The CASA cargo plane departed Bethel (BET) at 18:23 on a flight to Toksook Bay (OOK), and Tununak (TNK) before returning to Bethel.
As the flight approached Toksook Bay the crew prepared for an approach and landing on runway 16. The first officer was pilot flying. As the first officer maneuvered the airplane from base leg to final, she advanced the engine power levers to adjust the airplane’s approach path, but there was no response from the right engine. The airplane began to yaw to the right, and the captain took control of the airplane, initiated a go-around, and added full engine power in an attempt to climb the airplane away from rising terrain. About 500 to 600 feet above the ground, the airplane's yaw to the right intensified, and it began to descend rapidly. The captain applied full left aileron and rudder to correct the yaw, but he was unable to maintain altitude. He selected an area of tundra-covered terrain as a forced landing site. The airplane struck the ground with the right main landing gear, and right front portion of the fuselage. The airplane sustained substantial damage to the fuselage, wings, and empennage.

Probable Cause:

PROBABLE CAUSE: "The flight crew’s inability to adjust/increase power to the right engine during the landing approach due to an in-flight disconnect of the engine power control linkage, resulting in a loss of control of the airplane. Contributing to the accident was the flight crew’s delayed response in feathering the right engine propeller."
