## Discrepancy

ENG NR 1 STARTED BACKFIRING NUMEROUS TIMES WHILE IN CRUISE FLIGHT, AFTER 1 VIOLENT BACKFIRE, THE ENGINE WAS SHUTDOWN AS A PRECAUTION SO AS TO NOT DAMAGE THE ENGINE EVEN MORE.  A NORMAL LANDING WAS PERFORMED.  NO DAMAGE AND NO INJURIES AND THE MAGNETO WAS REPLACED AND ENGINE GROUND RUN SERVICEABLE.
