The NTSB's narrative final · quoted from the NTSB record
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.
