Probable cause
A complete loss of power due to failure of the impeller drive gear train and displacement of the blower spring drive mechanism, which resulted in seizure of the propeller shaft/crankshaft. Also causal was the failure of the phenolic separator bracket of the rear impeller support bearing for undetermined reasons. A factor was the none suitable terrain for the forced landing.
