## Discrepancy

THIS AIRCRAFT IS EQUIPPED WITH OPTIONAL INBOARD FUEL FILLER CAPS.  THE FUEL FILLER CAP ADAPTER ASSY. (P/N C156005-0105) HAS A SPRING LOADED FLAPPER WHICH IS DEPRESSED BY THE FUEL DISPENSING NOZZLE WHILE FILLING THE TANK.  THE FLAPPER HAS BEEN HITTING ON THE (P/N 2600101-48) VENT LINE ASSY INSIDE THE TANK BAY AND HAS WORN THE VENT LINE APPROXIMATELY HALF WAY THROUGH ITS DIAMETER.  DEFECT WAS DISCOVERED BECAUSE FUEL FILLER ADAPTER WAS REMOVED FOR MAINTENANCE.
