What happened
The aircraft was operating in close proximity to a plowed field when it encountered vegetation along the perimeter. According to the pilot's account, the intention was to execute a landing within the cleared area. During the descent phase, the pilot allowed both the airspeed and the main rotor revolutions per minute (RPM) to decrease significantly.
As the aircraft approached the ground, the pilot observed trees located at the edge of the field. By this point, the loss of energy in the system had become critical. The pilot stated that it was too late to recover from the deteriorating flight condition. The helicopter subsequently flew through the tops of these trees and impacted the plowed field almost vertically.
Upon impact, the aircraft nosed over and came to rest in an inverted position. No further details regarding injuries or specific aircraft registration were provided in the source text.
The investigation
The investigation relied primarily on the pilot's statement regarding the sequence of events. The mechanical condition of the helicopter was not detailed in the available records, but the flight dynamics described indicate a loss of rotor energy during the final approach.
