Aircraft Accident/Incident Report
Oklahoma City, Oklahoma 73099
Sunday, February 18, 2007 16:20 CST
NTSB Narrative Summary Released at Completion of Accident
The amateur built gyroplane was flying on the downwind leg for runway 17L, approximately 250 feet downwind from a group of deciduous trees and a row of aircraft hangars, while at an estimated altitude of 100-150 feet above ground level (agl). Near the midfield point, the gyroplane suddenly pitched to a nose down angle of approximately 60 degrees and subsequently impacted the ground. About 30 minutes earlier, a weather observation facility located 12 nautical miles southeast from the site of the accident was reporting, wind from 190 degrees at 21 knots gusting to 24 knots. Inspection of the wreckage did not reveal any mechanical failure/malfunction which would have resulted in the loss of control; however, the investigation did reveal that this was the pilot's first flight after removing the gyroplane's horizontal stabilizer.
NTSB Probable Cause Narrative
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.
