Aircraft Accident/Incident Report

Balko, Oklahoma 73931
Saturday, May 30, 1998 19:20 CDT

NTSB Narrative Summary Released at Completion of Accident

During the initial takeoff climb from a pasture, the airplane's main landing gear struck and severed the top wire on a barbed wire fence. The wire 'flipped up' and bent the inboard section of the right aileron down. The pilot was then unable to prevent the airplane from turning left and made a decision to land immediately. He 'forced' the airplane down, impacting on the left wing tip and left main gear. The pilot reported that he had examined the takeoff area before the flight and determined a point at which he would abort the takeoff if not airborne. The airplane lifted off at the pre-determined point, but would not climb out of ground effect. According to the pilot, the wind was gusty, and it was possible the airplane lifted off at the peak of a gust. The pilot also stated that it was hot (93 degrees F) and the density altitude (5,700 feet) was a factor which he had considered in his takeoff planning. He indicated that 'a later departure for cooler temp[erature] or leaving a passenger behind' could have prevented the accident.

NTSB Probable Cause Narrative

The pilot's inadequate preflight planning which failed to assure adequate climb performance to clear an obstacle (fence) during takeoff climb.
