What was found
BOTH MAGNETOS WERE REMOVED AS PART OF THE ANNUAL INSPECTION AND SENT TO NORVIC AERO ENGINES LTD (FAA APPROVAL 33NY343C) FOR THEIR 500 HOUR INSPECTION. THE MAGNETOS WERE RETURNED WITH 8130 PAPERWORK, RE-INSTALLED AND FOLLOWING COMPLETION OF THE ANNUAL INSPECTION BY THE IA, THE AIRCRAFT WAS RELEASED TO SERVICE. THIRTY MINUTES INTO THE SECOND 'POST ANNUAL' FLIGHT THE RH MAGNETO FAILED CATASTROPHICALLY (A LITTLE UNDER TWO AND A HALF HOURS AFTER INSPECTION). INITIAL EVIDENCE CASTS SIGNIFICANT DOUBT AS TO WHETHER THE MAGNETO WAS INSPECTED IN ACCORDANCE WITH THE MANUFACTURER'S MANUAL - OR EVEN AT ALL.
