Probable cause

Loss of directional control during an aborted takeoff. The ditch was a related factor.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of control - on ground/waterTakeoff - aborted
Directional control - not maintainedPilot in commandCause
Ground loop/swerve - uncontrolledPilot in command
On ground/water encounter with terrain/waterTakeoff - aborted

Nose overTakeoff - aborted

Analysis

The pilot performed a preflight and a thorough inspection of the aircraft prior to takeoff. During takeoff, the aircraft accelerated normally, but the pilot stated that it felt sluggish after lift off, so he immediately cut the power and aborted the takeoff. After touchdown, the aircraft veered off the left side of the runway, struck a drainage ditch and nosed over.
