Thruster T600N 450, G-CBWJ

Summary:

At approximately 300 ft agl, just after takeoff, the propeller blades, hub and mounting flange detached from the engine, forcing the pilot to land in a nearby field. Forensic examination of the failed flange mounting screws identified high cycle fatigue, possibly due to relative movement between the flange and crankshaft following loss of clamping load.
