## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - remedial action - inadequate, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll

## Analysis

THE PILOT REPORTED THAT WHILE ON FINAL APPROACH FOR LANDING, THE AIRPLANE WAS HIGH. WHEN THE AIRPLANE TOUCHED DOWN, IT BOUNCED. AFTER THE AIRPLANE TOUCHED DOWN AGAIN, IT VEERED TO THE LEFT AND ACCORDING TO THE PILOT, HE 'GAVE TOO MUCH RUDDER.' THE AIRPLANE STARTED TO GROUND LOOP AND THE PILOT 'JAMMED DOWN ON THE RIGHT BRAKE, INSTEAD OF BOTH BRAKES.' THE LEFT WING CONTACTED THE SURFACE AS THE AIRPLANE GROUND LOOPED.
