Thruster T600N 450, G-KYLE
After about 1¼ hours of flight and whilst the aircraft was climbing, the propeller suddenly detached. The aircraft was damaged as it overran the field selected for the forced landing. The propeller flange mounting screws had failed in fatigue in a manner apparently similar to three previous events investigated by the AAIB and had achieved only about half their operating life of 500 hours.
