Accident Details
The accident occurred while the helicopter was performing aerial application of agricultural chemicals. The pilot reported a complete loss of engine power as he was turning to reverse direction between swath runs. The failure happened during this maneuver, prompting the pilot to take immediate corrective actions.
Pilot Actions
Upon experiencing the power loss, the pilot returned the helicopter to level flight and entered autorotation. He stated that during the descent, the main rotor rpm was low when he applied collective pitch to cushion the autorotative landing. The helicopter subsequently landed hard.
Landing and Damage
During touchdown, the skid landing gear collapsed, and the helicopter rolled onto its right side. The impact resulted in damage to the landing gear and the airframe.
Post-Accident Examination
After the accident, the engine was examined but no mechanical defects were discovered. The cause of the power loss remains undetermined based on the available evidence.
