Yes that is one engine. Were dose it say it for example a io520 ?
Gibberish or dont you understand whats happening with the engine chamber ?
Btw the engine manufacture holds the type cert for the engine however the airframe manufacture takes control of the engine when fitted into their airframe and as such their data for the engine takes precedence over the engine manufacture.
