The flight was inbound to land, when the flight crew observed an unsafe nose gear indication. The crew was unable to confirm that the gear was down, and diverted to Runway 31R at JFK. The airplane landed on the runway, with the nose gear retracted, and an emergency evacuation was performed. Examination of the wreckage revealed the nose landing gear upper lock link was fractured into two pieces. The linkage jammed against the shock strut structure, preventing extension of the strut. According to the airplane manufacturer, the nose landing gear upper lock link failed due to fatigue. It was made from aluminum plating. Originally, all the links were made from forged aluminum. Then, the company used plated aluminum because it weighed less. Although both types of lock links were of the same strength, the aluminum plating fatigued sooner than the forged links. After the accident, the company replaced all aluminum plated upper lock links with forged ones.
Probable Cause: Failure of the nose landing gear upper lock link.
