31747-000 – Piper Aircraft OEM Rod End Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Piper Aircraft 31747-000 is a genuine OEM, flight-critical rod end assembly, engineered for use in the primary flight control systems of a vast range of Piper aircraft. This component is specifically designed to serve as the articulating joint on the aileron push-pull tubes, connecting the control rods to the aileron bellcranks. It is a high-strength assembly featuring an integral spherical bearing, which allows for smooth, binding-free movement in multiple axes. As a genuine Piper factory part, it guarantees the precise tolerances, material strength, and quality control required for a component that directly translates pilot inputs into control surface deflection.
Key Features
- Primary Flight Control Component: A critical linkage in the aileron control system. The integrity and precision of this part are directly responsible for the positive feel and immediate response of the aircraft's roll control.
- Integral Spherical Bearing: Features a precision spherical bearing swaged directly into the rod end body. This bearing is designed to accommodate the complex, multi-axis changes in angle that occur as the control system moves through its full range of travel, preventing binding and ensuring smooth operation.
- High-Strength Steel Construction: The rod end body is forged or machined from a high-strength, heat-treated steel alloy, providing the tensile and compressive strength needed to handle flight control loads without deformation or failure.
- Corrosion-Resistant Plating: Plated with a durable cadmium finish to provide robust protection against corrosion, ensuring a long and reliable service life within the airframe structure.
- Genuine Piper OEM Part: As a genuine factory component, it guarantees conformance to the stringent material, dimensional, and performance standards of the original aircraft Type Certificate. This is the only way to ensure a safe and airworthy flight control system repair.

Applications
The 31747-000 is the specified component for flight control system maintenance and overhaul:
- Flight Control System Repair: Replaced to eliminate "slop" or "play" in the aileron system, which can result from a worn spherical bearing. This restores a crisp, positive control feel.
- Mandatory Inspection Item: Subject to rigorous inspection for any signs of corrosion, damage, or bearing wear (excessive radial play) during detailed airframe inspections.
- Restoration & Overhaul: An essential component to replace when performing a major restoration or overhauling the flight control system to ensure it is returned to factory-new tolerances.
Why Choose 31747-000?
The safety of flight is directly dependent on the integrity of the primary flight controls. A failure of a control rod end could result in a partial or total loss of aileron control. Using a genuine Piper 31747-000 OEM part is the only way to ensure the component has the certified material strength, proper heat treatment, and precision-manufactured spherical bearing required for this flight-critical application. There is no substitute for the quality and airworthiness assurance of a genuine OEM flight control component.

The spherical bearing within the 31747-000 rod end is a key engineering feature. A simple single-axis bearing or bushing would bind as the aileron bellcrank and push-pull tube move through their respective arcs. The spherical bearing, however, creates a ball-and-socket joint. This allows the bolt that passes through its center to pivot freely in a conical path, accommodating the constantly changing angles of the control linkage. This prevents bending stress (side-loading) on the rod end and its attaching bolt, ensuring the forces transmitted are purely axial (push-pull). This smooth, binding-free articulation is what allows for a sensitive and responsive feel at the pilot's controls.
Note: This is a flight-critical flight control system component. Installation must be performed by a certified A&P mechanic in strict accordance with the current Piper maintenance manual. All associated hardware should be carefully inspected and torqued to the specified value. A full flight control movement check must be performed after installation.
