Probable cause

The pilot's failure to maintain directional control of the aircraft during the takeoff ground run due to inadequate compensation for the existing wind conditions. A factor in this accident was the unfavorable wind reported by the pilot.

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.

Analysis

The pilot reported that during the takeoff run on runway 30 the aircraft 'crossed a point of change in elevation.' He said the airplane became 'light' and did not have enough airspeed to be controlled by the rudder or aileron. He said the wind caused the aircraft to drift off the airstrip to the west. The pilot reported the wind direction was from 080 degrees at 7 miles per hour, gusting to 10 miles per hour. The aircraft continued, without the pilot being able to gain control, until it collided with a ditch.
