What was found
DURING ROUTINE INSP, ADHESIVE BEAD FOR A STAR ARM END BUSHING FOUND CRACKED. FURTHER EXAMINATION UTILIZING A SOAP WATER DETECTION METHOD REVEALED RELATIVE MOTION BETWEEN BUSHING & STAR ARM END. WITH ROTOR HUB SLEEVES REMOVED, BUSHING COULD BE MOVED MANUALLY. A SERVICEABLE REPLACEMENT STARFLEX WAS INSTALLED. THIS IS A DEFECT THAT RECENTLY HAS BECOME MORE COMMON THAN IN THE PAST. SUGGEST A DIFFERENT ADHESIVE BE UTILIZED OR THE STAR ARM ENDS AND BUSHING BE DESIGNED TO HAVE A LARGER ADHESIVE BONDING SURFACE SUCH AS ADDING INNER BUSHING AND OUTER STAR ARM END SPLINING. NO EVIDENCE OF ANY IMMINENT FAILURE FOR PART OR EXCESSIVE PLAY DEVELOPMENT OF BUSHING. SUGGEST THAT APPLICATION OF A SLIPPAGE MARK BETWEEN STAR ARM AND BUSHINGS TO SHOW BUSHING ROTATION BE ADDED AS A PRECAUTION TO DETECT DANGEROUS MOVEMENT. (K)
