Unless the engine has seized or the gearbox failed it will remain in an NTS condition until feathered. The NTS system is only temporary until the crew manually feather the prop. Although it is a "drag reduction system" there is still plenty of drag you would want to get rid of ASAP, so if no auto relight or air start possible then the crew will feather it soon rather than later. As for picture in 267, 2 blades are clearly bent, maybe that would indicate some rotation but as for spectulating, that is up to the crash pro's, not me
