NTSB narrative
The pilot reported that his wife had told him she wanted a divorce the day before the accident, and stated: "I believe now I was not prepared to taxi the aircraft, lack of concentration due to stress [sic]." The pilot stated that he applied power, the tail went up, and the aircraft started drifting left. He stated that he then tried to apply right rudder, but "I had left a small cockpit electric heater on [the] floor by [the] rudder pedals, which moved forward [and] locked up [the] rudder pedals." He reported that he was unable to correct the drift and that he then "chopped power" and applied brakes. However, the aircraft went off the left side of the runway, collapsing the right main landing gear and damaging a wing. The pilot indicated on his NTSB accident report that no mechanical malfunction or failure was involved in the accident.
Probable cause
Inadequate preflight inspection/preparation of the aircraft by the pilot and consequent foreign object fouling of the rudder control, rendering directional control impossible. A factor was the pilot's distraction/preoccupation with personal problems.

- 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.
