So the in house check airman is not a DPE? I was under the impression that as far as CFI ratings were concerned there were only a few states that allowed DPE's to give the ratings. All other states were done through a FSDO, I haven't been current on CFI matters for a while but this was also second hand information to me at the time. I never actually saw a source proving in house examiners were not allowed to give the ride. That is interesting stuff right there.
