Accident Overview
The aircraft owner was undergoing multi-engine training for a class rating. According to the student, the certified flight instructor (CFI) instructed him not to use the auxiliary electric fuel pumps during takeoff, a procedure that contradicted the flight manual.
Sequence of Events
During the takeoff ground roll, the student reported that the right engine quit at a speed just below rotation. The aircraft was approximately halfway down the 3,400-foot runway at that time. The CFI assumed control of the aircraft and continued the takeoff. Subsequently, the CFI lost control of the aircraft and landed in a field off the departure end of the runway.
Aircraft Performance Data
The flight manual specifies Vmc (minimum control speed) as 82 mph and Vyse (best single-engine rate of climb speed) 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 feet is required to decelerate from that speed.
Examination Findings
Examination of the aircraft revealed that the right propeller was not feathered. No reason was found for the right engine power loss.
