## Sequence of events

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

- On ground/water encounter with terrain/water, taxi - from landing
  - terrain condition - sand bar (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)
- Nose over, taxi - from landing

## Analysis

THE PILOT DECIDED TO LAND IN THE LAKE APPROXIMATELY 1000 YDS FROM THE SEA PLANE BASE AND WAS ATTEMPTING A STEP-TAXI BACK TO THE BASE WHEN THE ACFT STRUCK A SAND BAR. THE PILOT STATED THAT HE WAS TAXIING NEAR TALL GRASS WHERE HE THOUGHT THE WATER WAS DEEP ENOUGH TO TAXI ON, WHEN THE AIRCRAFT STRUCK THE SAND BAR. THE PILOT DID NOT NOTICE THE SAND BAR PRIOR TO BEGINNING HIS TAXI. AFTER THE AIRCRAFT STRUCK THE SAND BAR IT NOSED OVER TO AN INVERTED ATTITUDE IN THE WATER.
