PD-8 Engine Thrust Issue Resolved; Certification Date Announced
Certification Timeline and Technical Developments
The certification of the latest PD-8 aircraft engine is now scheduled for April 2026, according to materials released by Rosaviatsia during the final board meeting of the Ministry of Transport of the Russian Federation. This engine is set to become the primary powerplant for the short-haul SJ-100 airliner and, in the longer term, for the Be-200 amphibious aircraft.
Originally, the PD-8 certification was planned for November 2025 but was subsequently postponed to the first quarter of 2026. The delay followed reports in December 2025 from a source within the aviation industry, cited by Business Online, indicating that the PD-8 engine was not producing the necessary thrust to support flights with a full passenger cabin. The thrust at maximum take-off mode for the PD-8 is rated at 8,056 kgf. Recent updates suggest that the thrust issue has now been resolved, allowing the certification process to proceed.
Manufacturing Innovations
Rostec has released unique footage showcasing the manufacturing process of PD-8 components for the SJ-100 aircraft. The video highlights the 3D printing of the oil sump, a critical element of the engine’s oil system, underscoring the advanced production techniques employed in the development of the PD-8 engine.
