Probable cause & findings
THE PHYSIOLOGICAL INCAPACITATION OF THE CAPTAIN AND HIS LOSS OF CONSCIOUSNESS DUE TO A SYNCOPAL PLEURAL EVENT.
Factual narrative
WHILE CLIMBING THROUGH 11,000 FT MSL THE CAPTAIN LOST CONSCIOUSNESS AND THE FIRST OFFICER TOOK CONTROL OF THE AIRPLANE AND EXECUTED A PRECAUTIONARY LANDING TO AN AIRPORT SHORT OF THE DESTINATION. DURING THE DESCENT THE FIRST OFFICER ADMINISTERED OXYGEN TO THE CAPTAIN AND HE RECOVERED. MEDICAL EXAMINATIONS AND TESTS REVEALED THAT THE CAPTAIN DID NOT HAVE SYSTEMIC MEDICAL PROBLEMS AND THE FLIGHT SURGEON STATED THE LOSS OF CONSCIOUSNESS WAS MOST LIKELY DUE TO A SYNCOPAL PLEURAL EVENT.
