So the engines (as I see it) WERE NOT at a governed, stabilized idle, even though the gages might have suggested that. They were trapped by their degraded steady-state line intersecting the accel schedule
So equal damage then? Wow and little fan damage evident.
So where's the damage? Low compressor or high compressor? and what is the EGT?
If the EGT is high than I agree it's damage, but if the EGT is low than it probably is a governed limit.
