The first three ignitions of the Briz-M proceed normally. But during the fourth ignition, the S5.98M engine stopped working 240s earlier than planned.
Consequently, the orbit reached is not the one planned. The Yamal-402 satellite is nevertheless released and works correctly. It completes four ignitions of one of its engines to reach the desired orbit, and it reaches the geostationary orbit at 55°E on December 28, 2012.

Mission Details
Yamal 402
In February 2009 Gazprom Space Systems ordered two Yamal-400 communications satellites from Thales Alenia Space. The satellites named Yamal 401 and Yamal 402 will be based on the Spacebus-4000C3 bus and are planned to be launched in 2011. According to the signed document Thales Alenia Space, as the prime contractor, will be responsible for the design, manufacture, testing, and turnkey delivery of Yamal-401 and Yamal-402 satellites as well as for the associated ground segment deployment. Originally planned to be launched on Ariane-5ECA vehicles, the satellites have now been transferred to Proton-M Briz-M rockets.
Yamal-400 satellites will have a guaranteed lifetime of 15 years. Yamal-402 will be placed at a 55° East orbital slot and will be equipped with 46 Ku-band transponders providing for the coverage zone over most parts of the territory of Russia, CIS, Europe, the Middle East, and Africa.
