A Training Captain was conducting an Operational Proficiency Check (OPC); the pilot under training was required to demonstrate a clear area rejected takeoff. The helicopter was equipped with a Training Idle System (TIS) which was in use to simulate a failure of the left engine. The helicopter took off along Runway 16 at Aberdeen; at about 28 kt the commander simulated a failure of the left engine and the takeoff was rejected. The pilot flared the helicopter to reduce speed and descended towards the runway. As the collective control lever was raised to reduce the rate of descent, the overspeed protection system shut down the right engine. Rotor rpm (rrpm) decayed rapidly and the helicopter touched down firmly before rrpm could be restored. The right engine freewheel unit had failed causing that engine to overspeed; this was contained by the overspeed protection system shutting down the engine. Four Safety Recommendations are made.
