What happened
The aircraft experienced a rollover incident during an attempted takeoff sequence. Prior to this event, the pilot had executed a landing specifically to deplane a passenger. Upon concluding the passenger disembarkation, the pilot initiated the takeoff procedure.
During the initial phase of the takeoff roll, one of the helicopter's skids became embedded in the soft terrain beneath it. Despite recognizing that the skid was stuck, the pilot continued to apply takeoff power in an effort to lift off. The aircraft responded by pulling up and subsequently rolling over onto its side or roof.
The investigation
Post-incident analysis focused on the interaction between the landing gear and the ground surface. Investigators determined that the soft nature of the terrain was a primary factor in the immobilization of the skid. The mechanical systems of the aircraft were examined, but the root cause was identified as environmental rather than mechanical failure.
Findings
The pilot acknowledged during the investigation that he should have been more aware of the hazards associated with the specific terrain conditions. The decision to continue applying power despite the skid being stuck contributed directly to the rollover. This incident highlights the critical importance of assessing ground conditions before attempting takeoff, particularly in unprepared or soft surfaces.
Safety message
Pilots must carefully evaluate terrain conditions prior to takeoff. If landing gear becomes immobilized due to soft ground, continuing to apply power may result in loss of control or structural damage. Pilots should be prepared to abort the takeoff if obstacles or terrain issues prevent a safe departure.
