He was scheduled for his first flight lesson on the day of the accident. The instructor told the student pilot to wait for him and not to touch anything. While waiting for the flight instructor, the student pilot started the aircraft, ran it up to full rpm, and then began to increase the collective pitch control. The helicopter climbed vertically to a high hover and the pilot lost control. He received minor injuries.
