Bell 407 RESTART FAULT question…
The Bell 407 RFM states that for a FADEC RESTART FAULT : When throttle is repositioned to idle stop (during engine shutdown) the PMA will go offline and engine may flameout. The PMA goes offline when the NP goes below 85% but the FADEC should still be supplied by DC battery/gen power. So my question is why would the engine flameout at idle with a RESTART FAULT? Thank you for any insight!
