Probable cause

The pilot's loss of directional control. A factor in the accident was his inadequate compensation for wind conditions.

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 made a precautionary landing due to a slightly high oil temperature. After five minutes on the ground he attempted to take off in a cross wind from the dry lake bed when he lost directional control and the right skid contacted soft ground and rolled over.
