Accidents: Hydraulic warnings cited in Citation overrun at JFK

Cessna 750 Citation X, New York, N.Y., April 3, 2008–On landing at John F. Kennedy International Airport, the copilot of WM Aviation’s Citation X said he did not have nosewheel steering, brakes or any feeling of engine thrust reverse at about 80 knots. Despite emergency air brake application, the jet veered off the runway and collided with a dirt divider, shearing off the left main landing gear and buckling the nosegear. The left wing dug into the sand.

The download of the airplane’s engine indication and crew alert system revealed a series of hydraulic abnormal indication warning lights. Both crewmembers stated they completed the checklist procedures for the warning signals and lowered the main landing gear, thinking the problem was solved. No one was injured in the incident.
