Safety record

Accident & incident history

2009-07-25 Accident · Escondido, CA Damage: Substantial Minor injury NTSB · WPR09LA369
Reported aircraft: Brown Michael Kitfox IV
Probable cause: A total loss of power due to an oil exhaustion induced seizure of the engine. The pilot's decision to continue flight to the original destination after becoming aware of the in-flight oil leak instead of landing at an intermediate airport to investigate the source and extent of the problem is also causal. Contributing to the accident was the pilot's reuse of the pushrod oil seal during maintenance in contradiction to the engine manufacturer's maintenance instructions.
1982-08-20 Accident · Orlando, FL Damage: Destroyed Minor injury NTSB · MIA82DA173
Reported aircraft: Air & Space 18A — a different aircraft that carried the N6140S registration before this airframe.
