Russian investigator MAK has revealed that a nose-down push on the Boeing 737-800’s control column coincided with a nose-down movement of its horizontal stabiliser as the aircraft transitioned from a go-around climb into a steep, high-speed dive to impact.
The aircraft, operating the 19 March scheduled flight FZ981 from Dubai to Rostov-on-Don, Russia, was smashed into tiny pieces by the impact, and there were no survivors among the 62 people on board.
Earlier the MAK had stated there were no mechanical or systems failures revealed by the flight data recorder, but says it is still recovering components of the aircraft’s longitudinal control system to check there were no undetected anomalies.
The fatal approach to runway 22 took place at night in convective weather and windshear near the airport. MAK says a go-around was initiated at 220m altitude, and the nose-down yoke push and pitch-down motoring of the stabiliser occurred at 900m, while the cloudbase was recorded as 630m.
With each MAK data release, more similarities with the accident involving a Tatarstan Airlines 737-500 crash at Kazan in November 2013 are being revealed.
