I used the checklist this time. Step by step. When I enabled the first engine to start, it began to spin up as normal. The N1% ran up to 105%. After about 10 seconds, it all goes quiet. Dead quiet. Like it shut off. The blades don’t spin. Go to the 2nd engine, same thing. It’s like it’s over-revving. I checked all my bindings and I can’t see a conflict. May be a setting is causing this. ?
