The Russian Ministry of Industry and Trade has signed a contract worth 2 ₽ billion with Yakovlev, a subsidiary of the United Aircraft Corporation. The funds are designated for research and development to replace existing engines on SSJ-100 aircraft with domestic PD-8 power plants.
The project spans from 2026 to 2028 and covers three specific aircraft versions: RRJ-95B, RRJ-95B-100, and RRJ-95LR-100. The scope includes design, experimental, and certification work, as well as flight testing. The final output will be a service bulletin detailing the engine replacement process.
The contract was finalized in October 2026, with a completion deadline set for December 20, 2028. According to UAC head Vadim Badekha, between 50 and 100 aircraft may require this engine upgrade. Currently, Rosaviatsia reports that 154 SSJ-100 units are in operation across Russia.
In parallel, the United Engine Corporation is exploring options to extend the service life of the current SaM146 engines for a portion of the fleet. The SSJ-100 program aims to replace approximately 40 imported systems with domestic components, including avionics, landing gear, and control systems.
