## Discrepancy

DURING A DUAL LESSON AT 2500MSL THE AIRCRAFT EXPERIENCED A POWER INTERRUPTION. FOLLOWING THE CHECKLIST, THE ELECTRICAL FUEL PUMP WAS TURNED ON WHICH RESTORED NORMAL POWER IMMEDIATELY. THE FLIGHT RETURNED TO KLOT WITHOUT FURTHER INCIDENT. UPON INSPECTION OF THE AIRCRAFT IT WAS DETERMINED THAT THE ENGINE DRIVEN FUEL PUMP WAS THE SOURCE OF INTERRUPTION.
