Just noticed these pictures in the db. There is a section of fuselage abeam the prop blade which is painted white, while the rest of it is greenish primer (except, presumably, composite parts). The picture on the right seems to show a raised area on the fuselage at the same place, however that is painted the same primer as the rest. My questions :

- Does that area have additional strengthening to protect the passengers in the event of a blade-out?
- Why have they been painted white in one case, and primer in another?

Thanks in advance

Yes, there is a strengthening there.
Not specifically for catastrophic propeller failure case, as I feel that would have to take a bit more to protect the cabin (although every mm helps, naturally), but propeller can shed and throw all kinds of things at the area, ice, for one, or pieces of anything that got into propeller disc from birds to debris from the runway on reverse thrust.

It's mainly for when the prop starts shedding ice in icing conditions. The chunks can be pretty big. On the Dash 8, this shield is made out of kevlar. One interesting note on the power of these ice chunks: for some reason, the engineers at Bombardier decided to put a Comm antenna right in the line of fire. We have had plenty of planes come in with this antenna missing from getting knocked off by ice.
