## Discrepancy

DESCENDING THROUGH 18,000 FEET, LOST RIGHT MAIN AC BUS, GENERATOR WOULD NOT RESET.  BUS REMAINED OFF FOR REMAINDER OF FLIGHT.  APU GENERATOR WOULD NOT POWER BUS.  PASSENGERS REPORTED SPARKS FROM RIGHT ENGINE WHEN LIGHTS WENT OUT.  A SHORTED IDG FEEDER CABLE ON THE RIGHT ENGINE CAUSED THE RIGHT MAIN AC BUS TO SHORT THE CIRCUIT BREAKER.  THE FEEDER CABLE WAS REPAIRED AND REPOSITIONED TO PREVENT FURTHER CHAFING.
