The 587-368 is a Piper OEM aircraft spring used in various mechanical and control system assemblies within the aircraft. It functions as a tension or return-force component, providing controlled mechanical resistance, preload, or return action in systems where consistent spring force is required.

In Piper aircraft applications, springs of this type are commonly used in control mechanisms, cockpit controls, switch assemblies, latch systems, or linkage return systems, depending on aircraft model configuration. The exact installation location varies, but the function remains the same: to ensure proper mechanical positioning, return-to-neutral behavior, or controlled movement within an assembly.

This spring is manufactured to aviation standards from high-carbon spring steel or corrosion-resistant alloy steel, designed to maintain consistent elasticity over repeated load cycles. It is engineered to withstand vibration, temperature changes, and long-term cyclic stress typical in general aviation environments.

Because it is used in mechanical systems that affect operation or control feel, maintaining correct spring tension is important. Loss of elasticity, deformation, or corrosion can lead to improper system response or reduced functionality.
