About us

The history

Alain Zoller established Air Turquoise in 1995. He has tested glider since 1989 and he knows very well AFNOR and LTF standards from the beginning. Claude Thurnheer started to work with Alain in 1994 as a test pilot. They together have tested a lot of gliders and have built up solid competence of testing all type of gliders.
As the new standard EN (CEN) started to grow in 1994, we all knew this standard will come, but didn’t know exactly when. It took 11 years to develop EN standard before it finally got published in 2005. The working group (WG6) who were responsible for creating EN standard consists of national federations, manufacturers and test pilots. Every European country voted “YES” for EN standard.
Less than one year after the standard was released, in January 2006, Alain Zoller and Randi Eriksen started to develop at testing structure and procedure according to EN standard.
In March 2006, the infrastructure and people were ready and we could finally start testing after the new standard. We organized several “EN information-days” mainly for factory test pilots, so they could know and understand how the new standard was working and how they could prepare their glider before certification. 
Since 2006 Air Turquoise was certified by ISO 9001:2000 and we got ISO 9001:2008 in 2009. That means our management and administration are supervised yearly and following ISO 9001 standards.
In April 2009 Air Turquoise SA was an official LBA approved test house for type-inspection of aerial sports equipment according to German airlaw. This means Air Turquoise SA can test and certify paraglider equipment worldwide after EN standard and for Germany after LTF (2. DV LuftGerPV ).
Since 2010 Air Turquoise SA have two representatives in CEN / TC 136 / WG 6.
Germany change the rules for who can supervise the test house, so we had to obtain the ISO 17020 too. We got it in 2015.
In 2016 we are celebrating 10 years with EN standards.


We are 2.5 employees working in the office. The test pilots are working as a freelancer and they come to us for flight test. We have tested over 1500 gliders according to EN standard in all categories (A, B, C and D) and we are sure this standard works well. We still need to develop the standard in WG6 for paraglider, harnesses and emergency chute, so the working group in CEN still existing.
For us it is important to be open and transparent about certification and the way we are working. We work hard to satisfy all parties and we are always improving our performance.

EN 926-1:2015 Paraglider load test
EN 926-2:2013 Paraglider flight test
EN 12491:2015 Emergency Parachutes (rescue)
EN 1651:1999 and EN 1651:2018  Harness
