According to Piaggio Aero Industries Service Bulletin 80-0175 Rev 01, if a flexible hose P/N 80-337276-001 has to be replaced, also the other one (on the opposite nacelle) shall be replaced with a new one, P/N 80-337284-001 (refer to Step 15 of SB accomplishment instructions).
Replacing both of the flexible hoses with new one's is required to terminate the repetitive inspections on aircraft.
I suggest to specify that, when accomplishing instructions detailed in section f(2), f(3) and f(4), both the flex hoses have to be replaced with new design one's.
As long as at least one flexible hose P/N 80-337276-001 is installed, repetitive inspection has to be carried out.
Thanks in advance and best regards
