The helicopter sustained substantial damage to the main rotor system, transmission structural support, and the tail rotor drive shaft. The pilot stated that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation. Additionally, the pilot stated that he had not flown the helicopter during the previous 2 months, and that the accident might have been prevented had he flown the helicopter more frequently.
