What happened
The accident occurred while a certified flight instructor (CFI) was conducting a demonstration of wind effect management during turns around a point. The helicopter was operating at an approximate altitude of 200 feet above ground level (AGL). As the aircraft was turned downwind, it began to descend unexpectedly. The descent continued until the right skid made contact with the terrain, causing the helicopter to roll over.
The investigation
Post-accident examination confirmed that the right skid had contacted the ground during the maneuver. No mechanical failures or pre-accident anomalies were reported that would have prevented normal operation of the aircraft systems.
Findings
The primary contributing factor was the strong, gusty winds present at the time of the accident. These conditions likely exceeded the helicopter's performance capabilities during the low-altitude maneuver, leading to an uncontrolled descent and subsequent rollover. The pilot's decision to continue the demonstration in such weather conditions played a significant role in the outcome.
Safety message
Pilots should exercise extreme caution when performing maneuvers around a point in strong gusty winds. Low-altitude operations require precise control inputs and adequate energy management, particularly when transitioning from upwind to downwind headings where wind shear effects can be pronounced.
