## Discrepancy

THE PILOT REPORTED A ROUGH ENGINE THAT RESULTED IN A PRECAUTIONARY LANDING.  THE INITIAL INSPECTION REVEALED THE NR 1 CYLINDER FUEL INJECTOR LINE WAS BROKEN IN TWO AT THE NOZZLE END.  THE FLIGHT SCHOOL OPERATES A FLEET OF 8 M20J AIRCRAFT. AD 93-02-05 IS ALWAYS C/W AT EACH 100-HOUR INSPECTION.  THIS IS A COMMON FAILURE, AND VERY DANGEROUS.
