NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE ACFT OWNER WAS TAKING MEL TRAINING FOR A CLASS RATING. HE STATED THAT THE CFI TOLD HIM TO NOT USE THE AUX ELECTRIC FUEL PUMPS DURING TAKEOFF, A PROCEDURE IN CONTRADICTION TO THE FLIGHT MANUAL. DURING THE TAKEOFF GROUND ROLL, THE STUDENT SAID THE RIGHT ENGINE QUIT AT A SPEED JUST BELOW ROTATION. THE CFI ASSUMED CONTROL OF THE ACFT AND CONTINUED THE TAKEOFF, LOST CONTROL OF THE ACFT AND LANDED IN A FIELD OFF THE DEPARTURE END OF THE RUNWAY. THE STUDENT SAID THE ACFT WAS HALFWAY DOWN THE 3,400 FT RUNWAY WHEN THE ENGINE QUIT. THE FLIGHT MANUAL LISTS VMC AS 82 MPH, AND, VYSE AS 109 MPH. THE TAKEOFF AND LANDING GROUND ROLL DISTANCE CHARTS IN THE FLIGHT MANUAL STATE THAT 960 FEET IS REQUIRED TO ACCELERATE TO 86 MPH, AND 650 FT IS REQUIRED TO DECELERATE FROM THAT SPEED. EXAM OF THE ACFT REVEALED THAT THE RIGHT PROPELLER WAS NOT FEATHERED, AND NO REASON WAS FOUND FOR THE RIGHT ENGINE POWER LOSS.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE FAILURE OF THE INSTRUCTOR PILOT (PILOT IN COMMAND) TO REJECT THE TAKEOFF AFTER THE LOSS OF POWER ON ONE ENGINE WHEN SUFFICIENT RUNWAY REMAINED TO STOP THE AIRCRAFT. CONTRIBUTING TO THE ACCIDENT WAS THE DISREGARD OF THE AIRCRAFT MANUAL, FAILURE TO USE THE FUEL BOOST PUMP AND EXCEEDING THE AIRCRAFT SINGLE ENGINE PERFORMANCE CAPABILITY.
