What was found
(CAN) A FUEL BOOST PUMP WAS REPLACED FOR ITS SCHEDULED OVERHAUL REPLACEMENT AT 3500 HOURS.A WIRE WAS FOUND CHAFED TO BARE WIRE THROUGH ROUGHLY MIDWAY OF THE MANUFACTURER SUPPLIED HARNESS. THIS COULD HAVE THE POTENTIAL TO IGNITE THE FUEL TANK IF SPARKS WERE PRESENT. DUE TO THE LENGTH OF WIRE, IT IS POSSIBLE FOR THE HARNESS TO RUB ON A COUPLE OF DIFFERENT PLACES, IE: BONDING STRAP, RIB, TOP OF PUMP. PILATUS WAS CONTACTED WITH THE PROBLEM AND WE REQUESTED A MEANS TO PROTECT THE HARNESS.
