I was just going over a recently repaired airplane and found some enlightening things. I think many newcomers could profit from some of the things we find or see that might be an indication that something is not normal or just plain going wrong. It could be an observation in the shop or at the field.

Besides the obvious savings in money, time and anguish, there is alot of humor involved also that will help us to get over the shock of finding something that is NOT GOOD!

For example:

Everyone knows that:

Fuel dripping out of the tail wheel hole is NOT A GOOD THING
Dirt packed into the servo arm screws is NOT A GOOD THING
Smoke coming out of the battery hatch is NOT A GOOD THING

OK, here is my start. Tell us what you have found or seen that is NOT A GOOD THING!
