What happened
Shortly after liftoff, the pilot encountered significant downdrafts and variable wind gusts. The pilot decided to set the helicopter back down approximately 100 yards from the point of takeoff. Hovering proved very difficult under these conditions, and the helicopter settled onto upsloping terrain. The aircraft slid to the right, down the slope, and rolled over. A fire erupted from the engine after impact, destroying the helicopter.
The investigation
The investigation focused on the immediate environmental factors and mechanical response during the incident. The pilot reported that hovering was extremely difficult due to the weather conditions. The helicopter's movement was influenced by the terrain, sliding to the right and rolling over before the fire began.
Findings
The primary contributing factor was the variable wind gusts and downdrafts encountered shortly after takeoff. These conditions made hovering difficult and led to the loss of control as the aircraft settled on the upsloping terrain. The helicopter was destroyed by impact and subsequent fire.
Safety message
Pilots should be aware of the potential for downdrafts and variable wind gusts in certain terrain conditions, which can make hovering difficult and lead to loss of control.
