Analysis

While being vectored to intercept the localizer course at an altitude of aprx 2200 ft, aprx 5 miles from the arpt, the RPM gauge fluctuated. The plt applied full throttle, mixture & propeller controls, but the eng then lost power. During a subsequent off-airport forced landing at night, the acft collided with trees. An exam of the eng revealed evidence of oil starvation. The eng driven oil pump drive shaft had failed from overload after foreign object(s) became lodged between the housing & the gears. Also, there was evidence of eng seizure after the #6 connecting rod had failed & that the #5 connecting rod had failed from overload.
