SIMILAR INSPECTIONS OF THE MAGNETOS SHOULD BE CONDUCTED AFTER EACH 50 HOURS OF FLIGHT UNTIL DESIGN CHANGES NECESSARY TO PRECLUDE MAGNETO CONTAMINATION AND ELECTRICAL ARCING HAVE BEEN INCORPORATED.

The FAA is asked to issue an airworthiness directive covering specified Cessna models with Slick model 6220 and 6224 magnetos, requiring an inspection for contamination or electrical arcing within the next 10 flight hours and correction of any deficiencies. Similar inspections must be repeated every 50 flight hours until design changes to prevent contamination and arcing are incorporated.
