NTSB narrative
While practicing her sportsman competition sequence, the pilot deliberately entered a spin to the left. According to a witness, the pilot had been having trouble with her spin entries in the past, and that this entry was the cleanest he'd seen her perform. After 1 1/4 turns, the airplane's rotation slowed, but approximately two turns later, the rotation accelerated, and the airplane transitioned to an inverted spin. The pilot radioed that she could not recover from the spin and was advised to left go of the controls. Fifty feet prior to impact, the descent rate, and rate of rotation of the airplane slowed. Also, the nose of the airplane was recovering from a vertical down position. The day of the accident, the pilot purchased 12 pounds of weight to be installed on her airplane to move the center of gravity aft. According to the FAA's Flight Training Handbook, 'The recovery from a stall in any airplane becomes progressively more difficult as its center of gravity moves aft. This is particularly important in spin recovery....'
Probable cause
The pilot's inability to recover from an intentional stall spin maneuver. A factor in the accident was the change in the airplane's center of gravity which made the airplane more difficult to recover from a spin.

- 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.
