This article provides a scholarly analysis of the STAL-2 aircraft, which was developed in the 1920s–1930s during the early stage of light aviation in the Soviet Union. The study examines the historical background of its creation, structural features, technical characteristics, and operational use in short-distance passenger and postal transportation. The contribution of the STAL-2 to aeronautical engineering experience and its role in advancing affordable and easily maintainable aircraft models is also discussed.
