Russia’s effort to revive regional aviation with an entirely domestically powered aircraft has reached another important milestone. The certification of the nine-seat LMS-901 Baikal light multipurpose aircraft, which is equipped with the indigenous VK-800SM turboprop engine, is expected to be finalized in the third quarter of 2027, according to Rosaviatsiya chief Dmitry Yadrov. At the Innoprom-2026 international industrial exhibition in Yekaterinburg on July 6, Yadrov said that the certification campaign had reached its definitive phase.
The timeline is the latest schedule for one of Russia’s most closely monitored civil aviation programs, which is designed to replace the outdated Antonov An-2 fleet that operates in remote regions. The Baikal aims to serve as the foundation of regional “last-mile” air transport, connecting isolated communities where larger aircraft are economically unfeasible while also accommodating nine passengers on short and unprepared airstrips.
Growing Demand for Regional Aircraft
Russian airlines have already indicated a need for 69 Baikal aircraft through 2035, as per Rosaviatsiya. The demand highlights the need for modern utility aircraft to service remote areas in Siberia, the Far East, and the Arctic, where aviation is often the only year-round transportation option.
The Baikal has been designed as a multifunctional platform that is capable of performing a variety of tasks, including cargo transport, medical evacuation, aerial surveying, agricultural operations, and emergency response missions, in addition to serving as a passenger aircraft. It is expected that its operational adaptability will render it a direct successor to the legendary An-2, which has fulfilled these functions for decades.
Domestic Powerplant Becomes the Centerpiece
The current development phase is dedicated to the integration of a Russian-only propulsion system that comprises the AV-901 propeller and the VK-800SM turboprop engine. This work is being conducted under the “LMS-5” research and development program, which was funded by a government contract awarded to the Ural Civil Aviation Plant (UZGA) by the Ministry of Industry and Trade of Russia in April 2025.
The contract, which is valued at over 10.3 billion rubles, encompasses the redesign of the aircraft to accommodate the domestic engine, the completion of the full certification campaign, and the preparation of all necessary documentation to secure type certification. The program is expected to be completed on December 17, 2027, which is in close alignment with the certification timeline that Rosaviatsiya has announced.
After western sanctions disrupted access to foreign components, Russia was compelled to redesign various civil aviation programs around domestically produced systems, thereby making the transition to a completely indigenous powerplant a strategic priority.
Flight Testing Progress Continues
The Baikal, which is equipped with the VK-800SM engine and AV-901 propeller, commenced flight testing on December 24, 2025, from the airfield in Yekaterinburg operated by UZGA. The maiden flight was an important accomplishment for the project, as it was the first time the aircraft was operated exclusively with Russian-developed propulsion hardware.
Engineers have systematically expanded the test program and amassed a vast amount of structural and performance data since that time. Additionally, the aircraft is equipped with advanced onboard measurement equipment that captures hundreds of flight parameters during each sortie. These measurements are indispensable for verifying aircraft behavior during the certification process and guaranteeing adherence to Russian aviation safety regulations.
Endurance Testing Pushes the Engine to Its Limits
Shortly before Innoprom-2026, the VK-800SM engine underwent a rigorous 150-hour endurance testing program in conjunction with flight tests. The engine is continuously operated at maximum power settings during these extended bench tests to exhibit thermal stability, durability, and reliability in the most demanding operating conditions.
These endurance campaigns are a critical component of engine certification, as they confirm that critical components—such as turbine blades, bearings, fuel systems, and control mechanisms—can endure extended operation without experiencing unacceptable wear or failure.
The successful completion of these tests will eliminate one of the most significant hurdles to obtaining certification for the engine, which is a prerequisite for the certification of the entire aircraft.
Measuring Real-World Aerodynamic Loads
The engine’s piping system and the AV-901 turbine blades are currently undergoing strain-gauge testing, which is one of the more technically challenging stages.
Deformation sensors have been installed across the engine’s pipelines by engineers to quantify the vibration stresses that are produced during operation. The data helps ascertain whether the piping system can withstand long-term exposure to engine-induced vibrations without fatigue cracking or structural failure.
Strain gauges have been installed on the propeller blades to monitor the aerodynamic loads that are generated as airflow flows to the aircraft’s nose and fuselage before reaching the propeller. These complex airflow interactions cannot be accurately reproduced in laboratory conditions, making real-flight measurements indispensable.
The data that is generated will be used to improve structural models, verify engineering calculations, and verify that the propeller and engine are operating safely throughout the aircraft’s flight envelope.
A Critical Step in the Rebirth of Regional Aviation
Officials now believe that the Baikal program has entered its decisive phase, although it has undergone many schedule revisions since development commenced in 2019. The Russian authorities stated that the early selection of the domestic VK-800SM engine during the certification process prevented further delays in the program that would have resulted from the need to repeat certain parts of the certification campaign.
The LMS-901 Baikal, Russia’s first modern, domestically powered light utility aircraft designed for widespread regional operations, could be operational by 2027 if certification proceeds in accordance with the current timetable. The successful certification of a new aircraft would not only introduce a new aircraft to a country that heavily relies on aviation to connect thousands of remote settlements, but it would also represent a significant milestone in the reconstruction of an independent regional aviation capability based on 100% Russian-designed technologies.
