Circumstances:
While cruising at an altitude of 12,000 feet on a flight from Buckley AFB, Denver, and Seattle, the navigator informed ATC about difficulties to maintain the assigned altitude and was cleared to descend to 10,500 feet. Few minutes later, the copilot reported icing conditions to ATC and requested the permission to gain altitude. About 20 minutes later, while cruising at the altitude of 10,000 feet in marginal weather conditions, the four engine airplane struck the slope of Mt Tobin (2,980 meters high). The wreckage was found few hours later about 300 meters below the summit and all 19 occupants have been killed.
Probable cause:
It is believed the accident was not the consequence of icing conditions but a loss of control caused by atmospheric downdrafts.
