## 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
  - touch-and-go - initiated, pilot in command
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
- Nose down, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE PLT WAS PRACTICING TOUCH-&-GO LANDINGS & LOST CONTROL OF THE ACFT. IT SWERVED TO THE LEFT ONTO SOFT TERRAIN & WENT OVER ON ITS NOSE. AT 1ST, THE PLT MADE COMMENTS ABOUT IMPROPER STRUT INFLATION. HOWEVER, LATER, HE REPORTED THAT WX WAS NOT A PROBLEM & THAT HE WAS JUST NOT AS QUALIFIED AS HE HAD THOUGHT.
