Officials told ABC 4 News that one man had minor injuries, while another sustained serious injuries.
The crash happened on a runway at the airport located on 2200 North Main Street.
Lt. Brandon Anderson says the pilot was a student and doing a training exercise when the accident occurred.
"He was doing an engine failure simulation and for some reason the helicopter dropped to the ground," says Lt. Anderson
The exercise requires the engine to be shut off and students go through procedures to land the helicopter.
A man who claimed to be the student pilot's cousin says there was time to restart the engine. He says his cousin couldn't start the throttle that disengages a brake like device to straighten out the helicopter and cushion the fall.
The helicopter belonged to Utah Helicopters based in Spanish Fork.
