Scheibe SF25B motorglider, G-BLZA

Summary:

Whilst at 1,000 ft on the downwind leg of the circuit of Runway 02, the pilot experienced rapidly increasing airframe vibration; approximately five seconds later the engine stopped suddenly. The pilot noticed that the propeller was no longer attached to the engine and landed successfully on an alternate runway. Investigation revealed that the loss of the propeller was due to the fatigue failure of the bolts securing the propeller back-plate to the crankshaft.
