This pilot heard an impact sound during a night landing. It was followed with a failed brake antiskid indication.

He reports possibly hitting a foreign object on the runway. Inspection of the left gear revealed part of the tire heat shield (P/N 5004549-E) had torn away, cutting the brake antiskid wire harness, bending the gear door rod, and denting the inboard area of the landing light housing. Inspection of the right heat shield found it loose, but both shields (left and right) were installed correctly according to the Goodyear Components Maintenance Manual. The submitter states: “The tire heat shield has no ‘hard mount’ attachment to the wheel assembly. This problem is a common occurrence with Cessna Citations having this wheel/brake set up. Upgrading these aircraft to the newer style wheel/brake assembly is the only viable fix to prevent this from happening in the future.”
