Belyavskiy was not initially planning to compete in the 2017 Russian National Championships due to kidney stone problems, however he decided to compete anyway. He did not compete in the all around competition, showing routines on every event except rings in the qualification round. Balyavskiy was unable to defend his nation title on parallel bars as he did not qualify for the event final, however he did win his first national titles on pommel horse, with a score of 14.3, and high bar, with a score of 13.8. He also placed 5th in the floor final with a score of 13.5. Belyavskiy was then named to the team for the 2017 European Championships. At these championships, Belavskiy performed well, winning gold on the pommel horse, getting bronze on the horizontal bar, and placing fourth on the parallel bars.
