The crash of FlyDubai Boeing 737 in Russia's Rostov-on-Don could occur after the commander of the aircraft deliberately sent the airplane into the ground, PravdaRu reported.



"During the preliminary investigation it was found that the commander of the Boeing 737-800, presumably giving account for his actions and adequately assessing both the situation and the position of the aircraft relative to the ground, was holding the control knob for 12 seconds, thus putting the stabilizer into the nosedive mode," Interfax news agency reported with reference to its source.



Based on the data obtained from the flight recorder, the commander of the Boeing 737 was not answering questions from the co-pilot about the appropriateness of his actions. He would answer briefly and calmly: "All is well" and his intonation was calm, the source also said.



Previously, it was reported that the pilots of the FlyDubai aircraft had a conflict prior to the crash. Allegedly, after one of the pilots made a mistake in maneuvers, his partner tried to take control of the wheel.



In turn, a representative of the Interstate Aviation Committee said that the committee did not have the information to prove that the commander of the aircraft was acting voluntarily. A piloting error remains the basic version of the investigation, the official said.
