Synopsis
A helicopter sustained damage after entering an uncontrolled descent and impacting the ground during a practice flight. The pilot was performing landing and approach maneuvers in an area designated for safe practice. The accident occurred following a takeoff and a subsequent left downwind turn.
Flight Details
According to the pilot, the flight involved practicing landings, climbs, descents, and approaches over a suitable landing area. After landing, the pilot took off and executed a left downwind turn. During the turn, the pilot was attempting to avoid nearby trees.
Pilot Report
The pilot stated that while maneuvering to avoid trees, he climbed too rapidly without sufficient forward airspeed. This condition led to an uncontrolled descent. During the descent, the pilot heard the low main rotor rpm warning horn. He attempted to enter an autorotation but was too close to the ground to complete the maneuver. The helicopter subsequently collided with the terrain.
Accident Sequence
The sequence began with a takeoff from the practice area, followed by a left downwind turn. The loss of control occurred as the helicopter climbed steeply with little forward motion. The uncontrolled descent continued until impact, with the rotor rpm warning sounding during the descent. The pilot’s attempt to recover via autorotation was unsuccessful due to insufficient altitude.
