AD 2005-13-21

To prevent uncommanded movement of the horizontal stabilizer, which could result in reduced controllability of the airplane, accomplish the following:

(a) Within 12 months after the effective date of this AD, inspect to determine the part number (P/N) of the actuator control unit (ACU), in accordance with the Accomplishment Instructions of Cessna Service Bulletin SB 650-27-53, dated March 11, 2004. If an ACU having P/N 9914197-7 is installed on the airplane, then no further action is required by this paragraph. If an ACU having P/N 9914197-3 or P/N 9914197-4 is installed on the airplane, replace the existing ACU with a new, improved ACU having P/N 9914197-7, in accordance with the service bulletin. Although the service bulletin specifies to submit certain information to the manufacturer, this AD does not include that requirement.

(b) Within 1 month after the effective date of this AD or concurrently with the replacement required by paragraph (a) of this AD, whichever is first: Revise the Limitations and Normal Procedures sections of the AFM by inserting into the AFM a copy of all the applicable Cessna temporary revisions (TRs) listed in Table 1 of this AD.

Note 1: When a statement identical to that in the applicable TR(s) listed in Table 1 of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of the applicable TR may be removed from the AFM.

(c) As of the effective date of this AD, no person may install an ACU having P/N 9914197-3 or -4, on any airplane.

(d) In accordance with 14 CFR 39.19, the Manager, Wichita Aircraft Certification Office, FAA, is authorized to approve alternative methods of compliance for this AD.
