The C of A for G-APSA shows as Transport (Passenger) so that answers one question.
As far as I know both the Air Atlantique aircraft were gutted no seats and no pressureization fitting in them so the aircraft would be flight level restricted meaning a higher fuel burn on some long flight,
G-APSA when seen in Jersey has the cabin with very little in it so the chances of the aircraft reverting back to carrying passengers would be at a large cost.
With her C of A due April 2008 she might be changed to a pernit to fly only which would bring engineering costs down to keep her iin the air being flown at air shows.
It would be a shame but at least every one who is able to go to an airshow where the aircraft is would hopefully see her where she belongs in the air.
We still await the outcome of G-SIXC if she will find her way back into the skies over the U.K. and Europe.
