Post-accident inspection revealed that the helicopter had not been disconnected from the ground power unit (GPU) prior to take off. The company did not have any written procedures regarding the placement or operation of the GPU. On this flight, the GPU had been placed behind the helicopter due to its "proximity to the taxiway." The pilot did not report any mechanical malfunctions or anomalies with the helicopter.
