### ATA 79 Oil – Oil Cooling System Hose - Inspection / Replacement

Manufacturer(s): Piaggio Aero Industries S.p.A.
Applicability: All model P.180 Avanti and P. 180 Avanti II aeroplanes, if equipped with Hose Assembly part number (P/N) 80-337276-001.
Reason: 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 Serv ice 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 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 inst ructions 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.EASA AD No : 2010-0125
