Does anyone have a copy of OR know how to find the following document?

"I4-FVK/91 Standards for Structural Substantiation of Sailplane and Powered Sailplane Components Consisting of Glass or Carbon Fiber Reinforced Plastics” - LBA July 1991"

It should be a public paper of the German Civil Aviation Authority/LBA accepted by EASA for certification of small composite Airplanes. I have send a query on the LBA website already. If there is a better means of contact, please let me know.

Thanks for your help.

This same question was asked in a prior E-T thread... almost verbatim... and only 1 lukewarm answer was posted...

Composites certification approach for aircraft structures

Foreign specifications are difficult to procure.

A Google-search short list included this EASA document...

I have managed to get hold of a copy from the LBA. Just for information, this document forms the requirement basis for composite materials including the fatigue test requirements.
