Narrative:
The certificated commercial pilot reported that while in cruise flight over tree-covered terrain, he noted a rough running engine and a slight reduction in engine rpm. Engine emergency procedures did not remedy the engine roughness, which was followed by a rapid loss of engine power, and subsequent loss of altitude. The pilot selected a snow and tree-covered area as a forced landing site. During touch down on the soft, snow-covered terrain, the right main landing gear collapsed, the airplane pivoted to the left, and the left wing struck a stand of trees. The airplane sustained structural damage to the left wing and fuselage. A postaccident inspection of the airplane did not reveal a reason for the loss of engine power.



Probable Cause: A loss of engine power due to an undetermined reason that resulted in a forced landing, a collapse of the main landing gear, and a collision with trees. A factor associated with the accident was the lack of suitable terrain for a forced landing.
