Disclosed is a crash paddle for reinforcing a primary fuselage structure of an aircraft. The crash paddle may be used for connecting the floor to the primary fuselage structure. The crash paddle includes a beam with in particular an H-shaped cross-sectional geometry, butt straps being arranged at both ends of the beam for connecting the crash paddle. In the region of the ends of the beam, the beam respectively has a resting surface 13, 14, the geometrical shape of which substantially corresponds to a hollow cylinder halved in the longitudinal direction. Placed around both resting surfaces and the longitudinal sides of the beam, in a peripheral groove is at least one endless loop. The endless loops respectively comprise an arrangement of reinforcing fibers, which is formed by a plurality of reinforcing fibers, such as for example carbon fibers, running substantially parallel to the longitudinal axis of the beam. The presence of the endless loops allows the crash paddle to absorb safely the tensile forces that are generally relevant in critical flying situations. The beam can therefore be dimensioned lighter for the usually considerably smaller compressive and tensile loads that occur in normal flying operation, so that a considerable weight saving is obtained.
