He landed on a portable dolly in order to move the helicopter into a hanger for parking. He landed at an angle on the dolly and elected to reposition the helicopter. The dolly was chocked on a 2 to 3-degree down slope. He increased the collective pitch and the dolly started moving.

Examination of the crash site revealed the helicopter came to rest on its right side about 50 feet from the dolly. The tail boom had separated as well as the tail rotor and main rotor blades. Ground scars were located on the ground behind the helicopter where the tail rotor blades had collided with the ground. In addition, ground scars were present on the ground where the main rotor blades collided with the ground.
