What was found
DURING ROUTINE INSPECTION WITH ROTOR HEAD SLEEVE ASSY REMOVED ONE OF THE STAR ARM END BUSHINGS WAS FOUND TO TURN SLIGHTLY WITH HAND PRESSURE APPLIED. THE STARFLEX WAS REMOVED FOR REPAIR OF BONDING DEFECT. THIS IS A COMMON FAILURE FOR THIS PART. THE MFG CLAIMS TO HAVE A REPAIR FOR THIS DEFECT BUT OFFERS ONLY AN EXCHANGE ASSY. SUGGEST A NEW ADHESIVE SYS OR PART DESIGN BE TRIED TO REDUCE THIS TYPE OF DEFECT FOR AN EXPENSIVE PART. A SLIPPAGE MARK PAINTED ACROSS THE EDGE OF THE BUSHING AND ONTO THE STAR ADHESIVE BEAD HELPS IN DETECTION OF THIS DEFECT WHILE IN SERVICE BY INDICATING THE BUSHING HAS TURNED. (K)
