The Altai Tyre Combine and YASHZ Avia LLC have successfully completed qualification testing of tubeless radial tyres designed for the MC-21-310 and Superjet 100 aircraft. The development, which began as a proactive initiative in 2016, became a priority in 2022 when reliance on imports became critically important for the industry. This was reported by the “Altapress” publication.

The tyres created, size 1050x385R482, fully meet the requirements of PJSC Yakovlev. This tyre was the first experience for the combine’s specialists at all stages of manufacture. Preliminary tests, conducted in China in 2023, allowed for adjustments to the working design documentation of the tyres at the initial stage of developing the nose and main tyres for the MC-21 aircraft.

Positive test results for the MC-21 nose landing gear tyre were obtained in October-November 2024. Successful tests of the main landing gear tyres were completed in December 2024 and March 2025. This ensured successful completion of qualification tests in the PRC at the first attempt this year.

Currently, the enterprise is preparing for certification. To launch mass production, it is necessary to obtain a Certificate of Airworthiness for a Component (СГКИ, SGKI) for three sizes: 1050x385R482 mod. 1A, 770x240R-356 mod. 1A and 1260×450 R-559 mod. 1A. At the same time, a tyre for the Superjet 100 nose landing gear is being developed – the first prototype is scheduled to be manufactured by the end of 2025.

The SGKI is a mandatory document for aviation components, confirming their compliance with safety requirements and operational standards. Its receipt means that the product has passed all stages of testing and can be used in the mass production of aircraft. For aviation tyres, certification includes verification of load characteristics, wear resistance and compatibility with specific aircraft models. In Russia, the SGKI is issued by Rosaviatsiya (the Federal Agency for Air Transport) based on tests according to AP-25 standards.

“The completion of testing and preparation for certification is a significant milestone for the industry,” noted Vladimir Balabanov, General Director of JSC PO ASHK. “This not only reduces import dependence, but also creates a technological foundation for future projects.”

The success of the Altai engineers demonstrates the possibility of a complete cycle of production of critically important aviation components in Russia.
