There used to be a saying for microlights. There are those of us who have had an engine failure, and those of us who will.
My list:
3rd solo. Pop rivets holding in baffle on highly tuned 2 stroke fractured. Baffle fell into prop and shot up through the wing.
Self induced. Cut engine deliberately on 2 stroke twin after climbing to 8500 ft to glide down. Intention to restart at 1500 ft. Couldn't get it to pull start, and plugs were very rich and sooted on post landing inspection. No leaning possible.
Coil failed on one cylinder of 2 stroke twin, so partial only, but not enough power left to maintain height.
Rocker broke on 4 stroke twin. Ended up on Roedean hockey pitches.
Gearbox failed on 2 stroke twin. Engine still running fine.
Electrical failure on friends 2 stroke shortly after takeoff.
Paramotoring single 2 stroke engine stopped on final glide. No drama at all.
In all cases, the aircraft were undamaged. Some luck was definitely involved in a few, though.
