## Discrepancy

FITTING FOUND CRACKED DURING POST FLIGHT INSP.  A NEW FITTING MATCH DRILLED AND INSTALLED.  THIS IS A COMMON DEFECT FOR THIS PART AND OCCURS MULTIPLE TIMES ON SOME AC AND NEVER ON OTHERS FOR REASONS UNKNOWN.  SOME SHIMMING IS SOMETIMES REQUIRED AND IF DONE POORLY THIS MAY AGGRAVATE THE CRACK DEVELOPMENT.   (K)
