitive inspection of the affected parts and, if necessary, their replacement and/or for the repositioning of oil/ fuel tubing if minimum clearances were not found. ENAC of Italy issued PA 2002-335 to require the accomplishment of these corrective actions. Later on, PAI introduced a new Hose Assembly (P/N 80-337284- 001), which allows better clearances and removes the problem of potential interference. PAI issued SB 80-0175 Revision 1, limiting the applicability to aeroplanes with the old P/N installed only and giving instructions for the replacement with the new Hose Assembly P/N. This new AD, which supersedes ENAC Italy PA 2002-335, is issued to grant the revised applicability and to include an optional terminating action, which consists in replacing the Hose Assembly P/ N 80-337276-001 with the new P/N 80-337284-001. Actions and Compliance (f) 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.
