I had my first experience with hangar rash yesterday myself (in almost 1.5 years of working here). CTLS winglet against an A/C fan box on a hangar wall, left a small nail-head sized flat spot against the tip. No structural damage, I felt it happen and immediately stopped.
When the hangar rash happened, I had a group of ~20 JROTC kids with me that I was showing around the hangar and letting them look at the planes (without touching). I got a call from a tenant asking to fuel his plane (CTLS) and I asked if the kids could spot me since we were going back that way anyway (they cleared the wings and looked like they were). I pushed the tail down and turned to get around a car parked in the middle of the hangar and the winglet rubbed into the A/C unit.
Dumb move on my part expecting someone else to spot me. I had been moving at light speed all day to that point. I work alone every weekend but rarely are they that outrageously busy. As soon as the rash happened, I looked to see how bad it was, got the car driver to move it out of the way (should have done first) and got the plane to the pump, whereupon another mess unraveled itself that I had to go solve solo. I didn't tell the boss immediately because 1) day off 2) it wouldn't change the damage 3) the guy was showing up in an hour or two and I would tell him about it before he left and 4) I was a bit preoccupied with the 8 other things on my list I had to do ASAP. Someone else told my boss before I did and now my trustworthiness is in question.
The owner looked at the spot and told me that I shouldn't sweat over it and that he isn't upset - things happen.
The damage sucks and you have every right to be upset with the tug driver, but thank you for being accomodating. I hate that I damaged someone else's plane in any way, and I should've not trusted the kids to watch or even asked them to do it in the first place.
I pulled a twin cessna through the grass a few weeks ago by accident because it was parked too close to the edge of the ramp nose first. It rained the night before meaning the tug would sink. I couldn't push it back on my own, but I could pull it (slight incline). Turned it to the farthest it would go and tried to line it up on the tug so I could push it backwards and it ended up going too far and rolling into the grass. I had to move it so I could get another plane out and there was no other way to do it. A 2nd person would have made it possible to push it back far enough to get the tug on it but it was first thing in the morning and no mechanics were around and I was alone. I told the boss to tell the owner about it and that it was my fault.
We do not have a policy about moving aircraft with wing walkers for hangar or ramp movement. The mechanics are sometimes able to help make sure I don't hit anything.
Thank you for being lenient.
