Cessna 172 and Dassault Falcon 200, Teterboro, N.J., July 9, 2008–The NTSB blamed the Teterboro Airport (TEB) runway incursion on the ground controller’s failure to instruct the pilot of the Cessna 172 that was taxiing in after landing to hold short of Runway 24, on which the Falcon had been cleared for takeoff by the tower controller. The takeoff clearance was canceled and the aircraft came within 1,200 feet of each other.
