## Discrepancy

(CAN) DURING FLIGHT,  THE ENGINE DOES NOT ACCELERATE PROPERLY WHEN THE AIR CONDITIONING SYSTEM IS ON, AND WHEN THE AIR CONDITIONING SYSTEM IS OFF THE ENGINE REACTS NORMALLY TO THE POWER LEVER MOVEMENT. TROUBLESHOOTING SHOWED THE ISSUE WAS RESOLVED WHEN THE FCU WAS REPLACED. THE ORIGINAL FCU WILL BE SENT FOR INVESTIGATION.
