NTSB narrative
Witnesses observed the airplane fly at a low altitude over the water and, during a steep left turn, nose over and impact the water about 50 yards offshore. First responders rescued the pilots, a certified flight instructor (CFI) and a pilot who was receiving instruction, who told them that the airplane and engine had no mechanical failures or malfunctions during the flight. The CFI succumbed to his injuries 17 days later. Examination of the airframe and engine revealed no mechanical abnormalities that would have precluded normal operation. The airplane was equipped with a shoulder harness restraint that connected to the crotch strap; however, there was no lap belt installed. Examination of the restraint system webbing revealed no visual signs of distress or damage. During the impact sequence, the rear bulkhead separated from the fuselage allowing the rear seat and CFI to be pushed into the front seat. The investigation determined that the airplane had been designed without a lap belt restraint. The inadequacy of the restraint system likely exacerbated the CFI's injuries. The requirements under the American Society for Testing and Materials international standards stated that there must be a seat belt and harness for each occupant and adequate means to restrain the baggage.
Probable cause
The pilot's failure to maintain aircraft control during a low-altitude maneuver. Contributing to the accident was the pilot's decision to perform a maneuver at a low altitude that was insufficient to allow him to recover from the loss of control. Contributing to the occupants’ injuries was the inadequacy of the restraint system design by the manufacturer.

- 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 2008-10-08.
