## Probable cause

THE PILOT'S LOSS OF CONTROL OF THE AIRCRAFT DUE TO A LOSS OF CONSCIOUSNESS BROUGHT ON BY REACTIVE HYPOGLYCEMIA.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, approach - vfr pattern - final approach
  - aircraft control - uncontrolled, pilot in command (cause)
  - incapacitation(hypoglycemia/diet), pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

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.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
