What role does the SMS play in achieving the goals facing aviation equipment designers in the civil aviation? For example, MS-21 aircraft characteristic features are emphasized at JSC Irkut Corporation website, contributing to its promotion to the markets [1]:

"The maximum economic efficiency of operation, international certification in accordance with the requirements of IAC AR, EASA, FAA and our individual logistics support and support throughout the life cycle, should make the product attractive to both Russian and foreign companies - operators”.

The goals set in the civil aviation should be achieved in conditions of ensuring a modern level of safety, corresponding ICAO [2], ultra-safe system (i.e., a system in which the number of catastrophic failures in ensuring safety is less than one per million production cycles).

Developed at the initiative of the world's leading aircraft manufacturers and supported by state certification organizations, the system approach to safety is implemented by ICAO in the form of a Safety Management System (SMS), a systematic approach to safety management that includes the necessary organizational structures, responsibilities, policies and procedures.

Safety Management System (SMS) is a systematic approach to safety management that includes the necessary organizational structures, responsibilities, policies and procedures.

Safety Management:

1. a)    includes all activities;
2. b)    focuses on processes with a clear distinction between the processes and the resulting consequences;
3. c)    based on data;
4. d)    includes continuous monitoring;
5. e)    being documented;
6. f)     it is aimed at gradual improvement, not abrupt changes;
7. g)    based on strategic planning rather than piecemeal initiatives.

Design Assurance System includes the following basic procedures related to the process of an aircraft sample design:

1)  product design;

"Design Management" procedures should include:

• main stages of the design process;
• work carried out at each stage;
• analysis of the impact of :
• airworthiness requirements;
• process requirements;
• market situation;
• economic and production conditions.
