To Aircraft Maintenance Repair & Overhaul (MRO stations and composite repair technicians in the maintenance of Aircraft Radomes:
For 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 aeroplane.
The Radome is one of the essential parts of the aeroplane. It must withstand the wind, rain, and hail forces of routine flight while providing a window through which the radar sends a signal.

All radomes are repaired in accordance with approved OEM specifications by skilled, well-trained Composite Repair Technicians. 
To repair damaged Radome(s) according to OEM specifications, you need to be skilled with many years of repair experience to do the job correctly.
That is where we come in to provide you or your technicians with the best skill training and knowledge! 
Composite Shop Managers and Shop leads need to understand that Advanced Radome Repair requires far more advanced skills than they already have as an actual Composite Repair Technician.
Our training centres in Amsterdam and Leipzig, Germany, train you as an individual or as a Composite Repair Technician in Advanced Radome Repair.

Our skilled Instructor is an expert in advanced composite repair and specializes in radome repair, with 3 decades of experience in full nose and ring job replacements.
This course will provide you with a range of tips and techniques for radome repair methods.
Aircraft types like Boeing 787, Boeing 777, Boeing 747, Boeing 737, Airbus A320,  Airbus A330, Airbus A350, Airbus A321, Airbus A350, Fokker 50-100, Embraer, and many more

To Aircraft Maintenance Repair & Overhaul MRO stations, Composite shop, their manager, and composite repair technicians in the maintenance of Aircraft Radomes:
For 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 aeroplane.
The Radome is one of the essential parts of the aeroplane. It must withstand the wind, rain, and hail- forces of routine flight while providing a window through which the radar sends a signal.

That's why all radomes are repaired in accordance with approved OEM repair specifications by skilled, well-trained Composite Repair Technicians with over 5 years of repair experience. 
To repair damages on Aircraft Radomes according to OEM specifications, you need to be skilled with years of repair experience before you can do the job accordingly.
That is where we come in, providing you, as a composite technician, with the best skill training and all the knowledge available. 

Composite Shop Engineers, Managers, and Shop leads need to understand that Advanced Radome Repair requires far more skills than they already have as an actual Composite Repair Technician.
At our training location at INSPIRE SSA Aircraft Maintenance (a Part 145/Part 21G/J org.) in Frankfurt, Germany, or on-site, at your facility, we train you as an individual or as a company in Advanced Radome Repair.

Our skilled Instructor is an expert in advanced composite Radome repair and specializes in Radome repair types, with 3 decades of experience.
In this course, we will offer you a range of repair methods and techniques that we, as instructors, perform every month between class planning to assist a Part 145 organisation in HEICO Germany. Certified Composite/Radome Repair company based  in the
We can train technicians to repair all types of radomes, including surface erosion problems, extensive impact damage, complete re-ring jobs/rebuilds, moisture ingress repairs, and other related issues.
For the technician, encourage your technician or their manager to contact us to enroll in this unique course. Your repair skills are what you or your company need for repairing advanced Radomes.
