## Discrepancy

ELECTRIC POWER WIRES CHAFED INTO BLEED AIR TUBE CAUSING BLEED AIR LEAK.  BREAKERS DID NOT POP.  WIRE NR'S P10616, LT FEEDER; P105A6 RT FEEDER; P96F6, LT AVIONICS; P95G6 RT AVIONICS.  ALL 4 WIRES WELDED THEMSELVES TO BLEED TUBE AT STA 130. CHECKED ANOTHER C-441; WIRES WERE ROUTED DIFFERENTLY.  SUBMITTER SUSPECTED OTHER C-441'S WILL HAVE SOME PROBLEM.
