Russia’s first production-standard MC-21-310 passenger aircraft has returned to the Irkutsk Aviation Plant after completing an extensive testing programme at the Gromov Flight Research Institute in Zhukovsky, near Moscow. The aircraft will now undergo passenger cabin installation, which is a further important step toward the eventual delivery of the domestically produced narrowbody jet to Russian airlines.
The aircraft, carrying factory number MS.0014 and registration number 73362, arrived in Irkutsk on November 3, 2026, following the completion of its work in Zhukovsky. The aircraft will be prepared for its next production and certification activities by the specialists at the Irkutsk Aviation Plant, a subsidiary of Yakovlev within the United Aircraft Corporation (UAC).
The aircraft’s return is noteworthy due to its use in the assessment of the MC-21-310’s production-standard configuration, which includes Russian-developed equipment and systems. The testing program has examined various critical components and systems of aircraft, such as their functionality in various operational environments.
From the first flight to the Zhukovsky testing
The maiden flight of the first production-standard MC-21-310 was successfully completed on August 3, 2026, at the Irkutsk Aviation Plant. The aircraft maintained an altitude of up to 6,000 meters and instrument speeds of up to 600 km/h for a duration of one hour and 23 minutes.
Russian test pilots Roman Taskaev, Sergey Mikhailyuk, and Andrey Voropayev, along with test engineer Nikolai Fonurin, were responsible for the flight. The crew assessed the aircraft’s controllability in various configurations, stability, and the operation of its domestically developed onboard systems during the flight.
Immediately following its successful maiden flight, the aircraft was prepared for transfer to the Moscow region for additional testing.
The MC-21-310 departed Irkutsk for the Gromov Flight Research Institute airfield in Zhukovsky on August 13. The aircraft’s maximum speed was approximately 850 km/h, and it reached an altitude of 12,100 meters during the five-hour and 50-minute flight.
The aircraft was piloted by Russian test pilots and Heroes of Russia Roman Taskaev and Oleg Kononenko, with onboard operator Alexander Popov. Taskaev subsequently reported that the aircraft’s systems had operated without any reported issues throughout the voyage.
What Was Tested During the Zhukovsky Programme?
The aircraft was stationed at Zhukovsky from August until its return on November 3, a period of approximately 82 days away from its manufacturing base.
The aircraft underwent additional evaluations as part of the certification program during this time. The aircraft was subjected to testing in various seasonal conditions, such as winter and summer operations, as per the information released by the Irkutsk Aviation Plant.
Russian-developed systems and equipment were installed on the aircraft with particular attention to their performance. Assessments were also conducted under precipitation conditions and during long-distance flights.
These activities were crucial for the successful establishment of the operational characteristics and reliability of the aircraft’s domestically sourced components. The interruption of Western equipment supplies necessitated the replacement of numerous foreign-developed systems with Russian alternatives, resulting in significant alterations to the MC-21 program.
The aircraft has successfully completed this specific stage of evaluations at Zhukovsky, as demonstrated by the return of MS.0014. Nevertheless, the manufacturer has not publicly disclosed the cumulative flight hours or total number of test flights conducted by this particular aircraft over the course of an approximately three-month period.
Therefore, it is crucial to differentiate its testing program from the more extensive MC-21 certification campaign, which comprises several additional aircraft.
The other flight-test aircraft in the program have proceeded to assess the operational functions, flight characteristics, and individual systems. Collectively, these activities facilitate certification compliance.
This initial production-standard aircraft has thus contributed to the validation of the configuration and manufacturing procedures, in addition to the broader certification initiative.
Passenger Cabin Installation Next
The installation of the aircraft’s passenger cabin will be the immediate priority upon its return to Irkutsk.
The aircraft’s configuration during the trial phase was designed to simplify the tests that were required. The installation of the passenger interior will bring it closer to the configuration necessary for its eventual airline operations.
The manufacturer has also stated that additional modifications may be implemented if necessary. Before determining whether further modifications are required, specialists will initially consolidate and analyze the results of the certification tests.
This is a critical phase, as the results of the testing can pinpoint areas that necessitate modification prior to the aircraft’s transition to operational readiness.
The installation of the passenger cabin should not, however, be interpreted as confirmation that all certification requirements for the MC-21 program have been fulfilled. the aircraft’s individual testing activities and the overall type certification process are related but different.
Production Programme Moves Forward
The first production-standard MC-21-310 is a component of a more extensive initiative to establish the aircraft’s regular production in Irkutsk.
The manufacturing organization’s readiness to start aircraft production with the updated domestic configuration was demonstrated by the successful maiden flight in August. UAC had previously said that the Irkutsk facility was preparing for an initial production batch of 18 aircraft.
In the interim, progress is being made on the development of the next production-standard aircraft. On August 31, the flight-test division at Irkutsk received the second serial MC-21-310, which was assigned the factory number MS.0015, for the purpose of ground preparation and subsequent flight testing.
The development of multiple production aircraft is crucial for the purpose of improving the manufacturing experience, validating assembly processes, and preparing the industrial infrastructure for larger-scale deliveries.
The MC-21 is one of the most important and significant projects in the Russian aviation industry to establish an independent domestic capability in the medium-haul passenger aircraft segment.
In conclusion,
The return of MS.0014 to Irkutsk signifies the end of a critical testing phase that began with its maiden flight on August 3. The aircraft will now proceed to the installation of the passenger compartment and any requisite modifications, following the completion of seasonal evaluations, icing checks, and domestic system assessments. Next challenge is the conversion of the progress made by the first production-standard aircraft into a repeatable manufacturing and delivery process.
