Reply to Daerman ATC
I tried on the net to find the source of the BBC radio documentary claim, similar to the one in your Spanish link, that AEAS/EASA were concerned about the safety record of FlightlineBCN but I drew a blank.
I decided to approach AESA direct by email but they replied to the effect that "SAFA data" is confidential and not theirs to release but is the property of the country organisation which generates it.
They did however inform me that in recent years FlightlineBCN has been inspected within the EU as follows:
2009 Belgium
2010 France X2 and Germany
2011 France and Ireland.
