Cessna 650 Citation III, Atlantic City, N.J., Oct. 27, 2007–The NTSB blamed this accident on the first officer’s failure to maintain airspeed during approach, and the captain’s inadequate correction. The first officer’s failure to comply with procedures, wind shear and the lack of wind shear warning from ATC contributed to the nonfatal accident.

The first officer was flying the Rnav GPS approach to Runway 22 at Atlantic City International Airport, and reported intermittent airspeed fluctuations between his airspeed indicator and the captain’s. The airplane was fast because of wind conditions. The first officer deployed speed brakes, then retracted them at about 200 feet agl. The airplane landed hard, driving the right gear into the right wing. The flight manual prohibited deploying speed brakes below 500 feet agl.
Although the Atlantic City Tower had given previous flights wind-shear warnings, it did not inform the Citation crew.
