I am posting the following for my local glider operation:

"Our Pawnee has two airworthiness certificates, one for normal flying
and one, restricted, for towing. When towing it is operated with
specific limitations spelled out on *an operators handbook supplement.
Our tow pilot believes that our Scout should also have a second
airworthiness certificate for towing and refuses to tow with it until it
does. I need to find another operation that tows with a Scout and get
their take on it before I approach the FAA for a finding. My take on it
is that it left the factory with a provision for a tow hook so the
standard airworthiness certificate covers it."

Anyone have an answer to this?

Ask the factory

We no longer own one, but towed with a Scout for many years.
