NTSB narrative
Witnesses saw the airplane touch down hard and porpoise three times during the student pilot's third landing on her first solo flight. The student pilot reported that during the initial touchdown she decreased the engine power too soon for the flare and hesitated too long. Thereafter, she should have increased engine power but said she forgot what to do. The airplane engine's firewall was found bent during a subsequent airframe inspection. The student pilot's total flight time was about 29 hours.
Probable cause
An inadvertent pilot-induced porpoise resulting from the pilot's improper landing flare and inadequate power management.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
