Thank you Safety Concerns; What's the source please? (read back through the last five pages thinking I'd missed it, that's all).
That's pretty big news - means no flame-out, just the inability to develop sufficient thrust to remain aloft.
Typical wording from a flight safety department advising their users.
I don't believe that you can interpret a flame out or not from the wording, but only that there was enough RPM to drive the aircraft power.
To assess flameout you need EGT.
