AC 23.143-1, which deals with tailplane stalls due to icing, mentions tail
configuration as one of the considerations but does not distinguish between
T-tails and conventional tails in its advice to avoid flap extension if
icing is suspected. No free pass for T-tails or cruciform tails.

The tail plane stall that all keep talking about, isn't it caused by
icing over a stablizer that is at or just below the plane of the wing?
Then when the flaps are deployed, the air is disturbed sufficiently
that the tail stalls?

Therefore, if flying a T tail (or similar), deployment of flaps should
not affect the tail. Is this correct?

I'm asking because of flying a Piper wherein the wing is actually below
the stabliator. Deployment of 15 degrees of flaps should not
sufficiently disturb the airflow to cause the tail plane stall in this
case. Is this correct?

ps. I'm almost at that 350hr mark some one else mentioned. T-storms,
fog and ice conditions are automatic no-go situations for me. Too much
at stake.
