Edouard59,
If you post on here again, I would be interested in the logistics of getting your aircraft repaired assuming you are not based in the UK.
Reason I am interested is that a friend of mine based in the UK some years ago bent the front wheel of his (permit) Jabiru in France and, while the business of getting it repaired was not difficult, I think it took him nearly a year to get it back to the UK because of the difficulties of getting approval as it was classed as a homebuilt and, at that time, the engineers did not (or would not) cover work done outside of the UK. In his case he wanted to fly it back to the UK and found the legalities very frustrating. In retrospect he might have done better to take the wings off and ship it back but simply repairing the wheel and flying it back seemed, at the time, a lot simpler.
