## Discrepancy

WIRE 1PB2 IN OVERHEAD CIRCUIT BREAKER PANEL WAS FOUND TO HAVE INSULATION CHAFED IN SEVERAL LOCATIONS.  ONE LOCATION IS CHAFED THROUGH EXPOSING THE CONDUCTOR.  A CORRESPONDING CHAFE AREA WAS FOUND JUST BELOW THE AIRFRAME PASS-THROUGH OF THE LT ENGINE POWER LEVER TELEFLEX CABLE. THE PROBLEM WAS CAUSED ROUTING. CORRECTED BY CUTTING OUT DAMAGE AND REROUTE.
