## Discrepancy

DURING DECENT, THE CREW REPORTED THE LANDING GEAR WOULD NOT EXTEND.  LANDING GEAR CIRCUIT BREAKER TRIPPED.  RESET LANDING GEAR CIRCUIT BREAKER.  GEAR EXTENDED NORMALLY.  RED INTRANSIT LIGHT REMAINED ILLUMINATED.  THE CREW PULLED THE EMERGENCY DOOR CLOSE HANDLE.  THE RED INTRANSIT LIGHT EXTINGUISHED.  AIRCRAFT LANDED NORMALLY.   MAINTENANCE INSPECTED THE GEAR AND FOUND THE WIRING GOING TO THE RIGHT MAIN LANDING GEAR DOWN LOCK SWITCH WAS CHAFED THROUGH THE INSULATION.  MAINTENANCE REPLACED THE RIGHT MAIN LANDING GEAR DOWN LOCK SWITCH AND ASSOCIATED WIRING.  OPS CHECKED SATISFACTORY.  AIRCRAFT WAS RETURNED TO SERVICE.
