That explains it. If a loss of airframe power triggers a RESTART FAULT light, then the 'Note" makes perfect sense. There are other faults that may trigger the light but the note would seem prudent if loss of airframe power is one of them.
If I’m understanding correctly your saying the RESTART FAULT “could be” triggered because of a loss of power to the FADEC therefor taking away the PMA it would have no power and the engine would flame out. Correct?
