## Analysis

THE PLT REPORTED THAT HE LOST PARTIAL ENGINE POWER DURING CLIMB AND DECIDED TO RETURN TO THE ARPT. HE SAID THE ENGINE CHANGED POWER OUTPUT WHEN HE USED THE ELECTRIC FUEL PUMP BUT HE LEFT IT OFF. DURING FINAL APPROACH, NOT HAVING DECLARED AN EMERGENCY, HE HAD TO DEVIATE TO AVOID ANOTHER ACFT ON THE FINAL APPROACH. WHEN HE WAS REALIGNED HE SAID HE WAS TOO LOW TO REACH THE RWY. DURING POST ACCIDENT INVESTIGATION THE ENG PERFORMED NORMALLY.
