Europa-List: Extension of outboard Tailplane pip pin holes?

[R.C.Harrison <ptag.dev@tiscali.co.uk>]

Hi! All
  I'm sensitive to all eyes being focused but quite independently from
the present furore I have been asked where the original suggestion came
---From re:- radially slotting the Tail plane pip pin holes to ensure they
imparted no drive but were only as retention pins.
My initial response was from a Europa Aircraft Tech Bulletin ..would
those who know for definite please confirm or otherwise.
