Kolb Firefly, G-CEPN
While flying in the local area the pilot heard a loud bang from the rear of the aircraft followed by a loss of thrust. After completing an uneventful forced landing, the pilot discovered that the propeller shaft had failed and the propeller had departed from the aircraft. No other damage to the aircraft was reported. The cause of the failure could not be determined due to the loss of the propeller shaft.
