As Flug pointed out - one size does not fit all. There's a creeping tendency within EASA to treat a C-172 as if it were a B-727 and a PA-28 as if it were an MD-82. They're not, in exactly the same way that a Viking T1 isn't the same as a Hawk T1 - yet the MAA seem to think that they are.
I still think (as an ex-Air Cadet) that this sorry saga is truly shameful - and its not finished yet. Does anyone know if even a single Viking has been returned to service yet?
