The student pilot said that he was returning to Rogers, Minnesota, when he heard a "pop" and then the helicopter yawed left. The student pilot said that he lost pedal control and entered a turning autorotation. He said that at approximately 35 feet above the ground, he introduced some aft cyclic in an attempt to perform a run on landing. He said that the helicopter "spun violently to [the] right". The student pilot said he added full left [control pedal] and down cyclic. The helicopter dropped to the ground. An examination of the helicopter's belt drive system revealed that the lower shaft bearing in the secondary drive unit to the tail rotor was loose and the tail rotor drive belt had come off.

On May 16, 2001, at 1110 central daylight time, a Parker Rotorway 162F helicopter, N311RM, operated by a student pilot, sustained substantial damage when it impacted into a field 15 miles northwest of Minneapolis, Minnesota, during an emergency landing. Prior to the emergency landing attempt, the helicopter experienced a tail rotor malfunction. Visual meteorological conditions prevailed at the time of the accident.

A Federal Aviation Administration inspector examined the helicopter at the student pilot's residence. The inspector observed that both skids were collapsed, the tail boom was bent upward, the bottom vertical stabilizer was crushed upward, and the tail rotor was bent aft. Control continuity was confirmed. An examination of the helicopter's belt drive system revealed that the lower shaft bearing in the secondary drive unit to the tail rotor was loose and the tail rotor drive belt had come off.
