True, but this is a specifically-addressed exception to the requirement for 1 hour of ground training, so there's no need for a ground training log entry. OTOH, as far as a practical test is concerned, the FAR's specifically address practical tests saying that the examiner is acting merely an observer, not an instructor, and the DPE Handbook (an FAA Order) specifically prohibits giving instruction during a practical test. Since the examiner isn't acting as an instructor, and isn't giving training, there cannot be training log entry to make. However, the interpretation letter from the Chief Counsel's office clearly states that the examiner may sign the FR endorsement based on the events of the practical test, without saying the examiner must also give and log "training." Based on Administrator v. NTSB and Merrell, if Ms. McPherson says it's OK, it's OK, and that's the end of that unless one can show her interpretation is "arbitrary, capricious, or otherwise not according to law" -- and I don't see that happening on this issue.
Like I said, the basic idea that a successfuly completed CFI practical test doesn't sufficiently cover "the current general operating and flight rules of part
91 of this chapter" and "maneuvers and procedures that ... are necessary for the pilot to demonstrate the safe exercise of the privileges of the pilot certificate" to sub for a 61.56(a) FR is already utterly absurd, so any further absurdity is merely spitting in the ocean.
