## Discrepancy

(AUS) NOSE LANDING GEAR STEERING COLLAR FAILED AT THE STEERING ACTUATING MECHANISM ATTACHMENT LUG.   INVESTIGATION FOUND THAT THE CRACK HAD EXISTED FOR SOME TIME FINALLY FAILING DUE TO OVERLOAD.  THE COLLAR HAD GENERAL PITTING CORROSION.  FURTHER INVESTIGATION FOUND CRACKING ON THE OTHER ATTACHMENT LUG WHICH WAS NOT VISIBLE TO THE NAKED EYE.
