## Discrepancy

FOUND CHAFED WIRE THAT HAD BEEN ARCING ON THE BOX THAT SURROUNDS THE BOOST PUMPS TO KEEP THE FUEL IN THE FUEL HOPPER. ABOUT SIX INCHES FROM WHERE THE BOOST PUMP, CONNECTOR PLUG ENTERS THE INBOARD RIB OF THE WET WING AREA, A WIRE (THE RED WIRE) HAD BEEN CHAFING ON THE BOX AND CHAFED THROUGH THE INSULATION. A PIN HOLE WAS CREATED IN THE CAN FROM THE ELECTRICAL ARCING.
