Magneto Overhaul Intervals

While Bendix magnetos can be infinitely overhauled, proper maintenance intervals are essential for reliable ignition system performance. The aviation industry generally recommends:

• 500-hour inspections: Required by AD 2005-12-06 (MSB645) for TCM/CMI/Bendix magnetos including internal timing verification
• Complete overhaul: Typically performed at engine overhaul (1,200-2,000 hours depending on engine model)
• Preventive maintenance: Regular external timing checks, ignition harness inspection, and spark plug maintenance
• Condition-based overhaul: If magneto shows signs of rough running, timing drift, or starting difficulties before scheduled interval
