The cause of the accident was due to the fact that after takeoff, as the aircraft gained altitude, a failure when configuring the pressurization regulator caused the loss of consciousness of both the pilots and the passengers due to hypoxia, turning the aircraft into at that time in a "ghost flight" that was only kept flying by the operation of the autopilot. The passengers comprised 103 Cypriot nationals and 12 Greek nationals. The passenger list included 93 adults and 22 children.

The reason for this fatal air crash was a simple mechanical setting done by the ground engineer before the flight.
