Airworthiness Directive · Amendment 39-15318 · Cessna Model 680 Airplanes
Cessna Model 680 Airplanes
This AD applies to Cessna Model 680 airplanes, certificated in any category, serial numbers -0001 through -0152 inclusive, -0157, and -0158.
We are adopting a new airworthiness directive (AD) for certain Cessna Model 680 airplanes. This AD requires inspecting the routing of the aft fairing wire bundle assembly for adequate separation between the wiring and the hydraulic line; inspecting for chafing or damage of the wire bundle assembly and for damage to the hydraulic line, and doing corrective actions if necessary. This AD results from an incident report which indicated that a hydraulic leak and wire chafing, including signs of heat damage, were found within the lower tail cone fairing area. Similar wire chafing has also been found on other airplanes. We are issuing this AD to detect and correct wire chafing, and inadequate separation of the wiring and hydraulic line, which could lead to electrical arcing and a hydraulic leak and could result in a potential source of ignition and consequent fire.
Comply with this AD within the compliance times specified, unless already done.
Within 10 days after the effective date of this AD: Do a general visual inspection of the routing of the aft fairing wire bundle assembly for adequate separation between the wiring and the hydraulic line, and do a general visual inspection for chafing or damage of the wire bundle assembly and for damage to the hydraulic line; by doing all of the actions, including all applicable corrective actions, specified in the Accomplishment Instructions of Cessna Alert Service Letter ASL680-24-02, dated October 1, 2007; except as provided by paragraph (g) of this AD. Do all applicable corrective actions before further flight.
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 ensure visual access to all 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.”
Although the Accomplishment Instructions of Cessna Alert Service Letter ASL680-24-02, dated October 1, 2007, specify to submit certain information to the manufacturer, this AD does not include that requirement.
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.
