PC12 design flaw

Here I am cleaning two weeks of turbine soot off the sides of the fuselage and tops of the wings at the root. Clearly they made a design flaw when they put the the engine in the nose with the exhaust stacks sticking out the sides. The entire plane gets quickly coated in carbon soot! They never think of the poor shmucks who gotta clean the damn thing.

Honda on the other hand got it right ! No soot anywhere near the fuse, tail out of the exhaust stream.
