NTSB summary
HISTORY OF FLIGHT On February 18, 2007, about 1620 central standard time, a Stevens KB-2 single-engine gyroplane, N6KT, was substantially damaged when it collided with terrain while on the downwind leg of the traffic pattern at the Clarence E Page Municipal Airport (F29), near Oklahoma City, Oklahoma. The commercial pilot, the sole occupant, sustained fatal injuries. The gyroplane was registered to and operated by the pilot. Visual meteorological conditions prevailed and no flight plan was filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight originated approximately 1555. According to witnesses at the airport, the pilot initially departed runway 17L and completed one circuit around the traffic pattern. While approaching the north end of runway 17L the pilot appeared to "hover" into the wind and performed several "rudder turns." The pilot then proceeded to perform a touch-and-go maneuver and started around the traffic pattern a second time. The witnesses further reported that while on the downwind leg of the traffic pattern, the gyroplane appeared to fly straight and level at an estimated altitude of 100-150 feet above ground level (agl). About half way along the downwind leg of the traffic patern, the gyroplane suddenly pitched to a nose down attitude and subsequently impacted the ground. One witness reported that the gyroplane descended with an approximate nose down angle of 60 degrees "while rolling left and right." PERSONNEL INFORMATION The pilot, age 46, held an airline transport pilot certificate with ratings for airplane single-engine
Probable cause
The pilot's failure to maintain control of the gyroplane while in the traffic pattern. Contributing to the accident was the high wind with terrain induced turbulence and the absence of the gyroplane's horizontal stabilizer.
