The basic idea here is to implement the "principle of one-stop shop." That is, the GSS offers operators SSJ-100 all they are interested in a package of services, and with anyone other than the GSS, the airlines do not have to talk. It's like a person who has bought a new foreign car for a dozen years in advance sure that he does not need to jump on the Dealers in search of parts of questionable quality, and all the questions he will be able to decide in a decent service center. As a man, the airline will be able to accurately plan the costs required to maintain the airworthiness of the aircraft during the entire period of its operation. This SCA will be responsible for managing the technical support process, allocating the necessary work between manufacturers of components and authorized service centers. And the Italian Alenia Aeronautica will organize after-sales service SSJ-100 abroad, using its extensive experience and infrastructure existing in servicing aircraft ATR-42/72.
