Nev,
Appreciating your comments, might I ask which other resin systems has
Europa validated as approved substitutes for SP Systems Ampreg 20? For a
substitute resin system to be approved it would require a structural
analysis, which would require the design load proprietary data to be made
available. Has Europa ever made this data available, and would they in the
future, and at what cost? So, if Ampreg 20 is not available any longer in
countries around the world other than the UK, with shipping and normal
delivery delays internationally delivering out of date product "off the
ship", being a very old resin system with known handling and using
hazards, what do you suggest as an alternative system? I am luckily in the
situation where all of my flight controls and flying surfaces have been
made with Ampreg 20, and I am using Ampreg 22 for the less critical layups
within the fuselage, but I am sure others may well like to hear your advice
on resin system substitutions pertinent to structurally critical areas.

P.S. Did SP Systems gain approval of Europa for the inclusion of a/c to be
pictured on the Technical Data Sheet of the new Ampreg 22 resin system?
