Analysis

The plt reported a loud bang was heard and he observed the left eng cowl raised to a vertical position & the eng drooped downward. The excessive amount of drag caused the acft to be uncontrollable. The plt was able to gain control of the acft by feathering the right eng. A gear-up landing was made in a pasture. One blade had separated from the left propeller due to separation of a flange on the propeller hub. The separated hub flange failed due to high cyclic metal fatigue.
