## Discrepancy

(CAN) UPON INSPECTING THE IGNITER,  IT WAS NOTED THAT THE CENTER ELECTRODE WAS MISSING. PORTION OF THE ACTUAL ELECTRODE EXPERIENCED A SEPARATION OF APPROX 6MM (1/4 INCH). THE DAMAGE CAUSED TO ENGINES HAS BEEN VARIABLE FROM ONE ENGINE TO ANOTHER, BUT THERE HAS BEEN NO REPORT OF POWER LOSS OR REDUCTION IN ENGINE PERFORMANCE. IGNITERS PERIODIC INSPECTION REQUIRES IN THE MAINTENANCE MANUAL EVERY 300 HOURS.
