## Discrepancy

THE OPERATOR HAS A FLEET, SIX, OF THESE AIRCRAFT.  A PROBLEM HAD DEVELOPED CONCERNING THE CARBURETOR HEAT AIRBOX.  THE COVER IS ATTACHED WITH A PAIR OF SCREWS ON ONE SIDE AND A TONGUE AND SLOT ARRANGEMENT ON THE OTHER.  THE SLOTS WEAR OUT AT AN ALARMING RATE CAUSING THAT PART OF THE BOX ASSY TO DEPART THE AIRCRAFT.  IN A SHORT TIME, THE CLAMPS HOLDING THE AIRBOX BREAK AND AIR BOX FALLS TO BOTTOM OF COWL.  NEW PART BREAKS IN ABOUT 100 HOURS OR LESS.
