NTSB summary
HISTORY On March 20, 1997, approximately 1735 central standard time, a homebuilt Teschendorf Cassutt Sport airplane, N86T, was destroyed during impact with terrain following an in-flight airframe failure while maneuvering at the Stilwell Airport, near Stilwell, Oklahoma. The commercial pilot, sole occupant in the airplane, was fatally injured. The airplane was owned and operated by the pilot under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the cross-country personal flight which originated from Cookson, Oklahoma, approximately 30 minutes before the accident. No flight plan was filed. According to a witness, "the plane was going north [parallel to the runway], about 50 feet off the ground and at a high rate of speed." Another witness reported "seeing it flying very low and [I] thought it was going to hit the metal building there at the airport but I saw him roll real fast to the right." Another witness estimated that the airplane was traveling faster than 200 mph just before he saw the airplane's right wing skin separate from the airplane and then the right wing came off. The airplane was observed to roll several times and travel approximately 1100 feet before it impacted the ground. PERSONNEL INFORMATION According to the pilot's wife, he had learned to fly helicopters in the Army and fixed winged aircraft in the Air Force. FAA medical records indicate, as of January 13, 1997, that he had a total of 6,527 flight hours with 100 hours in the last 6 months. AIRCRAFT INFORMATION The airplane was a homebuilt experimental aircraft designed for racing and
Probable cause
failure of the right wing spar and/or debonding of the right wing skin, which resulted in separation of the wing skin and a portion of the right wing, during high speed flight. Factors related to the accident were: previous wing damage and inadequate maintenance by other (unknown) personnel.
