## Probable cause

PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL UPON LANDING AND SUBSEQUENT PREMATURE ROTATION OF THE AIRPLANE DURING THE GO-AROUND ATTEMPT. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S LACK OF TOTAL EXPERIENCE.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - flare/touchdown
  - directional control - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - go-around - attempted, pilot in command
  - rotation - premature, pilot in command (cause)
- Loss of control - in flight, go-around (vfr)
  - stall - encountered, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE STUDENT PILOT WAS PRACTICING TOUCH-AND-GO LANDINGS DURING HIS FIRST UNSUPERVISED SOLO FLIGHT. AFTER HIS THIRD OR FOURTH LANDING, THE AIRPLANE VEERED TO THE LEFT AND TOWARDS A HANGAR. HE INITIATED A GO-AROUND AND ROTATED PREMATURELY, STALLING THE AIRPLANE. THE AIRPLANE COLLIDED WITH THE GROUND IN A NOSE LOW ATTITUDE. THE PILOT STATED THAT THERE WERE NO MECHANICAL PROBLEMS WITH THE AIRPLANE.
