## Probable cause

THE PILOT'S EXCESSIVE DESCENT AND LACK OF FAMILIARITY WITH THE AIRCRAFT.  CONTRIBUTING TO THE ACCIDENT WAS THE SOFT CONDITION OF THE SAND BAR.

## Sequence of events

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

- Nose over, landing - roll
  - terrain condition - soft (contributing factor)
  - descent - excessive, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (cause)

## Analysis

THE PILOT RECENTLY UPGRADED FROM A CESSNA 180 AIRPLANE TO A CESSNA 206 AIRPLANE.  HE HAD NOT LANDED THE CESSNA 206 AIRPLANE ON THIS SAND BAR BEFORE, ONLY THE CESSNA 180.  HE STATED HE LANDED A LITTLE 'HOT' AND AFTER PASSING THE RIVER BANK HE 'CUT' HIS THROTTLE TO IDLE.  THE AIRPLANE LANDED HARD AND BOUNCED INTO THE AIR.  UPON TOUCHING DOWN THE SECOND TIME, THE AIRPLANE NOSED OVER.  EXAMINATION OF THE NOSE GEAR STRUT ASSEMBLY SHOWED NO MECHANICAL DIFFICULTIES.
