KEY LARGO, FL, USA
N314QS
Cessna CE-560
The pilot completed the before landing check, which included the lowering of the landing gear, several miles on short final. The pilot recalled that the landing gear indicator lights were green, or landing gear down and locked. After the airplane landed, the pilot deployed the thrust reverses. At approximately the same time, the nose gear retracted into the wheel well. The airplane slid down runway 04, and came to rest 2000 feet from the end of the runway. The initial examination of the airplane disclosed that the nose gear up-down-lock actuator experienced a mechanical failure. During the subsequent examination of the assembly, no mechanical problem was detected during functional testing. All functional pressures and other operational parameters tested within the normal certificated limits.
