Incident Overview
An on-demand air taxi helicopter was involved in an accident while attempting to depart from a confined area. The helicopter had previously landed on a narrow dirt road that was in close proximity to boulders and other obstructions. After the passengers boarded, the pilot initiated a liftoff to a hover.
Sequence of Events
During the liftoff maneuver, the helicopter's lift skid made contact with a boulder. This contact resulted in the pilot losing control of the aircraft. The helicopter subsequently struck the terrain and came to rest against a commercial building.
Context
The landing site was a confined area characterized by its narrow dimensions and the presence of nearby obstacles, including boulders. The pilot had successfully landed there before the passengers boarded, but the environment posed challenges during the departure phase.
Outcome
The helicopter came to rest against a commercial building after the loss of control. The source does not specify any injuries or damage to the helicopter or building beyond the fact that the aircraft struck terrain and the building.
