I can't be the first to ask this one! I am about to embark on a D140 project. Is there LAA approved equivalent material spec for those given with Jodel plans:

Steel:
XC18 at 42 Kg/mm (squared)
A56 3e at 56 -------//-----------
25CD 4 at 68 -------//----------- ( 4130??)
30NC 11 at 85-------//-----------
45 S8 at 150-----??-----------

Aluminium/ Alloy:
AU4G at 40 Kg/mm ( squared) "plaque A5"
AG3 at 19 ---------//-----------
AS13(sable) at 17----//---------

Thanks, Mark

Suggest you ask the question on the Jodel Yahoo group which is the successor to the Jodel Club.
