## Discrepancy

DURING THE 100HR INSPECTION ON N210SU, WE FOUND THAT BOTH FUEL CAPS YET AGAIN HAD DEFORMED INTERNAL GASKET AFTER BEING NEWLY INSTALLED FOR ONLY 99.2 HOURS.  REMOVED AND REPLACED BOTH FUEL CAPS WITH NEW P/N C156003-0101 (8130-3).  THE FUEL VENT LINE UNDER THE LEFT WING WAS FOUND TO BE 1/4 INCH LOWER THAN THE ALIGNMENT CALLED OUT FOR IN THE CESSNA/TEXTRON 172 SERIES (1996 & ON) AMM AND WAS CORRECTED PER CHAP. 28-20-00.
