It turned out that during maintenance, Portuguese experts incorrectly installed the cable aileron control system. Also, Portuguese experts have noted the professionalism of Kazakh crew.

"The crew, realizing that they lacked an effective control of the aircraft, were able to minimize oscillatory movements. An emergency was declared immediately, first was the attempt to diagnose an abnormal cause of the  aircraft's roll, and secondly was the attempt to compete for control. At the same time, the crew had no signs of malfunction from the aircraft systems, there were only constant alerts about abnormal flights.

The situation had not improved, and the trajectories performed made the aircraft and passengers to withstand intense overloads. In some cases, the aircraft was losing control for several moments.

Considering the criticality of the situation, the team several times had requested commands in order to reach the sea, "the CAC stated. The crew understood that ailerons were operated erratically, and any command for the aircraft's roll was minimized.

The aircraft commander had successfully landed the aircraft at Beja Airport. The Aviation Administration expresses its gratitude to Air Astana's crew for the professionalism, appropriate training that made it possible.
