## Probable cause

The pilot's failure to maintain directional control during landing which resulted in the wing striking the ground during the inadvertent ground loop.

## Sequence of events

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

- Loss of control - on ground/water, landing
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent
- On ground/water encounter with terrain/water, landing
  - terrain condition - ground

## Analysis

The airplane was substantially damaged during an aborted landing.  The student pilot reported that he had returned from a cross country flight and then refueled and returned to the active runway to perform some touch and go landings.  He reported that upon his final landing, the airplane touched down and veered to the right.  He stated that he attempted to go-around and the right wheel made contact with the dirt adjacent to the runway turning the airplane sharply to the right.  He reported that the left wingtip contacted the ground and he closed the throttle and the airplane came to a complete stop.  The pilot did not report any malfunction of the airplane.
