## Discrepancy

DURING INSPECTION, AN 8 GAGE DC POWER DISTRIBUTION CABLE WAS FOUND TO HAVE CHAFED AND ARCING AGAINST A RELAY.  THIS CABLE IS ENCLOSED BEHIND A PANEL AND DIRECTLY ADJACENT TO A SHROUDED FUEL CROSSFEED LINE, AND CABIN OUTFLOW VALVES.  SHOULD A FIRE START, IT IS POSSIBLE THAT IT COULD GO UNNOTICED UNTIL THE CROSSFEED SHROUD AND LINE IS BREACHED.
