## Probable cause

THE POOR IN FLIGHT DECISION OF THE PILOT TO FLY NEAR THUNDERSTORMS AND THEIR ASSOCIATED TURBULENCE RESULTING IN AN UNCONTROLLED DESCENT AND IN FLIGHT COLLISION WITH TERRAIN.

## Sequence of events

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

- In flight encounter with weather, cruise - normal
  - weather condition - turbulence(thunderstorms)
  - flight into known adverse weather - intentional, pilot in command (cause)
  - in-flight planning/decision - poor, pilot in command (cause)
- Loss of control - in flight, cruise - normal
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT FLYING THE HOMEBUILT AIRPLANE ENCOUNTERED SEVERE TURBULENCE NEAR A THUNDERSTORM AND LOST CONTROL IN FLIGHT. THE AIRPLANE THEN DESCENDED UNCONTROLLED TO THE GROUND.
