Not so sure what EASA/JAA would say about this but I fear if landing and takeoff performance with a Jet can be done with all respective marings I cannot see why "in theory" an AOC would restrict any operations because the only limiting factor is the crazy up/downslope and if that's do-able or not is defined by the AOM/POH and by no authority I would imagine. Nevertheless I don't see any Jet operating in there legally giving the short RWY of only 550m.
Not too long ago Tyrolean operated a Dash 7 into this airport
