On September 3, 2006, about 0915 central daylight time, a Cessna 172N, N1210F, registered to Randall, Henry E Trustee and operated by Ferguson Aviation Academy, impacted trees at the Ferguson Airport, Pensacola, Florida, while on a Title 14 CFR Part 91 instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The student pilot received minor injuries and the airplane incurred substantial damaged. The flight had originated about 5 minutes before from the same airport. The instructor stated that he had been working with the student pilot that morning in preparation for the student's first solo flight. Upon completion of dual instruction, he instructed the student to perform full stop landings. He was going to be in communication with the student with a hand held radio during the solo takeoffs and landings. He went to the approach end of runway 36 to observe the student. The first takeoff and landing were uneventful. During the second landing, on short final, it appeared the airplane was slightly high. The airplane then seemed to assume a flared attitude appropriate for landing but well above the runway. He heard power applied partially to slow the descent, followed by full power, consistent with initiating a go around. He did not observe the airplane climb in altitude, so he radioed the student for 20 degrees of flap. About that time the student initiated a left turn, barely clearing trees on the west side of the runway. He was unable to radio better instructions as he observed the aircraft maintain 30-50 feet of altitude in the turn, then descend below the tree line, followed by an impact sound. The student pilot stated that he had been practicing takeoffs and landings with his flight instructor for about an hour and the instructor felt that he was ready to conduct his first solo takeoffs and landings. The instructor made the proper endorsement in his pilot's logbook before permitting him to go solo. His first takeoff and landing were uneventful. During the second landing, he felt the airplane was too high and fast. He applied full engine power and attempted to turn left with 40 degrees of flap. He heard his instructor on the airport's Unicom frequency, telling him to select for 20 degrees of flap. He attempted to select 20 degrees of flap; however he saw the trees in front of him. The airplane impacted the top of the tree before coming to a stop on the ground. The student pilot stated there were no mechanical failures or malfunctions to the airplane or any of its systems prior to the accident.
