NTSB narrative
The pilot of the Beech B35 attempted takeoff from a west-oriented 2,000-foot dirt/gravel airstrip with four passengers (estimated total occupant weight 755 pounds) with a 2/3 to 3/4 fuel load (as much as 176 pounds). The occupant and fuel weight along with the aircraft's empty weight placed the aircraft close to it's maximum gross takeoff weight, and the weight of the occupants personal effects/baggage was not known. The pilot reported that during the takeoff and while in ground effect the wind reversed to a tailwind and he set the plane down and began applying brakes. The aircraft left the runway, passed through a wire fence, and then rolled into a slight embankment up to a paved road during which the landing gear collapsed. Local law enforcement personnel reported that the pilot stated that the aircraft was too heavy on takeoff. The pilot reported the temperature at the 2,577 foot high airstrip was approximately 90 degrees F., and the density altitude was estimated at 5,000 feet. Surface winds at a reporting station 31 nautical miles west-southwest reported winds out of the northwest ranging from 10 to 16 knots during the period one hour before through one hour after the accident.
Probable cause
The pilot's delay in initiating an aborted takeoff and his failure to establish climb out of ground effect. Contributing factors were the high aircraft weight and high density altitude as well as the fence and berm, which the aircraft struck.

- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2002-08-11.
