Aircraft involved
Probable cause & findings
The student pilot’s improper approach and landing flare, which resulted in a porpoised landing.
Factual narrative
The student pilot reported that during the approach to land, the airplane was high, and as she descended the airspeed increased. She added that, during the touchdown, the airplane bounced three times and the nose landing gear collapsed. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
