Aircraft Advanced Radome Repair

To Aircraft Maintenance Repair & Overhaul (MRO stations and their composite repair technicians in the maintenance of Aircraft Radomes:

As an MRO composite repair station, an Aircraft radome is more than just a cover for your aircraft's radar unit. It's an integral part of your avionics system and some aerodynamics of the aircraft.
The radome is one of the most important parts of the airplane. It must be able to withstand the wind-, rain- and hail- forces of normal flight while providing a window through which the radar signal can be sent.
That's why all radomes need to be repaired following approved OEM repair specifications by very skilled Composite Repair Technicians. To repair your damaged Radome(s) by OEM specifications, you need skilled and well trained Composite Repair Technician(s) with many years of repair experience who can do the job accordingly.

Advanced Radome Repair requires far more added skills from a composite repair technician than he already has. In our training center in Amsterdam, we train you as an individual or as a company Composite Repair Technician in Advanced Radome Repair.

Our skilled instructor(s) are professional experts in advanced composite repair and specialized in all type radome repair. In this course, we will offer you a range of repair methods, techniques, which the instructors perform on a monthly base in-between course planning in assist of  Part 145 Certified Composite/Radome Repair companies based  in the Netherlands and Europe
We have the ability to train technicians in the repair of all type radomes such as surface erosion problems, extensive impact damage, full re-ring rebuilds, moisture ingress repair, and other repairs. Training in the fabrication of radome tooling for repair and re-ring or dome repairs is what we are best in.
Contact us for the course you or your company requires.
