## Discrepancy

EXTREME PLAY FOUND BETWEEN MAIN ROTOR PITCH HOUSING AND PITCH BEARING HOUSING. THE UPPER BOLT STILL HAD TORQUE STRIP APPLIED BETWEEN NUT WASHER AND BOLT BUT WAS LOOSE IN PIECES DUE TO THE WEAR. THE UPPER BOLTS ON TWO OTHER PITCH HOUSINGS WERE FOUND TO BE UNDER TORQUED BUT TORQUE STRIPED.
