“This aircraft was here (repair station) for a complete exterior repaint,” writes the submitting technician. “After removing the rudder we complied with Cessna service bulletin SB MEB 00-4. It’s just a visual inspection, but it does require removing the rudder. We found the rudder hinge assembly (P/N 5731026-1) was installed upside down. Being in the aircraft refurbishment business...(and working) many of the effected model airplanes, we have found about 75 percent of these lower rudder hinge assemblies installed upside down, and many with the bearings falling out and wearing on the rudder hinge brackets. I recommend a one time AD to inspect all effected aircraft....”
