Aircraft involved
Probable cause & findings
The pilot's inadvertent dynamic rollover during takeoff.
Factual narrative
The commercial pilot of the helicopter was transporting equipment in support of remote mining activities using a 100-foot long-line. During takeoff, and while preparing to lift the external sling load, he inadvertently allowed the helicopter to drift laterally to the right and the right skid struck the ground, resulting in a dynamic rollover. The helicopter continued to roll to the right, and the main rotor blades struck the ground. The helicopter subsequently came to rest on its right side, sustaining substantial damage to the main rotor drive system, fuselage, and tail boom. The pilot sustained minor injuries, and reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
