Dan, the fundamental difference between our respective systems, as I'm sure has been mentioned before, is that in the USA you carry the responsibilities individually, for the approval and airworthiness of you're a/c whereas in the UK, the responsibility for approval is carried by the LAA and continued airworthiness is a partnership between us as builders/aircraft owners, our LAA inspectors and the LAA HQ Engineering Dept. Hence, unless we get individual approval for any mods (which do not come lighty) we do not have the same freedom for experimentation. On the other side of the coin, however, we do have a very worthwhile safety net of regulation and oversight.

So, I guess that if you were to build a "one-up", it would be as bad as building a new certified aircraft here in the US. Seems like a really good way to encourage "experimentation".

Serrano Jr.'; 'KRnet'; 'Flesner' Subject: Re: KR> UK aircraft grade lumber supplier? As Mike says. If you're flying under UK law it needs to be built as per plans which is what the design has been assessed against, unless it's a KR2S in which case it's as per plans plus some mandatory modifications which the LAA will send you drawings of. It is possible to modify from the plans, but mods need to be approved via a documentation package demonstrating by calculation their safety and integrity. Structural mods will also require physical load testing. Dudley Pattison of the Swindon Aircraft Timber Company was good, but I hear he's trying to retire. If built under UK law it needs to be built with Sitka Spruce and GL1 grade birch ply. You can use GL2 ply for non-structural stuff, but I can't think of anything non-structural on a plans-built KR2 off the top of my head. I would most strongly suggest you heed Mike's advice and contact the LAA for advice before proceeding any further.

It certainly will be an issue if you expect to build and fly your KR under the UK Light Aircraft Association's Permit to Fly arrangements. I suggest you look on the LAA website and find a local inspector to guide you through the system. <http://www.lightaircraftassociation.co.uk/inspectors/insp_home_page.html> http://www.lightaircraftassociation.co.uk/inspectors/insp_home_page.html There are several UK builders who occasionally post here and might offer you their advice.

I hope it will not be too much of an issue. _______________________________________________ Search the KRnet Archives at <http://tugantek.com/archmailv2-kr/search> http://tugantek.com/archmailv2-kr/search.
