Aeroflot Flight A-13 (Russian: Рейс A-13 Аэрофлота Reys A-13 Aeroflota) was a scheduled Soviet domestic passenger flight from Baku, Azerbaijan to Fort-Shevchenko in Kazakhstan that crashed on 18 August 1973 shortly after takeoff killing 56 of the 64 passengers and crew aboard.

The Antonov An-24 had suffered an engine failure on takeoff and was attempting to return to the airport when it struck an oil rig cable at low altitude resulting in a crash.

At 18:36 MSK on 18 August 1973, CCCP-46435 took off from Baku-Bina International Airport for an approximately 300 miles (480 km) flight to the Kazakh town of Fort-Shevchenko.

On board were sixty passengers, including eleven children, and four crew who were on their second flight of the day.

As it turned, the left wingtip struck the cable of an oil rig in the Caspian Sea, shearing it off.
