Sequence of events

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

The pilot stated that during landing the airplane's tail began to "oscillate" when it contacted the runway. The airplane then drifted off the right side of the runway and the right main landing gear wheel encountered the adjacent terrain. The airplane nosed over and sustained substantial damage that included wrinkling of the left wing skin, damage to the vertical stabilizer, and damage to the left side of the fuselage near the windshield. The pilot and pilot-rated passenger were uninjured. No mechanical anomalies that would have precluded normal operation were noted.

The airplane nosed over and sustained substantial damage that included wrinkling of the left wing skin, damage to the vertical stabilizer, and damage to the left side of the fuselage near the windshield. The pilot and pilot rated passenger were uninjured. No mechanical anomalies that would have precluded normal operation were noted.
