Probable cause
The failure of the pilot-in-command to maintain recommended main rotor RPM following a reported total loss of engine power due to undetermined reasons, during a practice autorotation resulting in a hard landing and subsequent roll over.

Read the full NTSB narrative
The helicopter landed hard and rolled over after the certified flight instructor (CFI) attempted to recover from a simulated autorotative descent. According to the CFI, as he attempted to level off at 75 to 100 feet above the ground, the helicopter yawed sharply to the left along with a loss of main rotor rpm, and despite his efforts to recover, the helicopter touched down left skid low. The engine was later placed in a test cell and when started operated to approximately 2,550 rpm instead of 2,700 rpm. The No. 3 cylinder was noted to only have 5 psi during the differential compression test. Further examination of the No. 3 cylinder by the cylinder manufacturer revealed discolorations which are typical of high temperature operations; wear on the exhaust valve seating face and exhaust valve guide was noted.
