Circumstances:
On the non stop leg from Boise to Denver, while flying by night and poor visibility, the aircraft hit the slope of Mt Elk located southeast of Elk Mountain, south Wyoming. The wreckage was found few hours later in a deep snow and in poor weather conditions, about 340 feet from the summit. The aircraft was destroyed by impact forces and all 21 occupants were killed. At the time of the accident, the aircraft deviated from the prescribed flight path by 4,5 miles and its altitude was 11,000 feet.
Probable cause:
On the basis of the foregoing the Board finds that the probable cause of this accident was the deviation from the prescribed route at an altitude insufficient to assure adequate clearance over Elk Mountain.
