Question: The situation is a flight instructor has asked the question
whether he can give a flight review in a tailwheel airplane and yet he has
not previously met the additional training requirements for operating a
tailwheel airplane [i.e., § 61.31(i)].

Answer: Ref. § 61.1(b)(2); § 61.56(c)(1); No, a flight instructor cannot
give a flight review in a tailwheel airplane unless he has complied with §
61.31(i). Per § 61.56(c)(1), it states, in pertinent part, ". . . by an
authorized instructor . . . ." Per § 61.1(b)(2)(ii), it states, in
pertinent part, ". . . in accordance with the privileges and limitations of
his or her flight instructor certificate . . . ." The flight instructor
would not be considered an "authorized instructor" for giving a flight
review in a tailwheel airplane.

Just because Lynch says it don't make it so. This has been
demonstrated to everyone's satisfaction multiple times. The FAQ is
neither regulatory nor authoritative.

Lynch is correct in that the definition of an authorized instructor is
given in 61.1(b)(2)(ii). The pertinent part is indeed ". . . in
accordance with the privileges and limitations of his or her flight
instructor certificate . . . ."

The privileges and limitations of a flight instructor certificate are
defined by 61.193 and 61.195 respectively.

61.193 Flight instructor privileges.
A person who holds a flight instructor certificate is authorized
within the
limitations of that person's flight instructor certificate and ratings
to give
training and endorsements that are required for, and relate to:
(g) A flight review, operating privilege, or recency of experience
requirement
of this part;

Note that it mentions only "flight instructor certificate and ratings"
and not a word about endorsements. Tailwheel is an endorsement, not a
rating. Note that it also says nothing about recency of experience,
medical requirements, or any of the other things that are relevant to
acting as PIC.

61.195 Flight instructor limitations and qualifications.
A person who holds a flight instructor certificate is subject to the
following
limitations:
(b) Aircraft ratings. A flight instructor may not conduct flight
training in any aircraft for which the flight instructor does not
hold:
(1) A pilot certificate and flight instructor certificate with the
applicable
category and class rating; and
(2) If appropriate, a type rating.

Once again, note that there is not a word about endorsements, recency
of experience, medical, etc.

In other words, Lynch is simply wrong. Again.
