NTSB narrative
ACFT WAS ON PROMOTIONAL FLIGHT FOR MEDIA PERSONNEL THE DAY BEFORE 'SPECTACULAR AIR SHOW' WAS SCHEDULED TO OPEN. PAX WAS LOCAL RADIO STATION MANAGER AND NEWLY RATED PRIVATE PLT, WHO TOLD GROUND CREW HE HOPED THE PILOT WOULD DEMONSTRATE AEROBATICS. WITNESSES SAW ACFT PERFORMING AEROBATICS 7 MINUTES AFTER TAKEOFF. ACFT IMPACTED DESERT TERRAIN AND EXPLODED. BOTH TIP TANKS, OUTBOARD WING PANELS, AND AILERONS WERE FOUND APPROXIMATELY 1-1/4 MILE FROM MAIN IMPACT AREA. METALLURGICAL EXAMINATION DISCLOSED CATASTROPHIC WING SPAR FAILURE DUE TO NEGATIVE BENDING OVERLOAD. THERE WAS EVIDENCE OF AT LEAST ONE OVER-TRAVEL UP AND ONE OVER-TRAVEL DOWN OF BOTH AILERONS. NO PRE-EXISTING OR FATIGUE CRACKS, OR EVIDENCE OF AILERON FLUTTER WAS FOUND.
Probable cause
THE PILOT-IN-COMMAND'S PERFORMANCE OF AEROBATIC MANEUVERS THAT EXCEEDED THE DESIGN STRESS LIMITS OF THE AIRCRAFT, RESULTING IN CATASTROPHIC FAILURE OF THE WING.

- 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.
