Airworthiness Directive · Amendment 39-16982 · Fuselage
Cessna Aircraft Company Airplanes
This AD applies to Cessna Aircraft Company Model 560XL airplanes; certificated in any category; serial numbers -5002 through -5372 inclusive, -5501 through -5830 inclusive, -6002 through -6080 inclusive, and -6082 through -6086 inclusive.
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 560XL airplanes. This AD was prompted by reports of jammed or stiff rudder control due to water freezing on the rudder bias cables and pulleys of the stinger. This AD requires modification of the drain installation of the tailcone stinger on the aft canted bulkhead, inspections for drain holes in the forward and aft frames, and modification of the drain holes. We are issuing this AD to prevent ice accumulation on the cables and pulleys of the stinger, which could result in jamming of the rudder and consequent reduced controllability of the airplane.
Within 800 flight hours or 12 months after the effective date of this AD, whichever occurs first: Modify the drain installation of the tailcone stinger on the aft canted bulkhead (i.e., install a drain and rubber seals), in accordance with the Accomplishment Instructions of Cessna Service Bulletin SB560XL-53-16, dated October 4, 2011.
For airplanes identified in Cessna Alert Service Letter ASL560XL-53-08, dated January 21, 2011: Prior to or concurrently with the modification required by paragraph (g) of this AD, modify the drain holes, including inspecting for a missing drain hole and, before further flight, drilling a larger drain hole as applicable; in accordance with the Accomplishment Instructions of Cessna Alert Service Letter ASL560XL-53-08, dated January 21, 2011.
Note 1 to paragraphs (g) and (h) of this AD: After accomplishing the actions required by paragraphs (g) and (h) of this AD, maintenance and/or preventative maintenance under 14 CFR part 43 is permitted provided the maintenance does not result in changing the AD-mandated configuration (reference 14 CFR 39.7).
Although Cessna Service Bulletin SB560XL-53-16, dated October 4, 2011; and Cessna Alert Service Letter ASL560XL-53-08, dated January 21, 2011; both specify to submit certain maintenance 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.
