Circumstances:
On a flight from Baku to Aktau in difficult weather conditions at night when took off with caged gyro horizons, so the crew lost spatial orientation. Aircraft entered a steep right downward spiral and crashed on the shore of the Caspian Sea near Nardaran, some 35 km northeast of Baku, less than five minutes after takeoff. All 5 crew and 18 passengers were killed. Among them were 15 Azeris, one Briton, one Australian, one Turkish, one Georgian and 4 Kazakh.
Probable cause:
The gyro horizons failed after takeoff due to a malfunction caused by the fact that some counterfeit assemblies and instruments had been installed by KhGAPP during the production of the aircraft. While cruising by night and poor visibility, the crew lost situational awareness and spatial orientation.
