Abstract: Disclosed is an arrangement in which the main landing gear assemblies of a large commercial airplane are each joined to the airplane at four attachement points. Two of the attachment points connect the landing gear side brace (12) and drag brace (14) to the airplane. The two remaining attachment points are aft (36) and forward trunnions (46) that are mounted to the airplane wing. The aft trunnion (36) pivotally connects one side of the landing gear shock strut (10) to the airplane and carries both vertical and torsional loading. The forward trunnion (46) is pivotally connected to the other side of the shock strut (10) by a trunnion link (44). An actuator (56) is coupled between the shock strut (10) and the trunnion link (44).
