NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot reported that the winds were from 260 degrees at 10 knots. During the takeoff roll on runway 28, at about 60 miles per hour, he 'began to bring the tail up for a wheel takeoff.... The airplane began to veer to the left.' He 'attempted to get the airplane straight with right rudder and right brake. The airplane ran off of the runway and ground looped on top of a hill.' The airplane sustained substantial damage to the aft fuselage and empennage. Examination of skid marks on the runway revealed that the right side skid mark was 'more pronounced' than the left side skid mark. No evidence of flight control or brake malfunction was discovered.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

failure of the pilot to maintain directional control during the takeoff roll, which resulted in an inadvertent ground swerve. The crosswind (quartering headwind) was a related factor.
