It gets really easy to miss something like that. I've not missed the landing gear - but something goes a bit sideways and you are out of practice - things get skipped. I've, for example, left the carb heat on when I had to go around. The hot summer air, combined with a C152 at max load, made for a hair raising takeoff. At 500' or so, the instructor casually asked if I was going to turn off the carb heat, which improves engine performance quite a bit. Figure I'll fly 30 or so hours this year. The normal workflows get rusty, which is why checklists are such a thing. When someone does a belly up landing, what usually ends up being the expensive part is the prop smacking the tarmac, the engine must be rebuilt. This is what it looks like from the inside. Notice the beep that the pilot... missed. https://www.youtube.com/watch?v=-K4QHpVXtxI https://www.youtube.com/watch?v=-K4QHpVXtxI
