In the same year, the chief designer of the project, Sergei Merenkov, confirmed that the L-610 was only an inspiration of the TVRS, and two planes will be completely different.

[2] On December 25, 2020, a State contract was signed between the Ministry of Industry and Trade of Russia and UZGA.

[2] Cooperation for the production of elements and aggregates includes cities such as Taganrog, Komsomolsk-on-Amur, Nizhny Novgorod, Samara[2] and Smolensk.

In April 2022, TsAGI specialists, commissioned by UZGA, summed up the interim results of tests of the TVRS-44 aircraft in the wind tunnel in terms of aerodynamic characteristics.

[5] To reduce design time, a number of Russian-made parts and aggregates were used from other serially produced and in production aircraft: cockpit canopy and conical windshields (from An-74 and An-140), main landing gear (from An-72/An-74), front strut (from Su-80GP).

[2] In January 2023, it became known that on the basis of the Dubna complex at TsAGI, a series of emergency splashdown tests and a series of ejection tests of a dynamically similar model of the Ladoga aircraft were completed, which consisted of more than 100 launches with different initial parameters.

Also, parts of the passenger compartment will be made from composite materials: cabin floors, overhead luggage racks and interior lining.

[2] In July 2021, it became known that the St. Petersburg enterprise ODK-Klimov received technical specifications for the creation of a power unit (PS) for the TVRS-44 based on the TV7-117ST-01 engines, previously developed for the Il-114-300 aircraft.

A number of other smaller design changes were also introduced to make fuel consumption more economical than the base engine.
