## Probable cause

THE PILOT'S FAILURE TO USE PROPER STARTING PROCEDURES AND THE EXCESSIVE THROTTLE SETTING.

## Sequence of events

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

- On ground/water collision with object, taxi
  - throttle/power control - improper, pilot in command (cause)
  - starting procedure - improper, pilot in command (cause)
  - object - fence

## Analysis

WHILE HAND PROPPING HIS UNATTENDED AIRCRAFT, THE PILOT SAID HE FELT HE LEFT THE THROTTLE TOO FAR ADVANCED, AND WHEN IT STARTED, THE ACFT BEGAN TO ACCELERATE. HE ATTEMPTED TO RUN AROUND TO THE CABIN DOOR TO GAIN CONTROL, BUT WAS INJURED WHEN HE WAS STRUCK BY THE HORIZONTAL STABILIZER. THE ACFT CONTINUED ON AND STRUCK A AIRPORT FENCE.
