What happened
The accident occurred while a pilot was attempting to launch a helicopter from a flatbed trailer. During the initial phase of the lift-off, the pilot reported that the right rear skid felt unusually heavy. In response to this sensation, he applied left cyclic control input to level the aircraft.
Once the helicopter became airborne, the pilot applied left pedal. This input caused the helicopter to turn sharply to the left. During this maneuver, the aircraft struck a parked pickup truck located nearby on the ground.
The investigation
The source text does not provide details regarding mechanical inspections or post-accident examination of the helicopter components.
Findings
The sequence of events indicates that the pilot's corrective inputs during the critical lift-off phase from an elevated platform contributed to the loss of control. Specifically, the combination of left cyclic and subsequent left pedal application resulted in a leftward turn that led to contact with the stationary vehicle.
