Aviation
We have supplied the aviation industry since 2013. That called for a different way of working: traceability from material to final inspection, documented processes and a full measurement report with every delivery.
Which parts does Fijn Mekaniek Nelissen make for aviation?
Fijn Mekaniek Nelissen machines parts, replacement parts and prototypes for aviation, holding an EN 9100:2018 certificate under number BE014750. We work in metal and plastic, fully inspect every workpiece and supply the relevant certificates with the delivery.

Our EN 9100:2018 certification — technically equivalent to AS9100D — covers the machining of metals and plastics for the production and supply of parts, replacement parts and prototypes for the aviation, space and defence industries.
In practice this means we think along from the concept stage, assess the manufacturability of the design, produce to the specified tolerances and fully inspect every workpiece in our climate-controlled inspection room. Finishing treatments are handled by specialised partners — with a certificate.
It also means we like to be involved early. An aviation part that only reveals its weak spot at the first clamping costs weeks. If we are at the table during design, we bring that question forward, while a drawing is still cheap to change.

Frequently asked questions
Is Fijn Mekaniek Nelissen EN 9100 certified?
Yes. We hold an EN 9100:2018 certificate, certificate number BE014750. The certificate covers the machining of metals and plastics for aviation, space and defence.
Do you supply measurement reports?
Yes. Every workpiece is inspected with great precision in a climate-controlled inspection room, on equipment including a Mitutoyo Crysta-Apex V9208 and Wenzel 3D measuring machines. The necessary certificates are supplied with the delivery.
What is the difference between EN 9100 and AS9100?
They are regional versions of the same aviation standard. EN 9100:2018 applies in Europe and is technically equivalent to the American AS9100D. Our certificate states that equivalence explicitly.
Which materials do you machine for aviation?
Metal and plastic. The scope of our certificate is, word for word, the machining of metals and plastics for parts, replacement parts and prototypes for aviation, space and defence.
Can you advise on the manufacturability of a design?
Yes, and preferably early. We look at clamping, machining sequence and choice of material before the first chip is cut. At that point a drawing is still cheap to change; a rejected part is not.
