What was found
BROKEN BOLT FOUND ON RT MLG DURING SCHEDULED 100 HR INSPECTION. THERE ARE 2 OF THESE BOLTS IAW ASSY. THE AFT OF THE 2 WAS BROKEN WITH THE FWD BOLT STILL IN TACT. THIS IS A FLIGHT SCHOOL ACFT, SO PROBABLE CAUSE IS EITHER HIGH AMOUNT OF LANDING CYCLES, A HARD LANDING, OR BOTH. TO PREVENT FURTHER OCCURENCE IS TO REPLACE THESE BOLTS EVERY 1000 HRS TIS OR DURING REMOVAL/REINSTALLATION OF MLG ASSY, WHICHEVER OCCURS FIRST.
