Willowrun, could you please enlighten some of us regarding the meaning of: ....Recomended Corrective Action....... and ...NCAs should ensure.... (not: SHALL ensure) Is that an order to EU member States that MUST be executed, or is this still a reccomendation, allowing individual Member State to decide on its own. I am over 30 years in aviation, but this language to me looks like a proverbial "wooden stone" that I cannot understand. (I am not an English native speaker)
