What was found
FOUND FUEL LINE, PN 1500106-151, CHAFED AGAINST THROTTLE CABLES , PROP CONTROL CABLES BELOW THROTTLE. THIS LINE PROVIDES FUEL PRESSURE TO THE 2 MANUAL ENGINE PRIMER PUMPS AT THE BASE OF THE QUADRANT. HAD THIS LINE CHAFED THROUGH, FUEL UNDER PRESSURE WOULD HAVE FLOWED INTO THE AIRPLANE CABIN. THE ONLY WAY TO SHUT OFF FUEL FLOW TO THIS LINE WOULD BE TO CLOSE THE FRONT ENGINE FUEL SELECTOR VALVE, AND SHUT DOWN THE FRONT ENGINE. THIS IS A POTENTIAL HAZARDOUS CONDITION AND COULD CAUSE AN INFLIGHT CABIN FIRE WITH RESULTANT LOSS OF LIFE AND AIRCRAFT IF NOT FOUND AND CORRECTED. (K)
