NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE APPLICABLE TO ALL TELEDYNE CONTINENTAL MOTORS, BENDIX, AND SLICK AIRCRAFT PRODUCTS AIRCRAFT MAGNETOS REQUIRING: (1) THAT THEY BE REMOVED, DISASSEMBLED, AND INSPECTED IN ACCORDANCE WITH THE RESPECTIVE MANUFACTURERS PERIODIC MAINTENANCE INSTRUCTIONS AT THE NEXT ANNUAL OR 100-HOUR INSPECTION, AND AT EVERY 500 FLIGHT HOURS THEREAFTER UNLESS SUCH AN INSPECTION HAS ALREADY BEEN CONDUCTED WITHIN THE PAST 500 HOURS OF FLIGHT, OR THE MAGNETOS HAVE NOT YET ACCUMULATED 500 HOURS OF FLIGHT TIME; AND (2) THAT THEY BE OVERHAULED AT APPROPRIATE INTERVALS IN ACCORDANCE WITH THE MANUFACTURER'S MAINTENANCE GUIDELINES AND DETAILED OVERHAUL PROCEDURES.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an airworthiness directive for Teledyne Continental Motors, Bendix, and Slick aircraft magnetos. The directive would require removing, disassembling, and inspecting the magnetos at the next annual or 100-hour inspection, and every 500 flight hours thereafter, unless already inspected within the past 500 hours or the magnetos have fewer than 500 hours. It also requires overhauls at intervals specified by the manufacturer's maintenance guidelines and overhaul procedures.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
