A landing gear support assembly comprises a first support member, for example a gear rib, extending from the rear spar of an aircraft, and a pintle support assembly for holding a pintle on which a landing gear assembly may be supported. The pintle support assembly is distinct from the rear spar, and is arranged such that the longitudinal axis of a pintle is offset from the support member in a direction along the length of the rear spar. This arrangement may allow a stowed landing gear assembly to be wholly contained within the aircraft wing.

With a simple configuration, plastic deformation of contacts can be prevented while avoiding increase in size, and occurrence of failure in electrical connection due to dust can be well prevented. In an elastic beam-like member of a first-side contact extending like a cantilever in an insulating housing, a bent extending part which substantially increases the span length of the elastic beam-like member is formed to be bent to have a curved shape at a root part serving as a part coupled to a fixing base part. A through hole is formed in a region including at least part of the bent extending part to ensure flexibility while enhancing elasticity of the contact, thereby preventing permanent deformation of the contact. Meanwhile, dust which has entered the equipment is caused to fall through the through hole, thereby ensuring electrical conductivity well.
