## Summary

We are revising an earlier proposed airworthiness directive (AD) that applies to certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. The earlier NPRM would have required you to inspect and, as necessary, adjust the aileron and rudder rigging and would have required you to modify, inspect, and, as necessary, adjust the rudder-aileron interconnect system. The earlier NPRM resulted from a jamming of the aileron and rudder controls on a Model SR20 airplane, which resulted in loss of rudder and aileron flight controls. Since issuance of the NPRM, CDC revised the service information as a result of comments received on the NPRM, and the FAA has determined the changes to the service information are necessary to address the unsafe condition. The changes in the revised service information include the addition of airplanes to the Applicability; a requirement to check rudder, aileron, and rudder-aileron interconnect rigging; a requirement to replace the attaching hardware and clamp at the end of the rudder- aileron interconnect arm; and an increase in work-hours to do the proposed actions. This proposed AD would require you to use the revised service information and would require you to report any out-of-rig condition found. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these additional actions.
