Why don't you contact them directly?
Anyway, within 2-3 years there will by 23 new EC-135 in Poland. It looks like the legal battle between Agusta and EC has ended, and the national HEMS operator will get new machines, to replace the old Mi-2s. The only problem will be pilots. In my opinion they will have to look for around 80 additional, maybe more.
Regarding maintenance issues, I don't have any information. We'll see.
