Be aware also, that an inspector is required to show an ID (and for the FAA a badge nowdays), on a ramp check, and they have been known to swap ID's between 2 inspectors, and then fine the operator for failure to check. As it is a civil penalty, under USC 49, each event is a max fine of 10K, ie 20K fine just for acquiescing to their presence without checking docs.
So do they also get a fine - taken to court for fraudulent use of someone elses id ?
