- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

NTSB narrative
Following takeoff on his first solo flight in the aircraft, the nose of the aircraft continued to rise and the pilot could not lower the nose with full nose down elevator application. In addition, according to the pilot, the aircraft was right wing heavy. The owner of the aircraft could not provide specific performance or weight and balance information, but stated the center of gravity tended to be 'somewhat' forward with lighter weight in the cockpit. The owner was approximately 30 to 40 pounds heavier than the pilot. In addition, following the accident, examination provided evidence that the right lift strut support cable was not connected at the upper fitting and exhibited no evidence of impact damage.
Probable cause
Attempt by the pilot to fly the aircraft with the center of gravity out of limits. A factor was a disconnected lift strut support cable.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1997-06-27.
