## Discrepancy

DURING THE PERFORMANCE OF AD-89-12-08 THE LT OUTBOARD HINGE LUG WAS FOUND CRACKED.  CRACK WAS VISUAL TO THE NAKED EYE, MICRO FRACTURES WERE NOTED LAST 200 HOUR INSPECTION BUT WERE NOT DEFINED.  SUGGEST THAT CAUSE COULD BE DUE TO EXCESSIVE RADIAL AND AXIAL LOADS TRANSMITTED TO THE HINGE DURING T/R APPLICATIONS.
