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 while attempting to assess the suitability of a gravel-covered ridge top for future landings in his tail-wheel equipped airplane, he attempted a full flap landing on the main wheels. After bouncing twice, he aborted the landing and adjusted the flaps to 40 degrees and applied full power. During the subsequent takeoff, he felt something hit the airplane, but elected to continue the takeoff and proceed to his final destination. During a postflight inspection, the pilot discovered substantial damage to the lower cross member structure of the fuselage. The pilot stated there were no pre-accident mechanical malfunctions or anomalies that would have precluded normal operation.
