1. An aircraft assembly comprising:
a wing component comprising a triangular arrangement consisting of three fastening locations arranged in a triangle and in a plane;
an engine mounting pylon component connected to the wing component by three tension fasteners, wherein each of the three tension fasteners is secured to the engine mounting pylon component, -passes through a different one of the three fastening locations and is secured to the wing component;
wherein the wing component comprises three first spherical surfaces positioned such that the three first spherical surfaces each have a center, each of the centers is at a different one of the three fastening locations, and each of the three tension fasteners extends through a different one of the first spherical surfaces;
wherein the engine mounting pylon component comprises three second spherical surfaces having equal and opposite curvature to the three first spherical surfaces, each of the three second spherical surfaces are in contact with a different one of the three first spherical surfaces and each of the three tension fasteners extends through a different one of the three second spherical surfaces, and
wherein the triangular arrangement provides the three fastening locations on the wing component for fastening the engine mounting pylon component to the wing component.
