What happened
During the cruise phase of flight, the pilot in command (PIC) became unconscious while maintaining control of the aircraft. The airplane was occupied by another individual, identified as the co-owner and a rated pilot, who was seated in the right front seat. Upon noticing the PIC's incapacitation, this second pilot assumed control of the aircraft.
The pilot taking control successfully diverted the flight to a nearby airport. Following the landing, the unconscious PIC was transported to a local hospital. Medical personnel at the hospital pronounced the individual deceased. An autopsy was not performed on the body. However, the attending physician determined that the cause of death was a heart attack.
The investigation
The investigation focused on the circumstances surrounding the in-flight incapacitation and the subsequent actions taken by the second pilot. The mechanical condition of the aircraft was reviewed to ensure no technical failure contributed to the event. No mechanical anomalies were identified as contributing factors.
Findings
The primary factor in this accident was the pilot's sudden medical incapacitation. The heart attack resulted in the immediate loss of consciousness, creating a critical emergency situation that required rapid intervention by the second pilot. The successful diversion and landing were attributed to the quick actions of the co-owner who was also a rated pilot.
Safety message
This event highlights the risks associated with sudden medical emergencies during flight. Pilots are encouraged to be aware of their health status and consider having qualified passengers or crew available who can assume control if necessary.
