NTSB narrative
During an aborted takeoff, the airplane impacted a dirt pile and received substantial damage. The pilot said on the previous landing the runway was rough, so he elected to use a soft field takeoff technique. He said that the airplane did not seem to accelerate and he decided to abort the takeoff when the airplane reached 60 MPH. He said that the airplane drifted to the right side of the runway and during the rollout, he was unable to maneuver to avoid impacting a mound of dirt. Subsequent to the accident an examination of the runway found a dirt mound approximately 10 feet in diameter and 3 feet high which extended into the runway about 5 feet. After it was brought to the attention of airport management, the dirt mound was removed.
Probable cause
The pilot's not maintaining proper runway alignment during the aborted takeoff, and the airport personnel not maintaining the runway. Factors were rough terrain and a dirt bank.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1999-06-08.
