Narrative:

The student and I were in an small aircraft. We taxied onto runway 36 after calling unicom and checking traffic. The student stopped on the runway to check all engine gauges and flight instruments to ensure everything was for a go. He pushed the throttle full forward and we accelerated for about 5-10 seconds to reach an IAS first officer approximately 40-50 KTS. I, as the instrument pulled the left mixture for the student to do an aborted takeoff. The student failed to retard the throttles and had no idea what was happening. He kept his hand on the throttles in the full forward position and also applied brakes. The aircraft yawed left and he applied brakes harder. The brakes locked up and we skidded sideways off the runway into the mud. I tried pushing on the right rudder when the aircraft yawed to the left. The student was twice my size and I could not move the rudder pedal at all. As the aircraft slipped into the mud the right engine propeller struck the side of the runway. After a short time I shut down the engine. There was a scrape on one end of the propeller and the other end was curled forward about 3/4'. This end was also cracked. The propeller was refurbished and no engine damage was done. Make sure that if a student seems preoccupied and states it that fact not to fly with them. We had discussed single engine aborts before the flight and had already done one abort prior to the accident. Someone then anonymously reported this to the FAA. I was called by the local FSDO and stated to them that 'I had nothing to say.'

Title: EXPECTING THE STUDENT TO ACCOMPLISH AN ABORTED TKOF PROC THE REPORTER SHUT DOWN THE LEFT ENGINE AT RELATIVELY SLOW SPEED ON TKOF. INSTEAD THE STUDENT ATTEMPTED TO CONTINUE THE TKOF RESULTING IN THE ACFT LEAVING THE RWY CAUSING SOME MINOR DAMAGE.

Narrative: THE STUDENT AND I WERE IN AN SMA. WE TAXIED ONTO RWY 36 AFTER CALLING UNICOM AND CHKING TFC. THE STUDENT STOPPED ON THE RWY TO CHK ALL ENG GAUGES AND FLT INSTRUMENTS TO ENSURE EVERYTHING WAS FOR A GO. HE PUSHED THE THROTTLE FULL FORWARD AND WE ACCELERATED FOR ABOUT 5-10 SECS TO REACH AN IAS FO APPROX 40-50 KTS. I, AS THE INSTR PULLED THE LEFT MIXTURE FOR THE STUDENT TO DO AN ABORTED TKOF. THE STUDENT FAILED TO RETARD THE THROTTLES AND HAD NO IDEA WHAT WAS HAPPENING. HE KEPT HIS HAND ON THE THROTTLES IN THE FULL FORWARD POS AND ALSO APPLIED BRAKES. THE ACFT YAWED LEFT AND HE APPLIED BRAKES HARDER. THE BRAKES LOCKED UP AND WE SKIDDED SIDEWAYS OFF THE RWY INTO THE MUD. I TRIED PUSHING ON THE RIGHT RUDDER WHEN THE ACFT YAWED TO THE LEFT. THE STUDENT WAS TWICE MY SIZE AND I COULD NOT MOVE THE RUDDER PEDAL AT ALL. AS THE ACFT SLIPPED INTO THE MUD THE RIGHT ENG PROP STRUCK THE SIDE OF THE RWY. AFTER A SHORT TIME I SHUT DOWN THE ENG. THERE WAS A SCRAPE ON ONE END OF THE PROP AND THE OTHER END WAS CURLED FORWARD ABOUT 3/4'. THIS END WAS ALSO CRACKED. THE PROP WAS REFURBISHED AND NO ENG DAMAGE WAS DONE. MAKE SURE THAT IF A STUDENT SEEMS PREOCCUPIED AND STATES IT THAT FACT NOT TO FLY WITH THEM. WE HAD DISCUSSED SINGLE ENG ABORTS BEFORE THE FLT AND HAD ALREADY DONE ONE ABORT PRIOR TO THE ACCIDENT. SOMEONE THEN ANONYMOUSLY RPTED THIS TO THE FAA. I WAS CALLED BY THE LCL FSDO AND STATED TO THEM THAT 'I HAD NOTHING TO SAY.'
