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 a gust of wind blew the airplane to the left of the runway as he was landing. He tried to abort the landing; however, the airplane barely lifted off the ground. The airplane continued to the left off of the runway and landed hard about 100 feet from the runway and ground looped. A Federal Aviation Administration (FAA) airworthiness inspector examined the airplane; he established flight control continuity from the cockpit to the rudder and elevators. The rudder pedals operated smoothly with no restrictions. The main landing gear wheels and tail wheel were also inspected with no mechanical abnormalities noted.
