Can’t tell if the plane is dangerous or not

200 hours in and when I’m flying this 172 at a flight school I struggle to maintain my altitude a lot of the times because the rpm will change +-100 rpm. It doesn’t happen rapidly but will change 10rpm every second or two, it happens every flight. I’ve never experienced this in a plane and I’m worried it is going to fail on me. Am I overthinking??

+/-100 RPM is normal and can be caused by any number of things, including just not being 100% level (which is basically impossible to do by hand). You're going to just have to get used to it. Make adjustments as needed. Be a pilot. We don't just set things and forget it.

As the PIC, you're the one that ultimately decides if it's safe to fly. Personally, I wouldn't go up with unresolved doubts about it. Don't want to end up on the news as the guy that crashed and redditors find this and point out "the guy knew it wasn't safe but went anyway".

Sounds like you are describing surging. Can be caused by numerous things. Regardless, it's a maintenance issue that needs addressed. Assuming the friction lock isn't slipping, the rpm should be maintained throughout. Squawk and walk.

i,ve walked away from several airplanes doing my preflight. Squawked them and rescheduled a different airplane for later.

200 hours in and and it happens every flight? But yet you've never experienced it? Something isn't adding up here.

Sorry I worded it better. I have 200hrs pic only about 10 hours in this plane

Sounds like throttle friction would fix that?

I got it as tight as it’ll go
