## Discrepancy

AIR FILTER SUPPORT, MADE OF A CYLINDRICALLY SHAPED WIRE SCREEN WAS FOUND TO HAVE THE SCREEN MATERIAL BREAKING AT THE JUNCTION OF THE RADIAL TO VERTICAL WIRES.  CAUSING, IN SEVERAL INSTANCES, TO SHED SECTIONS OF THE WIRE, UP TO AN INCH LONG.  WHEN THESE WIRES SHED, THEY ARE ALLOWED TO FALL INTO THE INTAKE AIR STREAM, AS THEY ARE INSIDE THE FILTER.  THIS COULD ULTIMATELY ALLOW THEM TO BE INGESTED INTO THE ENGINE.
