NTSB narrative
THE FLIGHT HAD BEEN CLEARED TO LAND ON RWY 18L, BUT LINED UP FOR RWY 17. THE TOWER INFORMED THE PILOT THAT HE WAS ON FINAL FOR THE WRONG RUNWAY & CLEARED HIM TO LAND ON ON RWY 17. THE PILOT STATED THAT AT ABOUT 200-300 FT HE BECAME DIZZYAND BLACKED OUT. THE AIRPLANE CAME TO REST INVERTED. THE PILOT'S LOSS OF CONSCIOUSNESS WAS LATER DIAGNOSED AS REACTIVE HYPOGLYCEMIA COMPOUNDED BY THE PILOT'S IMPROPER DIETARY HABITS.
Probable cause
THE PILOT'S LOSS OF CONTROL OF THE AIRCRAFT DUE TO A LOSS OF CONSCIOUSNESS BROUGHT ON BY REACTIVE HYPOGLYCEMIA.

- 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.
