"demonstrably incorrect" That's a new legal term, I just made it up ... like it?
What I meant by that is the cases where John Lynch's "FAQ's" have been unambiguously in direct contradiction to a chief counsel interpretation. This has hapened, some have been fixed, I can't say for sure that any still exist, but it's ceratinly a possibility in the future. My point is this: If I were an FAA inspector faced with a potential enforcement situation and I have a Chief Counsel interpretation in one hand and John Lynch's FAQ in the other and they are contradictory, I would have a difficult time rationalizing chosing the guidance in the FAQ over the legal interepetation. That seems to be what you are suggesting.
I share your thoughts on having consistent enforcement, but I disagree that John Lynch is the answer. The problem is a result of FAA inspectors overstepping thier authority and "interpreting" based on what they think the regulations ought to mean, not what FAA counsel says they say. In that sense, John Lynch is just another part of the problem, an FAA empolyee wth no official authority taking it upon himself to issue his own interpretations.
The issue of enforcement standardization is important, but unless the soulution comes from, or is tightly coordinated with the Chief Counsel, It's just adding one more layer to the problem, not solving it.
