Aeroflot Flight 558 (Russian: Рейс 558 Аэрофлота Reys 558 Aeroflota) was a scheduled Ilyushin Il-18V domestic passenger flight from Karaganda to Moscow that crashed into a field in the Abzelilovsky District on 31 August 1972 as a result of a fire stemming from exploded passenger baggage, killing all 102 people on board.

The flight was granted permission to descend to an altitude of 4,800 meters and then switched over to Magnitogorsk air traffic control.

The flight crew informed Magnitogorsk that there was a fire in the second cargo compartment, and requested instructions for an emergency landing.

At 10:15:50 the Il-18 was in dangerous proximity to the ground; the pilots responded by pulling on the controls, putting the engines in takeoff mode, and retracting the landing gear simultaneously, but the sudden overload on the aircraft caused by the maneuvers along with the passengers moving to the front of the plane to avoid the smoke caused an unanticipated reduction in climb.

The final report stated: The cause of the accident was the rapid development of the fire that had developed in the second trunk, which led to a complete or partial loss of the crew's working capacity; causing the impossibility of following visual flight and observation of instruments due to smoke in the pilot's cabin resulting in the impossibility of a successful flight outcome.After the accident the design of the Ilyushin Il-18 was modified to allow people in the cabin to enter the second baggage compartment if necessary.
