What was found
FITTING FOUND CRACKED DURING POST FLIGHT INSP AND A NEW FITTING MATCH DRILLED AND INSTALLED. THIS IS A COMMON DEFECT FOR THIS PART AND OCCURS MULTIPLE TIMES ON SOME AIRCRAFT AND NEVER ON OTHER AIRCRAFT FOR REASONS UNKNOWN. SOME SHIMMING CAN BE REQUIRED AND MATCH DRILLING THE PART MUST BE DONE CAREFULLY. IF THE INSTALLATION IS NOT DONE CAREFULLY THIS MAY BE A FACTOR IN CRACK DEVELOPMENT AS WELL. (K)
