Just about all propeller driven airplanes big and small have the engine thrust line canted down a couple degrees from the wing chord line (not necessarily the longitudinal axis - that depends on the wing incidence), roughly equal to the cruising AOA, so that the thrust line is aligned a little closer to the free stream at cruise. On the A400 it looks like the nacelles are creating a bit of an optical illusion that exaggerates the effect, although the propellers do appear to be canted a bit relative to the fuselage. Thrust lines may also be offset to mitigate undesired pitching moments caused by thrust.
Single engine airplanes with the engine on the nose also often cant the engine to the side several degrees as well, to compensate for P factor and torque effects, reducing the amount of fin offset required at the tail. Look straight down on a typical single like a 172, with the prop stopped horizontally, and you can see the prop isn't quite parallel to the wings. Once you gain awareness of this you start to notice that most single engine planes you see have engines that are cockeyed, as if they were bent.
