Aircraft Accident/Incident Report
Delavan, Wisconsin 53115
Saturday, July 25, 1998 14:35 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot added full power and began his takeoff roll. Within 150 feet of where the airplane began its roll, the airplane 'veered sharply to the left, although full right rudder was applied.' The pilot said that he had no steering control. A witness observed the airplane roll forward normally for about two to three seconds, then the nose started rotating upward. Immediately, the airplane veered sharply left and continued off of the runway and on to the grass. The airplane's engine was at full power until the ground impact occurred. Prior to the accident, when the airplane was being taxied to the runway, another witness flagged down the pilot and informed him that the airplane's left tire 'appeared to be low on air.' The witness offered to assist the pilot with inflating the tire, but the pilot elected to taxi to the runway instead. Examination of the airplane revealed the left main landing gear tire pressure at 22 psi. The right main landing gear tire pressure was 26 psi. The Beech F33A Pilot Operating Handbook states that normal tire pressure for the main landing gear tires should be in a range of 33 to 40 psi.
NTSB Probable Cause Narrative
the pilot's failure to maintain aircraft control during the takeoff roll. Factors contributing to this accident were the pilot's inadequate preflight, his operation of an airplane with a known deficiency, low air pressure on both main tires, the snow fence, and the corn.
