What was found
FOUR NEW M/R GRIP BEARINGS WERE RECEIVED FROM BELL HELICOPTER. A MECHANIC CLEANED THEM PRIOR TO PACKING WITH GREASE AND ON ONE BEARING FOUND THAT ONE ROLLER WAS MISSING, A SECOND BEARING HAD 7 ROLLERS THAT WOULD NOT ROLL IN THE CAGE (APPROXIMATELY 1 INCH SPAN). THIS SHOWS THE IMPORTANCE OF INSPECTING PARTS PRIOR TO INSTALLING EVEN THOUGH THEY ARE NEW.
