French Air Force maintenance


The French Air Force – l’Armee de l”Aire – awarded MK Test a contract to provide testing equipment for the force’s aircraft maintenance under its Maintenance, Repair & Overhaul (MRO) programme. This takes in service aircraft, stripping them down for a major overhaul that checks a substantial number of components, including the wiring looms and harnesses throughout the aircraft.

The specific requirements of the overhaul procedure meant the customer asked for a system that delivers Automatic Programme Generation, with multibus testing, in a portable, modular format. The latter issue was solved by MK Test, through its Special Projects Division, creating a series of modular, portable cabinets that can be easily carried around an immobilised aircraft, and used in multiple units as required by the testing programme.
