## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL TO AVOID THE HIGH VEGETATION.  FACTORS RELATING TO THIS ACCIDENT WERE THE FAILURE OF THE PILOT TO OBTAIN THE CLIMB AIRSPEED AND THE INADVERTENT STALL/MUSH.

## Sequence of events

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

- In flight collision with terrain/water, takeoff - roll/run
  - terrain condition - high vegetation
  - directional control - not maintained, pilot in command (cause)
- Loss of control - in flight, takeoff - initial climb
  - airspeed - not obtained, pilot in command (contributing factor)
  - stall/mush - inadvertent, pilot in command (contributing factor)
- Nose over, landing - flare/touchdown

## Analysis

DURING THE TAKEOFF ROLL FROM A PRIVATELY OWNED DIRT AIRSTRIP THE PILOT FAILED TO MAINTAIN DIRECTIONAL CONTROL AND THE AIRPLANE COLLIDED WITH SOME ICE PLANTS.  AFTER THE COLLISION THE PILOT INITIATED AN IMMEDIATE CLIMB TO ARREST THE BEGINNING GROUND LOOP.  THE AIRPLANE BECAME AIRBORNE, BUT STALLED.  THE AIRPLANE NOSED OVER AFTER IT SETTLED INTO THE ICE PLANTS.
