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 receiving tail wheel instruction (student pilot) stated that during takeoff, he raised the tail wheel too high, and the propeller contacted the ground. The airplane nosed over and came to rest inverted. The student pilot added that there were no preimpact mechanical malfunctions and the flight instructor confirmed the student pilot’s statement. Examination of the wreckage by a Federal Aviation Administration inspection revealed substantial damage to the wings and vertical stabilizer.
