## Discrepancy

HRO - FLT 1310 - DURING TAKEOFF, ENGINE FIRE WARNING LIGHT CAME ON AT APPROXIMATELY 60 KNOTS.  THE CREW ABORTED THE TAKEOFF AND THE FIRE WARNING LIGHT WENT OUT WHEN POWER WAS REDUCED.  THE AIRCRAFT RETURNED TO THE GATE.  A FIVE INCH CRACK WAS FOUND IN THE COMBUSTION PLENUM CHAMBER ABOVE THE P3 TAPPING PORT ALLOWING P3 AIR TO ACTIVATE THE FIRE WARNING SENSORS.  COMBUSTION CASE FAILED.  ENGINE WAS REMOVED AND REPLACED.  TEAR DOWN REPORTS WILL FOLLOW AS THEY ARE AVAILABLE.  (X)
