Aircraft Advanced Radome Repair

Course code: TECH-120
Course duration: 5 Days


To MRO stations and their Composite repair technicians:
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.
The radome is one of the most important parts on 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) that can do the job accordingly. Advanced Radome Repair requires far more added skills from a Composite Repair Technician than he already has.
