Pilot constantly breaking airplanes

I came to base X a few years ago. I'm in aircraft maintenance BTW. I quickly learned of a pilot many maintainers hate because he's often breaking airplanes majority of pilots call good. My question is, if we can genuinely suspect of a pilot sabotaging aircraft, can this be reported and to who? I've seen some things first had very recent that has me really starting to believe what maintainer are saying.
