Immediately after becoming airborne the no. 1 propeller went into the feathered position. The crew were not able to restart the engine and unfeather the prop. A belly landing was carried out in a small clearing. Weather at the time of the accident included low ceiling, rain showers, turbulent air and gusts to 40 mph.
PROBABLE CAUSE: "1) A mechanical failure of the torquemeter boost pump that automatically feathered the left propeller immediately after becoming airborne, and 2) the use of an uncorrect procedure for unfeathering which resulted from the ambiguity of the instruction for unfeathering contained in the company's manual."
