Plain English Summary

2/10 complexity

This safety directive requires owners of specific Cessna Citation II business jets (serial numbers 0002 through 0128) to inspect and potentially repair the cabin door frame.

The Safety Issue: The rivets connecting the door frame to the aircraft body may be positioned too close to the edge of the metal material. This "marginal edge distance" weakens the structural connection and could lead to failure of the door frame attachment.

Required Action: Operators must follow the detailed technical instructions in Cessna Service Bulletin 550-53-3, Revision 4 to:

Inspect the affected rivets where the fuselage frame meets the aft door post
Perform modifications or replacements if the rivets are found to be inadequately spaced

Who Must Comply: Anyone operating a Cessna 550 model aircraft within serial numbers 0002–0128. The aircraft cannot be considered airworthy until these steps are completed.
