AD 2008-26-04 Airworthiness Directives; Cessna Model 560 Airplanes

Makes named: cessna. Models named: 560. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Cessna Model 560 airplanes, certificated in any category, serial numbers (S/Ns) 560-0001 through -0538 inclusive.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Restatement of Requirements of AD 2007-23-13 Airplane Flight Manual (AFM) Revision (f) Within 14 days after November 30, 2007 (the effective date of AD 2007-23-13), revise the Operating Limitations, Normal Procedures, Emergency Procedures, and the Approach and Landing sections of the AFM to include the information in the temporary changes (TCs) identified in Table 1 of this AD, as applicable, except as required by paragraph (k) of this AD. These TCs provide limitations and procedures for operating in icing conditions, for operating with anti-ice systems selected “on” independent of icing conditions, and for recognizing and recovering from inadvertent stall. Operate the airplane according to the limitations and procedures in the applicable TCs. Note 1: This may be done by inserting a copy of the applicable TCs into the applicable AFM. When these TCs have been included in the general revisions of the AFM, the general revisions may be inserted into the AFM (in lieu of the applicable TCs), provided the relevant information in the general revision is identical to that in the applicable TCs.

As of the effective date of this AD, only Revision 1 may be used. The placards must be installed above or near the pilot and copilot altitude indicators or primary flight displays and must be in clear view of the pilot and copilot. The placards may be removed when the actions specified in paragraphs (i) and (j) of this AD have been accomplished. No Maintenance Transaction Report Required for Cessna Service Bulletin (h) Although Cessna Service Bulletin SB560-34-143, dated September 7, 2007, including Attachment and Service Bulletin Supplemental Data; and Cessna Service Bulletin SB560-34-143, Revision 1, dated November 21, 2007; referred to in paragraph (g) of this AD, specify to submit a maintenance transaction report to the manufacturer, this AD does not include that requirement. New Requirements of This AD Terminating Action (i) Within 6 months after the effective date of this AD, do a functional test of the angle-of-attack (AOA) system, and adjust the calibration settings of the AOA system as applicable, in accordance with Cessna Alert Service Letter ASL560-34-34 (for airplanes equipped with a single AOA system) or ASL560-34-35 (for airplanes equipped with a dual AOA system), both Revision 1, both dated October 2, 2007, both including Attachments, as applicable; or Cessna Alert Service Letter ASL560-34-34 or ASL560-34-35, both Revision 3, both dated March 6, 2008, both including Attachments, as applicable.

This AD results from an evaluation of in-service airplanes following an accident. The evaluation indicated that some airplanes may have an improperly adjusted stall warning system. We are issuing this AD to prevent an inadvertent stall due to the inadequate stall warning margin provided by an improperly adjusted stall warning system, which could result in loss of controllability of the airplane.
