NTSB Narrative Summary Released at Completion of Accident

DURING A DUAL INSTRUCTIONAL FLIGHT, THE PILOTS WERE PRACTICING A SIMULATED ENGINE OUT PROCEDURE. ENGINE POWER HAD BEEN REDUCED TO 15' OF MANIFOLD PRESSURE. WHEN AN ATTEMPT WAS MADE TO ADD POWER AT AN ALTITUDE OF ABOUT 500 FT, THE ENGINE QUIT. THE INSTRUCTOR TRIED TO RESTART THE ENGINE, BUT WAS UNSUCCESSFUL. THE INSTRUCTOR SAID THAT DURING THE ATTEMPTED RESTART, THE 'HI' PUMP POSITION WAS SELECTED. ACCORDING TO THE FLIGHT MANUAL, 'ACTUATION OF THE HI FUEL PUMP POSITION, WHEN THE ENGINE IS OPERATING NORMALLY, MAY CAUSE ENGINE ROUGHNESS AND/OR POWER LOSS.' NO PREIMPACT PART MALFUNCTION OR FAILURE WAS FOUND.
