Incident

During the final approach of a routine flight, the copilot suddenly became incapacitated while reviewing the final approach checklist. The captain, who was flying the aircraft, continued the approach and executed an uneventful landing. After the aircraft arrived at the gate and all passengers had deplaned, the copilot experienced a seizure while being assisted down the aircraft steps by the captain and a flight attendant.

Medical Findings

The copilot was transported to a hospital, where medical tests identified a calcium deposit located behind the right ear. This deposit was applying pressure to the brain. The copilot's last Class I medical examination had been conducted two months prior to the incident.

Outcome

A chemotherapy program was administered, which eventually resolved the medical condition. The copilot's recovery allowed for a return to normal health, as the calcium deposit no longer posed a threat.
