Ural Civil Aviation Plant (UZGA) has conducted the first flight of the third flying prototype of the LMS-901 Baikal light utility aircraft. Aircraft No. 535 (serial No. 0005) departed from the company’s airfield on Feb. 23.
The aircraft is powered by the Russian-built VK-800SP turboprop engine paired with the AV-901 propeller. Prior to flight, the prototype completed a full ground test campaign covering major systems and assemblies. The crew performed a single traffic pattern and executed a normal landing. The flight lasted 10 minutes at an altitude of approximately 1,000 ft and a speed of 118 mph.
According to UZGA Chief Designer Alexander Silin, engineers introduced several design refinements following tests of the second prototype. The team adjusted the wing incidence angle, upgraded the main landing gear, and redesigned the forward fuselage section. Engineers also updated onboard systems, including engine accessories, the fuel system, and flight control systems.
The aircraft will now undergo ground testing of the onboard wiring network, including certification-related checks and ground vibration/frequency tests. UZGA plans to proceed to preliminary and certification flight testing afterward.
On Dec. 24, 2025, UZGA began joint flight tests of the VK-800 engine and AV-901 propeller installed on the second flying prototype (Aircraft No. 532).
The third prototype features a revised configuration compared with earlier aircraft. Engineers redesigned the cockpit forward section to improve ergonomics and enhance crashworthiness. The company also upgraded the main landing gear. The revised wing incidence aims to eliminate the tendency for premature liftoff during takeoff in gusty wind conditions.
The LMS-901 is designed to carry up to nine passengers or up to 3,300 lb of payload. UZGA lists a maximum range of approximately 930 miles and a cruise speed of up to 155 mph. The aircraft targets regional and remote operations, including service on local routes and special-mission work in areas with limited airport infrastructure.
