It might be normal but it shouldn't be.
Keep in mind however that a small discrepancy or even a multitude of small discrepancies do not automatically make an airplane unsafe or unairworthy.
The pedal anti-slip rubbers come of all the time so glue and some tie-wraps do the trick.
A once every 10 sec fuel droplet is not instant catastrophy either, mind you it needs to be fixed but not necessarily right here right now.
How many times have you "pre flighted" your car?
Yet you take it onto the motor way every day.
Before the war starts, I know thats not aviation etc etc etc but you have to be realistic about discrepancies; is it safe? Is it legal? If yes on both
then it's the PIC decision to fly or not.
You can't expect a school or club to patch up every scratch, there's not enough of a profit margin to do so.
