THIS APU HAS A HISTORY OF BROKEN ITEMS IN THE LAST 30 DAYS THE OIL PRESSURE SWITCH WAS FOUND BROKEN, CHIP DETECTOR MAGNET FOUND MISSING, SPEED SENSOR REPLACED.  ALL HAVE BEEN REPLACED AND THE AIRCRAFT RELEASED FOR RETURN TO SERVICE. PICTURES FOR THE AFT MOUNT ONLY ATTACHED AS THE PREVIOUS FUEL BOWL PICTURES ATTACHED TO THE PREVIOUS SDR. (TC# 20190619002)
