    The plane belongs to Volga-Dnepr

    It can be repaired and returned to service.

    And it caused that kind of damage?

    Normally modern engines must ensure that they can safely shot down, even with a large bird ingestion...

    Possibly the D18T was not designed to ensure this.

    The pictures above do not correspond to the engine or plane in this case

    That's the case and this example proves it.

    Russia should get cracking on the PD-35. Most of the work has been done already getting the PD-14 into production.

    The D18T is a 23 ton max takeoff thrust engine so they will need a down scaled PD-35. But I have not heard of any
    such thrust range option in the PD series. Maybe it is easier to upscale the PD-14.

    Yes, it looks like it. But the problem is the D18T is old and tired. It was made by Motor Sich so we are looking at excessively
    long operational times. I doubt that these engines are less than 30 years old. They need to be retired ASAP.

    Yes there were both the PD24 and PD28 among the planned engines, but it is not clear by when.

    How I (and other people) posted in other threads, there is also the possibility of the NK23D, a high bypass derivative (with around 23 tons of thrust at max takeoff) of the NK32 (the engine of the Tu-160). Apparently an engine for the subsonic Pak-Da is being currently developed (also derived from the NK32). That could also be used as basis for the creation of a transport aircraft engine.

    I don't know if it may affected this engine in particular, but I read not long ago about Motor Sich having reliability problems with the D18T. Russia in principle has already the capability to repair the engine, that is not as good as building complete engines and being able to substitute them but they will have to live with it for the time being.

    Volga Dnepr has grounded the entire fleet until the engines are cleared by the manufacturer. With the situation between Russia and Ukraine is this even possible? I think this will pressure a global grounding of the fleet. Does any maint for the engines on the RUF or VD planes get done in Ukraine?
