Preloaded aircraft linkage assemblies with reduced noise during load reversal

A joint for a structure subjected to load reversal between a first structure and a second structure, the joint comprising:

• a first fitting fixed to the first structure;
• a second fitting fixed to the second structure;
• a link assembly pivotably coupled to the first fitting and to the second fitting, the link assembly having a free play clearance defined by a manufacturing of the joint and falling within a designed dimensional tolerance of the joint;
• a strap coupled to the link assembly at the first fitting and at the second fitting based on the free play clearance as defined by the manufacturing of the link assembly, the strap further configured to bias the link assembly to restrict movement of the link assembly within the free play clearance during load reversal in the joint;
• and
• wherein the strap is further configured to bias the link assembly to a limit of the free play clearance an operating state of an aircraft, wherein the first structure is a fuselage of the aircraft and the second structure is a wing of the aircraft.

A method of reducing noise in a joint during operation of an aircraft, the method comprising:

• installing a linkage assembly between a fuselage and a wing of the aircraft to support the wing;
• preloading the linkage assembly;
• determining a free play clearance in the linkage assembly due to manufacturing tolerance stacking;
• fabricating a strap based on the free play clearance;
• and
• installing the strap on the linkage assembly such that the strap biases the linkage assembly to restrict free play movement during pressurized flight of the aircraft.
