Further explanation by EN working group coordinator Hannes Papesh
The EN Standards 926-1 and 926-2 itself will remain unchanged. There were only some comments added to clear up some issues and some points adapted to the practical requests. As well there were some translation errors into German corrected. These comments are agreed by all the test centres (Air Turquoise, Aerotest, Academy and DHV). It's a working instruction how to deal with the existing En 926-2, not a change of the norm. A change would have taken too long, as well as all agreed, that it's too early to rebuild The EN-standard, as we have not enough practical experience with it yet.
Our working groups keep on working and a reconstruction of the EN-Standards is projected for the next 2 years (so valid maybe by the the end of 2011).
It will be a big change (not only in Germany), off course.
We all have to think in A, B, C, D now! (1, 1-2, 2, 2-3 are gone).
It was time to do this step! We're a small scene, we need to work together and don't need more than one test standard. The old expert's system of the LTF (the test pilot is the expert and can decide on his own responsibility) is not applicable for the situation of having more than one test centre. A documentary system is needed like the EN (clear, accurate descriptions, as good as possible documentation), to ensure, that you will get similar results wherever a wing is tested.
A big advantage as well is, that the manufacturer is enabled to do a better prediction of the results of the certification.
The expert in the LTF system was very free to decide. So you never knew in advance. Now the rules are clear for everybody.
I would like to thank everybody involved in that process!
