Airworthiness Directive · Amendment 39-14455 · Raytheon Model Hawker 800XP Airplanes
Raytheon Model Hawker 800XP Airplanes
This AD applies to Raytheon Model Hawker 800XP airplanes, certificated in any category, serial numbers 258541, 258556, and 258567 through 258713 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Model Hawker 800XP airplanes. This AD requires 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 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 issuing 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 50 flight hours or 30 days after the effective date of this AD, whichever is first: Do a general visual inspection to determine if a 20-amp fuse is installed on the hydraulic over-temperature switch on panel ZK in the rear equipment bay in accordance with the Accomplishment Instructions of Raytheon Service Bulletin SB 24-3724, dated May 2005. If a 20-amp fuse is installed, before further flight, replace it with a 3-amp fuse in accordance with the Accomplishment Instructions of the service bulletin.
Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.”
Note 2: A note in the Accomplishment Instructions of the Raytheon service bulletin instructs operators to contact Raytheon if any difficulty is encountered in accomplishing the service bulletin. However, any deviation from the instructions provided in the service bulletin must be approved as an alternative method of compliance (AMOC) under paragraph (g) of this AD.
Where the Raytheon Service Bulletin SB 24-3724, dated May 2005, says to contact the manufacturer if any sign of damage is found on associated terminals and wires: Before further flight, contact the Manager, Wichita Aircraft Certification Office, FAA, for applicable repair actions; then, before further flight, accomplish the applicable repair actions specified, according to a method approved by the Manager, Wichita Aircraft Certification Office.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
