8. Main Gear Reaction Link
A. The main gear reaction link forms the upper member of a space frame, consisting of the shock strut, the side strut, and the reaction link (Fig. 1). Most of the side loads acting on landing gear are transferred through the reaction link to the upper end of the shock strut. The outboard end of the reaction link is attached through a universal joint to the trunnion link connection. The inboard end is attached to structure at the main gear uplock brackets. All the landing gear lock actuating mechanism is mounted on the reaction link.
9. Static Ground Assembly
A. The static ground assembly is attached to the main gear at the lower torsion link attachment to discharge static electricity to ground upon contact. The ground strap support bracket is attached to the shock strut by the torsion link lower antirotation bolt. The ground wire is attached to the support bracket with fasteners to allow vertical adjustment so that the ground wire will make contact with the ground.
