July 20, 2010 SB09-27-0 1AR3

Dear Cessna Owner: This Owner Ad visory is to inform you that SB09-27-01 Revision 3 Rudder Hinge and Bracket Inspection has been issued. The paragrap hs that follow give a historical summary of previously issued revisions: A visual inspection of the lower rudder hinge or bracket and the upper and middle rudder brackets shall be accomplishe d for cracking, deformation, or localized discoloration. If any of these conditions are found, the affected hinge/bracket shall be replaced as stated in this Service Bulletin. SB09-27-01 Revision 1 provided a new design hinge and brackets for installation when replacements were required for the previous design parts. The new hinge and brackets are made of different material, incorporate a machined shoulder for enhanced bearing retention, and include the application of corrosion protection primer and a top coa t of white paint. SB09-27-01 Revision 2 included a modification kit for replacement of the brackets/hinges, instructions for rudder travel verification, an allowance for utilizing different length hardware to ensure adequate thread engagement, and instructions to verify proper hardware thread engagement of previously installed brackets and hinges. Additionally, Revision 2 is FAA-approved as an Alternative Method of Compliance for AD2009-09-09. SB09-27-01 Revision 3 adds airplane serial numbers that had the new-design hinge and brackets installed at the factory. These added airplane serial numbers are required to be inspected to verify rudder travel and for correct hardware thread engagement. Modification Kit MK400-27-01 has been revised to include two larger rudder travel stop bushings. Additionally, SB09-27-01 Revision 3 is FAA approved as an Alternative Method of Compliance for AD2009-09-09. Non-compliance with SB09-27-01 Revision 3 could allow any of the above described conditions to exist and if not corrected, may result in failure of more than one hinge or bracket which could potentially result in the loss of ru dder control.
