General information:

Uzbekistan Airways Technics aircraft maintenance enterprise (UAT) is a structural unit of the Uzbekistan Airways JSC, which has more than 90 years of experience in the maintenance and repair of aircrafts, engines and components. The UAT modern complex performs maintenance and repair of such aircrafts as the Boeing 757/767/787, Airbus 300/310/318/319/320/321 and their components.

Favorable geographical location of the Uzbekistan Airways Technics aircraft maintenance enterprise on the territory adjacent to the Tashkent international airport allows to receive, store, maintain and repair the aircrafts of any class. UAT Hangar aprons are connected to the Taxi Ways of Tashkent International airport in the name of Islam Karimov.

Give us a call and we will tell you about the full spectrum of works performed on all types of aircrafts. Welcome!



Uzbekistan Airways Technics (UAT) was established on November 12, 1924, when the Dobrolet Aviation Community launched the first aircraft maintenance workshops. The workshops provided maintenance services of K-4 and K-5 single-engine aircrafts, German Junker and Forman aircrafts, Junker and BMW aircraft engines. In 1937 Aircraft Repair Plant №243 of Civil Aviation, created on this basis repaired such types of aircrafts as: ANT-9, F-5, P-5, G-l, G-2, K-4, K-5, U-2, BMV-123A and L -5 engines. Later on, the maintenance of TB-3, Li-2 and M-17, M-34, ASH-62IR engines was mastered.

After the war the plant was equipped with new equipment for the production of civilian goods. For many years, in addition to Il-12, Il-14 and Yak-12 plant was specialized in the repair of the long-haul aircraft Il-62, transport aircraft Il-76, the first wide-body Il-86 aircraft, AI-25 engines and TA-6, TA-6A, TA-8 auxiliary power units.

After the war the plant was equipped with new equipment for the production of civilian goods. For many years, in addition to Il-12, Il-14 and Yak-12 plant was specialized in the repair of the long-haul aircraft Il-62, transport aircraft Il-76, the first wide-body Il-86 aircraft, AI-25 engines and TA-6, TA-6A, TA-8 auxiliary power units.

With the acquisition by the Uzbekistan Airways JSC air carrier of techniques of the Western production – the Airbus 310, the Boeing 757/767 and BAe146/AVRO146-RJ, aroused a need of development and maintenance, and in 1997 on the basis of the plant was established a centre for the maintenance of Western technique. As early as in 1998 the first in Central Asia C-check on one of the aircraft Airbus 310 was executed. Starting from the 1999 is performed maintenance in the C-check quantity of the aircrafts Boeing 767 and BAe146/AVRO146-RJ, and since 2000 – aircraft Boeing 757.

In 2002, the plant № 243 of Civil aviation was renamed into Uzbekistan Airways Technics aviation enterprise, and in 2006 it was complemented with the State unitary enterprise aviation technical complex, performing the maintenance of the aircrafts of Eastern production.

Having received some new aircrafts of the Airbus 320 type in November 2010, the professionals of UAT have performed the first A-check maintenance on the aircraft type, and in 2011 – С-check maintenance.

In 2016 on the basis of UAT was put into operation a workshop for the repair of composite aircraft components for the aircrafts of the latest generation, including Boeing 787 Dreamliner.
