What was found
THE THRUST REVERSER ASSY HAS STIFFNER ANGLES THAT GO AROUND THE BARREL. THE POINT WHERE THE ANGLE ATTACHES IS CRACKED AT ONE LOCATION. SEVERAL OTHER THRUST REVERSER ASSY WERE EVALUATED ON AIRCRAFT IN HOUSE AND NO CRACKS WERE NOTED. IT APPEARS THAT THE ANGLE IN QUESTION WAS PRELOADED AND DRAWN DOWN TO THE CARRIAGE RATHER THAN BEING SHIMMED.
