## 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 replace the cabin door rod ends at the upper and lower hinges of the cabin door with newly designed rod ends. The earlier NPRM resulted from two known occurrences of in-flight cabin door separation (one total separation and one retained by the door strut). This proposed AD would require you to replace the cabin door rod ends with new parts including a redesigned non-binding hinge pin that replaces the existing pin at the upper door hinge. 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.
