AdAstraPerAspera,
The first SAS Dash with the MLG failure didn't feather or shut down the engine on the affected side. The second (and now third
) shutdown/feathered the engine on the affected side, it is now a talking point in the event of gear issues. The way a composite prop disintergrates is different from older metal blades which tend to deform instead of shatter on impact with the ground. There are situations where a precautionary engine shutdown may not be felt to be the best idea eg Severe icing conditions/turbulence or just low passenger numbers where people can be moved into areas clear of the prop arcs.
