## Discrepancy

THE AIR CONDITIONER BELT GUARD FAILED IN FLIGHT.  INSP REVEALED 2 SMALL CRACKS AT THE LT SIDE WELDED NUT.  THIS FAILURE CAUSED A 2 INCH X 2 INCH STEEL PIECE OF THE BELT GUARD TO SEPARATE, STRIKE THE AIR CONDITIONER CLUTCH ASSY AND SHEAR THE CLUTCH ASSY, BOTH OF WHICH SUBSEQUENTLY DEPARTED THE ACFT.
