What happened
On January 17, 2011, an Air France Boeing 777-228, registration F-GSPM, departed Paris Charles de Gaulle for New York J.F. Kennedy. During the flight over the Atlantic Ocean, the captain began experiencing physical distress. At approximately 10:00 UTC, the captain felt unwell, prompting the crew to request medical assistance from a passenger who was a physician. Following an initial assessment, the captain decided to continue the flight.
By 10:27 UTC, the aircraft entered oceanic airspace. Around 11:30 UTC, the captain experienced intensified abdominal pain. The onboard physician, a cardiologist, performed a second examination and noted that the captain appeared very pale, exhibited body stiffness, and was experiencing tremors. Fearing the possibility of an internal hemorrhage, the physician advised medical intervention. At 11:42 UTC, the crew decided to divert to the nearest suitable airport, Keflavik, Iceland, and the co-pilot transmitted a distress message via HF radio to Gander control.
During the descent, the captain's condition stabilized sufficiently to allow him to continue performing his duties as Pilot Not Flying (PNF). The aircraft landed at Keflavik at 13:13 UTC. Upon arrival at the parking stand, medical services evacuated the captain for hospital treatment.
The investigation
The BEA examined the crew's response to the medical emergency and the airline's operational procedures. The investigation focused on the communication between the cockpit and the airline's Operations Control Center (CCO), as well as the clarity of command transfer protocols during pilot incapacity.
Findings
- The primary cause of the diversion was the sudden onset of abdominal pain in the captain, the exact nature of which could not be determined.
- The crew did not notify the airline's CCO of the initial medical episode, which prevented the company from providing specialized medical advice or coordinating with emergency services (SAMU).
- There was no explicit transfer of command between the captain and the co-pilot. This lack of formal handover created a risk of ambiguous authority, where the co-pilot might hesitate to take full command due to the presence of the incapacitated captain.
- The airline's operational manuals were found to be imprecise regarding the transfer of responsibilities during pilot incapacity. Furthermore, the procedures for handling "sick passengers" were not adequately adapted for medical emergencies involving flight crew members.
