Key Takeaways:

Many reported aviation incidents involve spark plug failures, frequently due to high or infinite electrical resistance values.
Physical damage, such as cracked insulators or broken spark plug bodies, is another common failure mode observed across various aircraft engines.
These spark plug issues often lead to engine roughness, elevated cylinder temperatures, performance degradation, and can contribute to more severe engine problems or operational shutdowns.
