NTSB narrative
While enroute at cruise altitude during a personal cross-country flight, the pilot lost consciousness. The passenger contacted air traffic control, who provided assistance with navigation and airplane operation, and successfully landed the airplane at a nearby airport.
According to the pilot’s autopsy report, his cause of death was hypertensive and atherosclerotic cardiovascular disease, and his manner of death was natural. The autopsy identified an enlarged heart. All four chambers of the heart were described as severely dilated. Moderate coronary artery disease was present. There was old scar tissue of the left cardiac ventricle, consistent with a past heart attack. The only identified traumatic injuries were sternum and rib fractures following emergency life-saving cardiopulmonary resuscitation (CPR) efforts. Based upon circumstances of the event and the pilot’s significant heart disease identified during the autopsy, it is likely that the pilot suffered an in-flight cardiac event, which resulted in his incapacitation and subsequent cardiac arrest.
Probable cause
The pilot’s incapacitation by an in-flight cardiac event that led to cardiac arrest.

- 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, coordinates, cause areas, damage. 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.
