Approach and Flare
The captain reported a normal, stabilized approach with 28 degrees of flaps and a Vref speed of 133 knots plus 5 knots. During the flare over the runway, the sink rate was not being arrested as desired. The pilot then executed a more aggressive pull on the control yoke while advancing the thrust levers a significant amount.
Touchdown and Impact
The aircraft touched down hard on the runway. Digital flight data recorder (DFDR) readout revealed that airspeed remained above Vref+5 knots until 238 feet radio altitude, where it was 138.75 knots, then began to drop. At touchdown, airspeed was 124.75 knots with a pitch attitude of 10.62 degrees nose up. A vertical acceleration spike of +5.54 G was recorded.
Damage
The hard landing resulted in substantial damage to the aircraft.
