## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE DURING THE LANDING. THE CROSSWIND CONDITION WAS A FACTOR RELATED TO THE ACCIDENT.

## 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
  - weather condition - crosswind (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Nose over, landing - roll

## Analysis

THE PLT WAS LANDING ON RWY 28. HE ESTIMATED THE WINDS WERE FROM 210 DEG AT 15 KTS. THE LANDING APPEARED NORMAL UNTIL THE LEFT WING STARTED TO RISE. THE PLT SAID HE DID NOT 'GET ON THE RUDDER QUICK ENOUGH' AND THE AIRPLANE STARTED TO GROUNDLOOP TO THE LEFT. THE PLT SAID HE 'PROBABLY HIT BRAKES NEAR EDGE OF RWY, CAUSING PLANE TO NOSE OVER.'
