What happened
The incident occurred while an aerial application helicopter was attempting to lift off from a helipad mounted on a trailer. As the rotorcraft began its ascent, a gust of wind originating from behind struck the aircraft. This sudden force caused the helicopter to lurch forward unexpectedly.
During this forward movement, the toe of the right skid became snagged under a toolbox located on the helipad surface. In an effort to free the skid and disengage it from the obstruction, the pilot attempted to adjust the aircraft's position. However, the maneuver resulted in the helicopter setting down off-center relative to the pad.
Consequently, the aircraft slipped off the edge of the helipad. The impact caused substantial damage to the helicopter itself. Additionally, the helipad sustained minor damage from the event.
