## Discrepancy

ON A ROUTINE 100 HOUR INSPECTION, IT WAS FOUND THAT THE FUSELAGE LONGERON WAS CRACKED UNDER THE MAIN LANDING GEAR ATTACH BOLT ON RIGHT GEAR LEG.  THESE ARE THE SAME BOLTS THAT REQUIRE RE-TORQUE SETTINGS EVERY 100 HOUR INSPECTION.  AMERICAN CHAMPION IS AWARE OF THIS FAILURE AND PRODUCES A SERVICE REPAIR KIT PN: SK 233 AS DETAILED IN THEIR SERVICE LETTER SL96.  REPAIR DRAWING 4-1530 DETAILS THE REPAIR PROCEDURE.
