The crew started the descent to Kathmandu in poor weather conditions when the airplane crashed on a mountainous area located about 20 km from the airport. Following a navigational error on part of the pilots, the airplane followed a wrong approach path to Kathmandu Airport and went into the wrong valley. At the last moment, the pilot-in-command made a sharp turn to avoid the mountain but the aircraft stalled due to an insufficient speed and crashed on a rocky slope. The aircraft was destroyed upon impact and all 20 occupants have been killed.
