The most nitpicking fool I ever encountered was a PFA inspector (about 7 years ago).
He had not been engaged by me to inspect my aircraft but just happened to be in the hangar where my (then) Europa was kept - apparently with a measuring tape, a penchant for crawling around hangar floors and a little spare time on his hands.
He left a note for me inside my aircraft because the lettering on the wing of my aircraft was 1" too small. It should be amended immediately.
Of course I took immediate action, did sweet FA and laughed my socks off!!!
Good to know that although most CAA, FAA and PFA(now LAA) inspectors are sensible, pragmatic people there are still some jobsworths out there.
