N736AS

Probable cause: The pilot's improper decision to conduct multiple visual approaches to the destination airport despite the night instrument meteorological conditions; the airplane's low fuel state at that time, which resulted in a total loss of engine power due to fuel exhaustion; and the pilot's subsequent failure to maintain adequate airspeed, which led to an aerodynamic stall and a loss of control. Contributing to the accident was the pilot's operation of the flight with a medical certification limitation that precluded him from night flying.
