Such a scheme would be great to see but I fear it will never happen... As you mentioned previously, existing LAA courses may be an equally useful route. t's early days yet - I think we'll see clearer by Jan 2010 when everyone has had an ARC renvewal under the Full weight of EASA rules and approvals.
I'd like to be able to do some of the more basic tasks myself, and have a couple of group members who are reasonable at this sort of thing. They don't have a 'ticket' as such, but have some years of experience in mechanical matters.
The idea that we'd have to do a college course to gain accreditation for work we are already doing (and tasks we'd like to do) is tricky as these seem ony to be for professionals.
I'm hoping for the LAA route but so far this is under-resourced and not covering the subjects we'd want to do. But its early days yet.
