## Discrepancy

(AUS) LEFT MAIN LANDING GEAR NUT ASSEMBLY FAILED.  THE FAILURE WAS CAUSED BY A CRACK LOCATED APPROXIMATELY 31.75 (1.25 INCHES) FROM THE END OF THE NUT HOUSING EXTENDING FOR 360 DEGREES CIRCUMFERENTIALLY WITH 100 PERCENT PENETRATION.  FURTHER INVESTIGATION FOUND THAT THE NLG AND RT MLG NUT ASSEMBLIES WERE SIMILARLY CRACKED.
