## Discrepancy

(CAN) WHILE CONDUCTING TRAINING FLIGHTS, AN ACFT REPORTED ELECTRICAL PROBLEMS DURING LANDING. GROUND INSP REVEALED THAT THE BATTERIES WERE DEAD. MX WAS DISPATCHED FOR REPAIRS. FURTHER INVESTIGATION FOUND RT ALTERNATOR DRIVE BELT LOOSE AND LT ALTERNATOR UNSERVICEABLE.  MX REPLACED THE BATTERY AND LT ALTERNATOR. THE RT ALTERNATOR DRIVE BELT WAS ALSO ADJUSTED.  THE ACFT WAS RETURNED TO SERVICE.
