Just experienced my first real-life engine failure in #GeneralAviation!
Luckily, as pilots always say: "checklists save lives", which is why we were able to detect and identify the issue *before* take off.
During run-up, when I tested the first magneto, the RPMs immediately dropped 200 and then kept falling until the engine started choking. I turned it back on before it died completely. We tried again to reproduce the result and then called ground control for a return to the ramp.
