Pulkovo Aviation Enterprise Flight 612 was a scheduled passenger flight operated by Saint Petersburg-based airline Pulkovo Aviation Enterprise, flying from Anapa Airport to Pulkovo Airport in Saint Petersburg. The aircraft crashed in Donetsk Oblast in eastern Ukraine, near the Russian border, on 22 August 2006. All 170 people on board were killed.

The crash was the deadliest aviation accident in 2006. At the time it was the deadliest crash in modern Ukrainian history and the second deadliest in Ukraine SSR, after the 1979 Dniprodzerzhynsk mid-air collision. The death toll was eventually surpassed in 2014 when Malaysia Airlines Flight 17 was shot down 40 miles (64 km) east of where Flight 612 had crashed, also located in Donetsk Oblast, killing all 298 people on board.

Pulkovo Aviation Enterprise Flight 612 was served by a Russian Tupolev Tu-154M airliner (registration: RA-85185). The aircraft did not refuel in Anapa and departed on time. "The Pulkovo Airlines flight departed Anapa as scheduled. All necessary maintenance was performed as required before departure," said Oleg Tolstyh, General Director of Anapa's Vityazevo Airport. The aircraft was manufactured in 1992 and had been in service for approximately 25,000 flight hours. It had first flown in China until Pulkovo Aviation Enterprise acquired it in 2001.

The captain of the aircraft, 49-year-old Ivan Ivanovich Korogodin (referred to as "Vanya" on the CVR recording), had 12,312 hours of flying experience, 5,956 of which were as a pilot of a Tu-154.[4] The first officer, 59-year-old Vladimir Vladimirovich Onishchenko, had 11,876 flight hours, including 2,200 hours on the Tu-154. 23-year-old Andrei Nikolaevich Khodnevich, a trainee pilot, was also on board the aircraft and had only 189 flight hours, with 88 of them on the Tu-154.
