What was found

FOUND RIGHT LOWER AFT ELASTOMER PAD BROKEN LOOSE FROM THE NODAL BEAM. SUBMITTER STATES THIS IS A COMMON OCCURRENCE ON ENTIRE FLEET. IT APPEARS THE OIL AND GREASE IN THIS AREA CONTRIBUTES TO THE BREAKING LOOSE OF THE BOND SURFACE. THIS WOULD STOP IF A BETTER DESIGNED NODAL BEAM FLEXURE ASSY WAS USED OR A BETTER BOND MATERIAL WAS USED.
