Cédric Zermatten - Management


I have known Mr Weedon since 1992 when we worked together as a team inspecting parts for F18 fighter aircraft in Switzerland.  When Mr Weedon and a colleague founded QualiTest NDT in 2000, they employed me as their Nominated Level 3 to oversee the Aviation activities carried out in accordance with EASA Part 145 regulations.  I have worked with them since that date and know them to be a high quality organisation striving to achieve the highest possible standards of inspections.
