## Probable cause

THE PILOT'S POOR JUDGEMENT IN ATTEMPTING THE TAKEOFF FROM THE PARKING RAMP WHEN A 12,000-FT RUNWAY WAS AVAILABLE.

## Sequence of events

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

- Overrun, takeoff - aborted
  - judgment - poor, pilot in command (cause)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)

## Analysis

IN ORDER TO SAVE TIME, THE PILOT ATTEMPTED A TAKEOFF FROM THE 1,200-FT LONG PARKING RAMP INSTEAD OF THE AVAILABLE 12,000-FT LONG RUNWAY. THE AIRPLANE WAS EQUIPPED WITH A CRUISE PROPELLER THAT WILL NOT DEVELOPE FULL RPM DURING TAKEOFF. THE TAKEOFF RUN WAS ABORTED, AND THE AIRPLANE OVERRAN THE RAMP COMING TO REST IN WATER AND MUCK.
