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

According to the student pilot, during a solo flight, he stayed in the pattern and performed takeoffs and landings. During the third landing, the airplane was high, and his approach angle was steep. He reported that he reduced the power and trimmed the airplane for landing. During the touchdown, the airplane bounced twice, and the propeller struck the ground. The airplane sustained substantial damage to the cabin floor. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
