## Discrepancy

DURING A DAILY INSP, CRACKS WERE NOTED ON MAIN ROTOR STARFLEX IN ADHESIVE BOND FILLET THAT BONDS THE BUSH ONTO THE STARFLEX ARM.  THERE WAS NO INDICATION OF A BOND SEPARATION OR GAP BETWEEN THE BUSH AND STARFLEX. UTILIZING THE PROCEDURE FROM MM 62.20.00.601 PARAGRAPH 7A.  TEST WAS PERFORMED BY APPLING THE ROTOR BRAKE AND FLAPPING THE BLADE AND LEADING AND LAGGING BLADE TO CHECK FOR BOND SEPARATION BETWEEN  BUSH AND STARFLEX ARM.  WITH NO MOVEMENT OR DISBONDING NOTED TO BUSH SLEEVE ASSY WAS THEN REMOVED TO FURTHER INSPECT THE BUSH.  BY GRIPPING BUSH WITH THE HAND IT COULD BE ROTATED ABOUT .0625 OF A TURN THUS CONFIRMING A DISBONDED BUSH WHICH IS CAUSE FOR REPLACEMENT OF STARFLEX ASSY.
