## Discrepancy

THE MAGNETO COIL CRACKED CAUSING MAG TO FAIL.  THIS REPORT IS IN CONJUNCTION WITH AN ADDITIONAL REPORT ON THE SAME AIRPLANE AT THE SAME TIME A DUAL MAG FAILURE OCCURRED ON LANDING ROLL OUT.  INSPECTIONS ON THE NAGNETOS DO NOT REQUIRE REMOVAL OF COIL TO SATISFY INPSECTION, BUT IT WOULD BE HIGHLY RECOMMENDABLE TO DO SO.  SHOP HAS NOW FOUND 4 CRACKED SLICK COILS.
