NTSB narrative
The pilot and his passenger were taking off on a 2,130-foot turf runway. During the takeoff, the airplane lifted off, remained in ground effect, veered to the left, and then settled back onto the runway where it subsequently impacted a sign and a tree. Postaccident examination of the engine revealed that two of the No. 4 cylinder's three piston compression rings had fractured but remained intact. Since two rings were intact and the third ring was not fractured, compression in the cylinder should not have been substantially reduced. Postaccident computations of ground roll distance showed that the acceleration achieved during the accident takeoff roll was almost equal to that of the airplane's expected performance on hard-surface runways, indicating that there was not a substantial decrease in available propulsive thrust at the time of takeoff. Federal Aviation Administration guidance recommends that pilots ensure that runway length is equal to the aircraft manufacturer's published takeoff or landing distance plus an 80 percent safety margin for takeoffs on a hard surface and double the manual distance for takeoffs on sod.
Probable cause
The pilot's failure to attain an adequate climb rate during the initial takeoff, resulting in the airplane settling back down and departing the runway. Contributing to the accident was the pilot's inadequate preflight planning and preparation.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
