Seattle - Missoula

While performing an ILS approach at night and in IMC, the airplane collided with trees in mountainous terrain prior to the IAF. The MDA prior to the IAF is 10,600 feet. The descent altitude at the outer marker is 7,713 feet. The wreckage was located under the localizer path at an elevation of 7,600 feet. Damage to tree tops along the wreckage distribution path indicates that the airplane travelled through the trees on a level plane until contact with the ground approximately 300 feet into the path. Light snow was falling at the time of the accident and visibility was deteriorating due to fog. During the post crash investigation, there was no evidence found to indicate a mechanical failure or malfunction.
