An S7 Sibir Airlines Boeing 737-800, legal registration VQ-BKV (illegal disowned registration RA-73665) performing flight S7-2502 from Novosibirsk to Moscow Domodedovo (Russia) with 176 people on board, was in the initial climb out of Novosibirsk's runway 25 when shortly after becoming airborne the right hand engine (CFM56) emitted a series of bangs and streaks of flames, soon after the left hand engine also emitted a series of bangs and streaks of flames. While maintaining about 600 feet AGL the crew managed to stabilize the engines, subsequently climbed to 2000 feet MSL and returned to Novosibirsk for a safe landing on runway 07 about 10 minutes after departure.

Passengers reported they already saw the right hand engine emitting sparks during the takeoff run, shortly afterwards the engine emitted bangs and streaks of flames, a short while later the left hand engine "joined in". The captain announced both engines had failed.

The airline reported both engines were suffering fluctuations in engine speed, the crew was able to restore normal engine operation. The commander decided to return as a precaution for further aircraft inspections and commenced a normal landing. There had been no engine fire.
