Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Raytheon Model Hawker 800XP airplanes. This proposed AD would require inspecting to determine if the correct fuse is installed on the hydraulic over-temperature switch on panel ZK in the rear equipment bay, and replacing the existing fuse if necessary. This proposed AD results from a report of the installation of an incorrect fuse on the over-temperature switch on panel ZK in the rear equipment bay during airplane maintenance. We are proposing this AD to prevent a short circuit in the fuse and consequent heat damage to associated wiring and surrounding equipment, which could result in smoke or fire on the airplane.
