Accident Overview
A commercial pilot was conducting a personal flight with a single passenger when the helicopter experienced an abnormal sequence of events during takeoff. As the helicopter lifted to a two-foot hover, a low rotor warning activated. The helicopter then turned slowly 90 degrees to the north before rapidly rotating 720 degrees. During the subsequent landing attempt, the helicopter bounced, impacted the terrain, and rolled over. Both the pilot and passenger were uninjured.
Weight and Environmental Factors
The combined weight of the pilot, passenger, and fuel on board exceeded the helicopter's maximum takeoff gross weight. Additionally, wind conditions at the accident site were reported as 280 degrees at 13 knots, gusting to 19 knots. These environmental conditions may have influenced the helicopter's behavior during the low-altitude maneuver.
Sequence of Events
The takeoff attempt began with the helicopter lifting to a hover. Almost immediately, the low rotor warning sounded, indicating a potential loss of rotor rpm. The helicopter then yawed unintentionally, first a slow 90-degree turn to the north, followed by a rapid 720-degree rotation. The pilot attempted to land, but the helicopter bounced, struck the ground, and rolled onto its side.
Post-Accident Observations
No injuries were sustained by the occupants. The accident highlights the importance of adhering to weight limitations and being aware of gusty wind conditions during low-speed, low-altitude operations. However, no causal factors beyond the stated weight exceedance and wind conditions are provided in the source.
