## Discrepancy

UPPER DRAG BRACE PN 50-8100398 RUBBED AGAINST THE LOWER DRAG BRACE PN 508100404 AT THE KNUCKLE.  THIS REMOVED ABOUT .0625 OF AN INCH OF METAL ABOUT .0625 OF AN INCH LONG ON THE TOP SIDE OF BOTH ENDS OF THE KNUCKLE.  THE CAUSE IS IMPROPER MACHINING OF THE PART AT MANUFACTURE.  PARTS AFFECTED MUST BE REPLACED.  (K)
