Aeroflot Flight 4225 crashes near Almaty International Airport in the then Kazakh Soviet Socialist Republic (present day Kazakhstan) killing all 166 people on board.

Aeroflot Flight 4225 was a Tupolev Tu-154B-2 on a scheduled domestic passenger flight from Alma-Ata Airport to Simferopol Airport on 8 July 1980. The aircraft had reached an altitude of no more than 500 feet when the airspeed suddenly dropped because of thermal currents it encountered during the climb out. This caused the airplane to stall less than 5 kilometres from the airport, crash and catch fire, killing all 156 passengers and 10 crew on board. To date, it remains the deadliest aviation accident in Kazakhstan. At the time, the crash was the deadliest involving a Tupolev Tu-154 until Aeroflot Flight 3352 crashed in 1984, killing 178 people.

Almaty International Airport is an international airport in Almaty, Kazakhstan. It is larger than Nursultan Nazarbayev International Airport (NQZ) in Astana and is the main international gateway into the country. It is a principal hub of Air Astana, the national flag carrier, as well as other domestic and international airlines. The airport plays role in connecting Almaty to the rest of the country and the broader region through its extensive transport links.

The Kazakh Soviet Socialist Republic, also known as Soviet Kazakhstan, the Kazakh SSR, KSSR, or simply Kazakhstan, was one of the constituent republics of the Soviet Union (USSR) from 1936 to 1991. Being located in northern Central Asia, the Kazakh SSR was created on 5 December 1936 from the erstwhile Kazakh ASSR, which was an autonomous republic of the Russian SFSR. It shared borders with its fellow Soviet republics of Russia, Kyrgyzstan, Turkmenistan and Uzbekistan, while also sharing an international border with the People's Republic of China.

Kazakhstan, officially the Republic of Kazakhstan, is a landlocked country primarily in Central Asia, with a small portion in Eastern Europe. It borders Russia to the north and west, China to the east, Kyrgyzstan to the southeast, Uzbekistan to the south, and Turkmenistan to the southwest, with a coastline along the Caspian Sea. Its capital is Astana, while the largest city and leading cultural and commercial hub is Almaty.
