PD-35 could force a major Il-96 redesign

Russia’s PD-35 engine may demand far more than a simple engine swap for the Il-96. According to aviation expert Roman Gusarov, fitting the aircraft with the planned powerplant would likely require a substantial redesign of the jet itself, including a new wing, landing gear, and parts of its onboard systems.
The core issue is the gap in class and size. The Il-96 was originally designed around four relatively compact engines, while the PD-35 is intended to be a much larger and heavier unit. That changes more than the pylons: it affects the wing’s structural load path and would also require landing gear capable of handling different weight and operating conditions.
Gusarov said it is too early to talk about a ready modernization program because the engine has not yet reached the operational stage. If the PD-35 eventually enters series production, the industry would then face a broader economic choice: deeply rework the Il-96 or build a new platform around the more powerful engine. In practical terms, the new engine could end up requiring something close to a new aircraft.
The backdrop matters. The Il-96 has long ceased to be a mass-market passenger jet and now exists more as a limited-production aircraft for a narrow set of tasks. Serial production in Voronezh remains small, and even at current rates the plant can produce only about two aircraft per year. The factory is also occupied not just with final assembly, but with manufacturing parts for other programs including the Superjet and MC-21.
That makes the PD-35 question especially significant. In the widebody market, Boeing and Airbus have dominated for years, and new projects in this segment often rise or fall on the engine. Without a finished and efficient powerplant, an aircraft tends to remain on paper or in the experimental stage. For now, the Il-96 looks less like an immediate re-engining candidate and more like a backup platform waiting on whether the PD-35 ever makes it to series production.
