## Discrepancy

DURING ROUTINE MAINTENANCE ON DUAL MAGNETO, A CRACK WAS FOUND ON THE RIGHT IGNITION COIL OUTER INSULATION COVERING.  THE CRACK STARTED FROM THE HIGH TENSION OUTLET CLIP AND RAN ALONG THE MOLD LINE APPROX .25.  BOTH SIDES OF THE CLIP HAD THE SAME TYPE OF CRACK, TWO ALTOGETHER.  MAGNETO OPERATION WAS NORMAL PRIOR TO INSPECTION.
