A S7 Sibir Airlines Airbus A321-200N, registration VQ-BGU performing flight S7-5220 from Magadan to Novosibirsk (Russia) with 192 passengers and 7 crew, was climbing out of Magadan's runway 10 when the crew declared Mayday due to unreliable airspeed and related problems with autopilot and autothrust. The aircraft attempted to return to Magadan but had to abort the approach at about 5000 feet, attempted a second time to return to Magadan and again needed to go around due to severe icing. The crew subsequently decided to divert to Irkutsk (Russia) where the aircraft landed safely about 4.5 hours after departure.
