## Discrepancy

(CAN) DURING VISUAL INSPECTION THE AME NOTICED A CRACK IN THE ADHESIVE BEAD OF THE STARFLEX ARM END BUSHING. FURTHER INVESTIGATION USING SOAP AND WATER (TO CREATE BUBBLES) CONFIRMED THAT THE END BUSHING WAS MOVING WHEN A LEADING/LAGGING FORCE IS APPLIED TO THE MAIN ROTOR BLADE, INDICATING THAT IT IS INDEED DEBONDED.
