Asking an FAA inspector to inspect technical work is like asking a blind man to help you across the road !!
They do not have to have type courses on the aircraft they inspect !!
Sadly I have found this to be the case.
When operating an OZ registered A300-600 out of JFK a few years ago, we found some of them (not all of them) were next to useless.
One guy one night wanted to ground us because the shade of red in our emergency exit lights (normal shade in OZ) was a different shade of red to what he was used to.
Another one on the line one morning just prior departure snagged a crack in a main wheel I had only changed the day before, it was a brand new wheel directly from BF Goodrich in NJ, the "crack" was just a seam in the heat shield (NOT a crack at all obviously). It was just so stupid I tried to show him, but the Company didn't want to upset the almighty FAA, so we changed it for a similar wheel prior departure.
Cannot tell you here
what BF Goodrich said when they got this brand new wheel back under warranty because it was cracked. We refered them to the FAA expert.
