## Discrepancy

DURING AN ANNUAL INSPECTION IT WAS FOUND THAT THE MAIN ROTOR SWASHPLATE WAS FREE TO MOVE VERTICALLY TOWARD THE FRONT ABOUT .7500 OF AN INCH.  THE ROOT CAUSE WAS SLOP ON MOST OF THE BEARINGS OF THE MIXER BUT THE WORST WAS ABOUT THE PIVOT POINT OF THE LATERIAL BELLCRANK.  REPLACED UNIT WITH A SERVICEABLE PART.
