## Discrepancy

ON A FLIGHT THE ENGINE STOPPED SUDDENLY WITH NO WARNING. THE AIRCRAFT LANDED.  THE ENGINE ACCESSORY CASE HAD MAJOR DAMAGE.  THE MAGNETOS WERE BROKEN AWAY FROM THE CASE AND THERE WERE SOME LARGE HOLES IN THE CASE.  A TEARDOWN INSPECTION REVEALED THAT THE CRANKCASE GEAR WAS FRACTURED IN SEVERAL PIECES.  NOT ALL OF THE PIECES WERE FOUND.
