NTSB narrative
THE PVT RATED PILOT DID NOT HOLD A MULTIENGINE OR INSTRUMENT RATING. THE PILOT AND PASSENGER WERE RETURNING FROM VACATION. A WITNESS NEAR THE ACCIDENT SITE STATED THAT SHE SAW THE AIRCRAFT DESCEND OUT OF A LOW OVER LAST AT A VERY STEEP NOSE DOWN ANGLE. THE AIRCRAFT BEGAN TO CLIMB BUT THEN PITCHED DOWN AND SPUN TO THE GND. EXAMINATION OF THE AIRCRAFT WRECKAGE REVEALED THAT LEFT AND RIGHT HORIZONTAL STABILIZER, THE ELEVATORS AND THE RUDDER HAD SEPERATED IN-FLIGHT. EXAMINATION OF THE FAILED COMPONENTS REVEALED EVIDENCE THAT WAS INDICATIVE OF OVERSTRESS DUE TO AERODYNAMIC OVERLOAD.

- 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.
