The Yakovlev UT-1 (Russian: УТ-1) was a single-seater trainer aircraft used by the Soviet Air Force from 1937 until the late 1940s. The UT-1 was designed as a single-seater advanced trainer and aerobatic airplane by the team led by Alexander Sergeevich Yakovlev. The first prototype, designated the AIR-14, was flown in early 1936. The AIR-14 was a small low-winged monoplane with a fixed tailwheel undercarriage, with a welded steel fuselage and wooden wings. After some changes, the AIR-14 was accepted for production. Among other improvements, the 75 kW (100 hp) Shvetsov M-11 radial was changed to the more powerful 86 kW (115 hp) M-11G. The plane received the designation UT-1 (uchebno-trenirovochnyi {учебно-тренировочный}, primary/advanced trainer); despite this designation, it was not suitable for primary training.

The Yakovlev UT-1 was a single-seater trainer aircraft used by the Soviet Air Force from 1937 until the late 1940s. It was designed by Alexander Sergeyevich Yakovlev as a single-seater advanced trainer and aerobatic airplane. The first prototype, designated the AIR-14, was flown in early 1936. The AIR-14 was a small low-winged monoplane with a fixed tailwheel undercarriage, with a welded steel fuselage and wooden wings.
The UT-1 was not suitable for primary training, but it was used as a transitional type between the UT-2 and fighters like the I-16. It required precise piloting, thus forming an ideal intermediate between basic trainers and the maneuverable but difficult-to-fly I-16. The UT-1 underwent several modifications during its production, including changes in the engine, the fuselage length and the wing shape. Some UT-1s were also converted into improvised combat machines, fitted with machine guns or rockets, and used for reconnaissance or ground-attack missions during World War II.
The UT-1 was also used for setting several records before the war, some with its floatplane variant. In total, 1,241 aircraft were built between December 1936 and 1940. The UT-1 was replaced by the Yakovlev Yak-18 during the 1950s.
