What was found
COMPLIED WITH MFG MEB 00-4 RUDDER BEARING INSPECTION/REPLACEMENT. FOUND RUDDER LOWER HINGE BEARING BRACKET INSTALLED UPSIDE DOWN FROM FACTORY. REPLACEMENT PROCEDURE DESCRIBED IN MEB FOUND ERRONEOUS AND INADEQUATE TO COMPLETE SATISFACTORY REPLACEMENT OF BRACKET. MS 2047AD4-11 AND AD 5-11 RIVETS CALLED OUT IN MEB ARE OF THE INADEQUATE LENGTH. THIS WILL REQUIRE -12 OR -13 LENGTH RIVETS. REPLACEMENT PN 5131010-3 IS NOT SAME SIZE AS ORIGINAL AND DOES NOT APPEAR TO HAVE ADEQUATE EDGE DISTANCE FROM RIVET HOLES AS WELL AS CAUSING BULGING OF VERTICAL STABILIZER SKINS BECAUSE IT IS SLIGHTLY TOO WIDE. A MAJOR RE-WRITE OF THIS MEB AND ITS COMPLIANCE INSTRUCTIONS IS NEEDED.
