The Flydubai FZ981 crash in Rostov-on-Don, Russia, could have followed the pilots’ failure to manage the landing after taking control of the system, media reveal citing flight data. The final minutes are said to have been full of arguments and screams of terror.
Now that decoding of the flight data recorders of the crashed Boeing is complete, an unnamed source told Russian daily Kommersant that pilot error is now dominating the investigation as the probable cause.
It appears that while trying to gain altitude after an unsuccessful landing attempt in bad weather, one of the pilots pulled the control stick up too much, causing a stall break and an uncontrollable nosedive.
The Interstate Aviation Committee believes that the official results of the decoding will be made public within a week or two.
Meanwhile, according to Kommersant’s sources, the recorder revealed that flight FZ981 had made two attempts to land in automatic mode, and since a veering squall wind hampered the second attempt, the pilot decided to make a third approach for landing in manual mode.
One of the pilots pressed the TOGA (Take off. Go around) button and turned off the autopilot, writes the daily.
Anonymous experts Kommersant talked to believe the pilot did not manage the diving rudder and horizontal stabilizer, which steer the plane in opposite directions – down and up, respectively.
When the pilot pulled up, he put both the rudder and stabilizer in a sharp climb mode, somewhat fighter-jet style, plus enacted the TOGA regime’s retracted flaps, decreasing ascending force. As a result, the aircraft lost speed and got into the beyond-stall angle of approach. All this led to an uncontrollable dive, the experts believe.
At that moment, the voice recorder is said to have registered a conflict between pilots. The pilot that tried to force the aircraft to gain altitude apparently turned the engines to powerful take-off mode, forcing the aircraft to continue its climb.
The other pilot believed the situation was dangerous and apparently did the opposite: he pushed his own control over to bring the Boeing’s nose down and prevent the sweeping up, while yelling at his colleague to stop doing it that way.
“Wait! Where are you flying? Stop! Stop!” a voice on the recorder reportedly yelled.
