I’ve been flying for 30 years and never experienced a hiccup from an airplane engine while airborne. That changed a few minutes into a recent flight. This story can’t rival a sudden engine stoppage and forced landing—it’s a story of an engine that seemed on its way to quitting—but I hope it provides some useful lessons.
Detonation Grounds a Mooney
Key Takeaways:
- A pilot experienced severe engine roughness mid-flight, prompting an immediate Mayday call and diversion to the nearest airport, where the engine recovered after the mixture was pushed to full rich.
- Investigation revealed a cracked spark plug insulator and suspected partial fuel injector obstruction in one cylinder, likely causing a lean mixture and a detonation event.
- Key takeaways emphasize the importance of immediate action (e.g., enriching mixture, declaring Mayday), making precautionary landings even if an engine recovers, and the critical value of engine monitors and moving-map displays like ForeFlight for safety.
