Analysis 

The solo student pilot reported that he configured the airplane for takeoff and that, during the takeoff roll, the airplane reached 55 knots and ascended about 5 ft above ground level. The airplane descended back onto the runway and veered right. He applied left rudder and pulled the throttle to idle as the airplane exited the right side of the runway. He leveled the wings and locked the brakes, and the airplane impacted a fence. The airplane sustained substantial damage to both wings. The student reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's failure to attain sufficient airspeed to climb out of ground effect, which resulted in a descent, loss of directional control, runway excursion, and impact with a fence.

Findings

Aircraft
Airspeed - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Student pilot (Cause)

Environmental issues

  1. How often should a student pilot fly?
    "6 hours (Pilot In Command, all aircraft), 9.8 hours (Last 90 days, all aircraft), 6.7 hours (Last 30 days, all aircraft)"
    As the student's endorsement on their pilot certificate never expires, the original logbook make and model endorsement expires after 90 days. In reality, flying multiple solo flights a week is a must to retain any level of consistency, and building toward one's private the flight exam.

  2. Yeah 33 hours is well into student time and one should be past learning the basics like soft field practice takeoffs - assuming that's what he was doing here. Wonder how long he was a student solo before this accident. Also I wonder if he raised the flaps out of habit after liftoff into ground effect. That would obviously send it back to the ground alarmingly, but I'm at a loss why he lost directional control unless there was a tire blown - variable winds were reported to be very light. Of course he could have also still had right rudder into when it smacked back down as per normal for P-factor takeoff operations.

  3. Late afternoon in late October on runway 23. Could the sun have been in his eyes and played a part in this? I'm trying to be kind because otherwise it looks as though this guy simply isn't cut-out to fly. Destroying a perfectly serviceable C172 on take-off in perfect conditions takes some doing.
