Safety record

Accident & incident history

2016-05-24 Accident · Texarkana, AR Damage: Substantial Minor injury NTSB · CEN16LA197
Reported aircraft: Cessna 501
Probable cause: The pilot's failure to use supplemental oxygen as required during high-altitude flight, which resulted in his loss of consciousness following a loss of cabin pressurization. Contributing to the accident was the separation of the air conditioning system's primary pressurization duct and the subsequent failure of the aft pressure bulkhead check valve flapper due to progressive weakening from age.
