Crashed Tu-154 sustained heavy impact force on landing

Russian investigators have disclosed the extent of the impact forces experienced by the Dagestan Airlines Tupolev Tu-154M which made an emergency landing at Moscow Domodedovo on 4 December.

Its initial contact with runway 32R resulted in a vertical load of 3.5g on the airframer, say the Interstate Aviation Committee (MAK).

This was followed by an impact of more than 5g in the subsequent landing contact.

MAK says it has derived the data from an on-board parametric register. The aircraft landed long on the runway, overrunning and breaking into large sections. There were two fatalities from among the occupants.

Russian investigators have not disclosed any further information regarding the whereabouts of the cockpit-voice recorder, which was not recovered from the site of the accident despite the lack of fire and relative integrity of the airframe.
