DURING A ROUTINE INSPECTION THE 247 BULKHEAD WAS FOUND TO BE CRACKED. THIS BULKHEAD IS THE ATTACHMENT POINT FOR THE FOREWARD END OF THE VERTICAL FIN, THIS PART WAS REPLACED WITH A NEW BULKHEAD 2150 HRS AGO, THIS STATION OPERATES A FLEET OF 16 PA-44-180S, ALL OF THE SAME SERIAL NUMBER RANGE, PURCHASED NEW FOR FLIGHT TRAINING, AND ALL OF THOSE WERE FOUND TO HAVE CRACKS IN THE SAME BULKHEAD DURING THE 2015-2016 TIME FRAME AT AN AVERAGE OF 7-9000 HRS. THE CRACKS OCCURE ON THE FWD SIDE DOUBLER UPPER RIVET ROW OUTBOARD RIVET. THE BULKHEAD EXHIBTS POOR WORKMANSHIP WITH THE -5 RIVETS BEING OVER DRIVEN WITH SIGNS OF RIVETS CREATING DIVITS IN THE DOUBLER, WHICH IS WHERE THE CRACKS ORIGINATE FROM. THE ORIGINAL BULKHEAD SHOWED THE SAME QUALITY OF WORK.
