## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL ON LANDING. THE PILOT'S LACK OF FAMILIARITY WITH THIS TYPE AIRPLANE (LARGE TIRES/TAIL WHEEL COMBINATION), AND HIS LACK OF TOTAL EXPERIENCE WERE CONTRIBUTING FACTORS.

## 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)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - lack of total experience, pilot in command (contributing factor)
- Nose over, landing - roll

## Analysis

THE PILOT STATED THAT HE LOST DIRECTIONAL CONTROL AND NOSED OVER SHORTLY AFTER LANDING ON A HARD SURFACED RUNWAY WITH LARGE 'TUNDRA' TIRES. THE PILOT HAD LIMITED EXPERIENCE IN FLYING A TAIL WHEEL AIRPLANE WITH THESE LARGE TIRES, WHICH WERE DESIGNED PRIMARILY FOR OFF AIRPORT USE IN ROUGH TERRAIN.
