NTSB narrative
A FLIGHT INSTRUCTOR-WITNESS OBSERVED THE ACCIDENT PILOT CRUISING HIS EXPERIMENTAL AIRPLANE AT ABOUT 600 FEET ABOVE GROUND LEVEL. ACCORDING TO THE WITNESS, THE AIRPLANE GRADUALLY NOSED OVER AND DESCENDED 'STRAIGHT TOWARD THE GROUND.' THERE WAS NO REPORT OF ANY OTHER AIR TRAFFIC IN THE VICINITY. THE SKY WAS CLEAR AND THE WIND WAS LIGHT AND VARIABLE. NO EVIDENCE WAS FOUND OF ANY PRE-IMPACT MECHANICAL MALFUNCTION, AND THE ENGINE APPEARED CAPABLE OF OPERATION. THE TERRAIN IN THE VICINITY OF THE ACCIDENT SITE CONSISTED OF AN OPEN FIELD. THE REASON THE PILOT FAILED TO MAINTAIN CONTROL OF HIS AIRPLANE WAS NOT ESTABLISHED.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN CONTROL OF HIS AIRPLANE FOR UNDETERMINED REASONS.

- 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 1992-05-09.
