Let me get this straight.
You are an MRO. You remove an engine from an a/c.
You remove the QEC kit from said engine.
Another MRO fits an engine to another a/c (owned by the same operator)
You want to make that QEC kit available to the other MRO?
What is fitted to the a/c that had the engine change? Is that a complete powerplant? Or are we on a merry go round with QEC kits rotating through various MROs?
Just curious because in my (admittedly, limited) experience, when one changes an engine it's just a case of a quick swap of components (QEC kit) from the u/s engine to the new servicable one.
