Thruster T600N 450, G-EVEY
Summary:
The student had just climbed the aircraft to the circuit height of 700 ft, turned downwind and was throttling the engine back to cruise power, when a rumbling noise was heard from the front of the engine. Approximately ten seconds later the propeller detached from the engine. The instructor took control and completed a successful forced landing in a field which he often used for practice engine failures after takeoff. There were no injuries and the aircraft suffered no further damage. Subsequent examination revealed evidence of extensive fatigue crack propagation in the propeller attachment bolts, which eventually failed in ductile overload, causing the propeller to detach.
