Rebalance of the elevator shall be accomplished every 60 months. APPROVAL Cessna received FAA approval for the technical data in this publication that changes the airplane type design. Cessna received EASA approval for the technical data in this publication that changes the airplane type design. MAN-HOURS Negligible when accomplished during routine inspection periods. MATERIAL The parts below are available from Cessna Service Parts and Programs through an appropriate Cessna Service Facility. NOTE: All parts listed below are non-foam filled. Part Number Description Qty/Airplane Trailing Edge Assembly, Right Inboard Trailing Edge Assembly, Left (includes Tip) Trailing Edge Assembly, Right Outboard (includes Tip) Trim Tab Assembly Trim Tab Assembly Trailing Edge Assembly, Left Trailing Edge Assembly, Right Inboard Trailing Edge Assembly, Left Trailing Edge Assembly, Right Outboard 1 ACCOMPLISHMENT INSTRUCTIONS 1. Do a visual inspection as follows: A. Do a visual inspection of the elevator trim tab for corrosion, cracks, and security. Make sure that you look carefully for indications of internal corrosion (pin holes, discoloration, cracks). If there is SEB85-7 Revision 3 Page 2 June 25, 2013

5 evidence of internal skin to foam separation, soft spots, paint blisters, unsealed edges of exposed foam, deterioration of foam, or corrosion, you must replace the assembly. (1) If you must replace the trim tab assembly, replace it with a tab that is not foam filled. (2) if you must replace the trim tab assembly, refer to the Material section of this Service Bulletin for the part number, and refer to the applicable airplane Service Manual for replacement instructions. B. Do a visual inspection of the attachment of the trim tab bracket to the trim tab. Make sure that the rivets that attach the trim tab bracket to the trim tab are secure. C. Do a visual inspection of the trailing edges of the elevator for indications of internal corrosion damage or separation of the foam core from the skin. Make sure that you look carefully for indications of internal corrosion (pin holes, discoloration, cracks). If there is evidence of internal skin to foam separation, soft spots, paint blisters, unsealed edges of exposed foam, deterioration of foam, or corrosion, you must replace the trailing edge. (1) If you must replace the trailing edge assembly, replace it with a trailing edge that is not foam filled. (2) If you must replace the trailing edge assembly, refer to the Material section of this Service Bulletin for the part number, and refer to the applicable airplane Service Manual for replacement instructions. D. With a flat-bladed screwdriver, do a check for security at each rivet that attaches the actuator bracket to the trim tab as follows: (1) Put the flat edge of the screwdriver blade against the junction point of each rivet head and the skin surface. (2) With the palm of your hand, lightly tap the handle end of the screwdriver. (3) If there is any movement of one or more of the rivets, the structure has been compromised, and you must replace the trim tab. (4) Now put the flat edge of the screwdriver blade against the junction point of the bucked side of each rivet and the skin surface. (5) With the palm of your hand, lightly tap the handle end of the screwdriver. (6) If there is any movement of one or more of the rivets, the structure has been compromised, and you must replace the trim tab. 2. Rebalance the elevator in accordance with the applicable airplane Service Manual. 3. Make appropriate airplane logbook entries stating compliance and method of compliance with this Service Bulletin. If applicable, also note when the next repetitive inspection is due. SEB85-7Revision3 June 25, 2013 Page 3
