Azerbaijan Airlines Flight 56 crashed shortly after takeoff from Nakhchivan Airport, killing 52 people on board.

Azerbaijan Airlines Flight A-56 was a scheduled domestic passenger flight operated by Azerbaijan Airlines, from Nakhchivan Airport to Baku, which crashed whilst attempting an emergency landing on 5 December 1995, killing 52 out of the 82 people on board. The twin-engine aircraft operating the flight, a Tupolev Tu-134B-3, experienced an engine failure shortly after take-off, but the second engine that was operable was shut down in error. The pilots attempted a forced landing, which resulted in the aircraft crashing in the south-western outskirts of Nakhchivan, 3.85 km (2.4 mi) from the airport runway.

Nakhchivan International Airport is a civilian airport and Azeri military airbase located in Nakhchivan, the capital of the Nakhchivan Autonomous Republic, a landlocked exclave of Azerbaijan. The airport was built in the 1970s.
