What was found
RECEIVED FACTORY REMANUFACTURED TSIO520 R9B FROM CAT. PRIOR TO REMOVING THE ENGINE FROM THE SHIPPING CRATE A PITTED AND MARRED LIFTER WAS DISCOVERED. ENGINE SN 1046657. CAT RETURNED THAT ENGINE AND SENT ME A REPLACEMENT ENGINE SN 1047255. PRIOR TO INSTALLATION IN THE AIRCRAFT IT WAS DISCOVERED ONE LIFTER WAS NOT ROTATING. CAT RETURNED THAT ENGINE. I THEN VISITED THE CAT FACTORY AND MET WITH THE CEO, DIRECTORS OF OPERATIONS, QA AND ENGINEERING TO DISCUSS THESE PARTS FAILURES. I HAVE RECEIVED A THIRD ENGINE AND ALL LIFTERS APPEAR NORMAL. I DON’T KNOW WHAT IS HAPPENING AT THE FACTORY BUT OBVIOUSLY THERE IS SOME SERIOUS LACK OF QA ISSUES AS EVIDENCED BY MY EXPERIENCE AND THE RECENT COUNTER WEIGHT AD.
