PROBABLE CAUSE: "The aircraft, flying on instruments, drifted north of its normal track because of strong winds and crashed into the mountain.
Contributing factors' 1) The winds were stronger than forecast; 2) An accurate bearing could not be obtained at Mus, and Van had not been checked; 3) Sub-normal temperatures would result in a high indicated altimeter reading; 4) Calculations on the flight and contacts with beacons were not coordinated and controlled."
