## Probable cause

the pilot's failure to maintain directional control during the aborted takeoff. A contributing factor was the mud.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - aborted
  - directional control - not maintained, pilot in command (cause)
- Nose over, takeoff - aborted
  - terrain condition - muddy (contributing factor)

## Analysis

According to the pilot, he "did not feel [he] was gaining the speed [he] needed for rotation" and aborted the takeoff roll. The airplane drifted to the right and the right main landing gear "got into the mud on the right side of the runway." The airplane nosed over resulting in substantial damage. An examination of the airplane's systems revealed no anomalies.

## Factual narrative

According to the Pilot/Operator Aircraft Accident/Incident Report form submitted by the pilot, he "did not feel [he] was gaining the speed [he] needed for rotation" and aborted the takeoff. The airplane drifted to the right and the right main landing gear "got into the mud on the right side of the runway" and the airplane nosed over. According to the Federal Aviation Administration inspector who examined the airplane, the right wing was bent up 45 degrees, 3 feet inboard from the tip. The fuselage was wrinkled behind the cabin door and the vertical stabilizer was bent 45 degrees at the fuselage. An examination of the airplane's systems revealed no anomalies.
