## Discrepancy

WHEN CLEARED FOR TAKEOFF ON FLIGHT 9492, THE CREW ADDED POWER FOR TAKEOFF THEY HEARD AN ODD SOUND FROM THE LEFT ENGINE. IT SOUNDED LIKE A MUFFLED SHOTGUN BLAST. THE CREW ABORTED TAKEOFF AND TAXIED BACK TO THE GATE WITH NO FURTHER INCIDENT. THE ITT AND PROP RPM VARIED UP AND DOWN ON THE TAXI IN. ON SHUTDOWN THE LEFT ENGINE MADE A LOUD VACUUM CLEANER SOUND. MAINTENANCE REMOVED AND REPLACED THE ENGINE. TEARDOWN REPORT WILL BE AVAILABLE AT A LATER DATE.
