## Probable cause

THE PILOT'S USE OF IMPROPER STARTING PROCEDURES WHICH RESULTED IN THE LOSS OF CONTROL OF THE AIRPLANE.  A FACTOR IN THE ACCIDENT WAS THE AIRPLANE'S ENCOUNTER WITH ROUGH TERRAIN DURING THE UNMANNED TAXI.

## Sequence of events

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

- Loss of control - on ground/water, standing - starting engine(s)
  - starting procedure - improper, pilot in command (cause)
- On ground/water collision with object, taxi
  - object - fence
- Nose over, taxi
  - terrain condition - rough/uneven (contributing factor)

## Analysis

WHEN THE PILOT ATTEMPTED TO START THE AIRPLANE HE FOUND THAT IT HAD A DEAD BATTERY.  HE THEN INSTRUCTED THE NON-RATED PASSENGER ON HOW TO MANIPULATE THE ENGINE CONTROLS AND PROCEEDED TO HAND PROP THE ENGINE.  THE ENGINE STARTED AT FULL THROTTLE AND THE PILOT WAS UNABLE TO BOARD THE AIRPLANE AS THE PASSENGER WAS BLOCKING THE ENTRY IN HIS ATTEMPT TO GET OUT.  THE AIRPLANE SUBSEQUENTLY ROLLED ACROSS A RUNWAY, THROUGH THE AIRPORT BOUNDARY FENCE, THROUGH A DITCH, AND ACROSS A ROAD INTO AN OPEN FIELD BEFORE THE NOSE GEAR COLLAPSED AND IT NOSED OVER.  NO CHOCKS WERE USED DURING THE START.
