The reason i bought it up is that significant damage can occur from what appears to be a benign stall.
I sure hope not.
A single "benign" stall due to aerodynamic effects like cross winds, inlet distortions, or even internal clearance and or compressor deteriorations should not damage the engine to the point where it affects continued safe flight and landing.
However many engine stalls are associated with already existing damage and therfore should be considered an indicator that's it time to minimize the effects.
The manuals should be clear about this
