Introduction
On 14 October 2009, an Airbus A321-231, registration G-MEDF, operated by a commercial air transport passenger flight from Freetown, Sierra Leone, to London Heathrow Airport, experienced a serious incident involving the commander's incapacitation. The aircraft was manufactured in 2002 and powered by two International Aero Engine V2533-A5 turbofan engines. Seven crew members and 73 passengers were on board; no injuries or damage were reported.
Sequence of Events
The flight was proceeding normally when the commander fell ill. After an initial bout of sickness, he felt considerably improved. Following consultation with the crew, he decided to continue the flight, with the co-pilot assuming the role of pilot flying (PF). Later in the flight, the commander's sickness returned. This required him to be absent from the flight deck at more frequent intervals and for greater periods of time.
To assist the co-pilot, one of the operator's cabin crew members, who was positioning on the flight, was brought onto the flight deck to occupy the jump seat. The commander's condition eventually deteriorated to the extent that he was no longer able to play a role in the operation of the aircraft. He formally relinquished command to the co-pilot.
Aftermath
Following the transfer of command, a diversion was planned and initiated to Malaga, Spain. Medical assistance was requested for the commander's arrival. The approach and landing were uneventful. On arrival, the aircraft was met by an ambulance. The commander was taken to hospital and subsequently made a full recovery. Medical tests were unable to determine the precise cause of his illness.
