NTSB narrative
THE PILOT WAS PERFORMING AEROBATIC MANEUVERS TO PROVIDE AN OPINION OF THE AIRPLANE TO THE OWNER. FAA RECORDS INDICATE THAT THE PILOT WAS CERTIFIED FOR AEROBATIC MANEUVERS TO THE SURFACE. THE PILOT HAD OVER 300 HOURS OF FLIGHT EXPERIENCE IN THE PITTS. AFTER SEVERAL AEROBATIC MANEUVERS, THE PILOT WAS UNABLE TO COUNTER A NOSE-UP ATTITUDE AND THE AIRPLANE STALLED AND ENTERED A SPIN. HE WAS ABLE TO STOP THE SPIN ROTATION, BUT WAS UNABLE TO CONTROL THE AIRPLANE PITCH PRIOR TO IMPACTING THE GROUND. A C-CLAMP WAS FOUND IN THE AFT FUSELAGE, NEAR THE ELEVATOR CONTROLS. THE CLAMP WAS BENT, GOUGED, AND HAD MARKS WHERE THE PAINT HAD BEEN REMOVED. AN ELEVATOR CONTROL ROD WAS FRACTURED.
Probable cause
A LOSS OF CONTROL DUE TO A FOREIGN OBJECT JAMMING THE ELEVATOR FLIGHT CONTROLS.

Source notes (4)
- 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.
- API snapshot SHA-256: 9be63b1497d255e0e00ee2746a302a6381382f950e6d92853ae4e5baa3c6d08b; retrieved 2026-09-21T14:41:12.021Z.
