Applies to Models 210K, 210L, 210M, 210N, T210K, T210L, T210M, T210N and Model P210N airplanes certified in all categories which have the King Radio Model KFC-200 autopilot installed in accordance with the Supplemental Type Certificates (STCs) SA1202CE or SA1487CE and have the roll axis servo actuator mounted in the right outboard wing. COMPLIANCE: Required as indicated unless the requirements of Paragraphs A)1, 2 and 3 have been previously accomplished. To prevent loss of roll axis flight control: A) Prior to further flight: 1. Gain access to the right wing aileron bellcrank by removing the aft cover plate on the underside of the wing between wing stations 155 and 172 in accordance with the appropriate Cessna service manual. 2. Visually inspect the clevis bolt and nut which secures the autopilot bridle cable and the aileron cable to the aileron bellcrank to verify there is a cotter pin installed to secure the nut.3. If a cotter pin is installed, reinstall the cover plate and comply with Paragraph B. 4. If no cotter pin is installed, further visually inspect the clevis bolt to determine if the bolt was cross drilled for a cotter pin. 5. If there is a cotter pin hole and the nut is still in place, install an AN380-2-2, or equivalent, cotter pin and reinstall the cover plates. 6. If there is no cotter pin hole, replace the clevis bolt with a proper AN23-15, or equivalent, bolt as defined by Advisory Circular AC43.13. Reinstall the washers between the cable end fittings and install the nut and cotter pin. After securing the nut and cotter pin, re-rig the aileron system in accordance with the appropriate Cessna service manual and adjust the bridle cable to 20 2 pounds tension.
