Preliminary Report: Confusion leads to hard landing

Cessna Citation 650, Atlantic City, N.J., Oct. 27, 2007–Citation N697MC came in “low and slow” on approach to Atlantic City International Airport and landed hard, substantially damaging the jet. The captain told the copilot to increase power, but the copilot “seemed confused” about different airspeed readings on the right- and left-side panel displays. He increased the power, but the airplane descended at an “abnormal sink rate” just as power began to increase. No one was injured.
