## Discrepancy

(CAN) DURING GROUND RUN AFTER PERFORMING A FUEL NOZZLE REPLACEMENT, LT ENGINE WAS SET TO TAKEOFF POWER AND PARAMETERS WERE COLLECTED.  AFTER REDUCING THE ENGINE NR 1 POWER WHILE IN PREPARATION TO INCREASE POWER ON ENGINE NR 2, THE TECH HEARD A LOUD BANG AND NOTICED THE ENGINE NR 1 LOOSING SPEED AND ITT DROPPING. THEY SHUTDOWN AND SECURED THE ENGINE NR 1.  A BOROSCOPE INSPECTION WAS CONDUCTED AND NO DAMAGE WAS FOUND ON THE HP AND LP SECTIONS. THE ENGINE WILL BE SENT TO MFG FOR INVESTIGATION AND REPAIR.
