The flight data recorder showed, that the airplane was touching down at a calibrated airspeed of 153 knots, an actual ground speed of 188 knots at a vertical speed of more than 1100 feet per minute resulting in a vertical acceleration of 3.09G. The airplane had been doing a 960 feet per minute sinkrate down to about 9700 feet (500 feet AGL) at a calibrated airspeed of 153 knots and 188 knots above ground. Then a pitch down command occured resulting in about 1500 feet per minute sinkrate descending through 400 feet AGL down to 200 feet AGL. At 130 feet AGL the sinkrate had reduced to 992 feet per minute, but increased again.
Now that's a hard landing...
Although I understand that the pilots should have aborted way before I'm not too sure to understand as why they hit so hard ? When you have a 1100 ft/m sinkrate why on earth would you add a pitch down command ?
