You cannot dictate where fuel is bought, you can dictate who fuel is bought from at a particular location. The former is competition law and neither A&BC, nor the fuelling guy are allowed to dictate what fuel goes in to an aircraft, ONLY that fuel sold at the airport can come from one company.
The rule has been put in because the council are scared of litigation and the fuel guy is just posturing because he can. The Law Lords only ruled on who can supply fuel at the airport not that fuel purchased elsewhere can be put in aircraft
Airworthiness is the responsibility of the owner or operator of the aircraft and no-one else.
What a bunch of fools, I got a nice PM from a guy asking me to come to Oban, I may still but honestly until it becomes a nice wee aerodrome again - why bother, there's lots more places to go
