Accident Details
According to the pilot, during a takeoff from a dolly, the helicopter pitched nose-down, contacted the ground, and the landing skids collapsed. The pilot reported no mechanical malfunctions or anomalies with the helicopter.
Post-Accident Findings
A post-accident inspection determined that the helicopter had not been disconnected from the ground power unit (GPU) prior to the takeoff. The company operating the helicopter had no written procedures regarding the placement or operation of the GPU. In this instance, the GPU had been positioned behind the helicopter due to its proximity to the taxiway.
Operator Procedures
The absence of written protocols for GPU placement and operation was noted. The GPU's location behind the helicopter was a result of operational constraints, but no specific guidance existed for its use during ground operations.
