The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

According to the pilot of an amateur-built RV-6A, he experienced a "slight" crosswind from the right while on final approach to the 3,695-foot-long, 50-foot-wide asphalt runway. During the landing flare, the airplane unexpectedly "dropped" and impacted the runway. The airplane then bounced several times, and the nose landing gear collapsed during the last bounce. The airplane continued off the end of the runway and flipped over, resulting in substantial damage to both wings and the fuselage. The pilot reported no mechanical anomalies with the airplane. The winds reported at the closest airport (13 miles to the southeast) at the time of the accident were variable at 3 knots.
