Lufthansa Technik and NAS-Holding of Saudi Arabia are expanding their relationship. Since the two companies signed a 10-year cooperation agreement in September 2010 Lufthansa Technik has supported NAS’s technical business, NAS-Tech, in developing capacity for maintenance and smaller overhauls. Lufthansa Technik has also taken over maintenance services for the engines and components of the entire NAS fleet. Under the terms of the expanded relationship, the partners join forces in offering technical services, allowing them to take on the complete technical care of entire fleets from production monitoring to the start of flight operations.
