62371-008 – Piper Aircraft Aileron Hinge Assembly
Available now on the Airparts.aero Marketplace.
The Piper Aircraft 62371-008 is a genuine OEM, flight-critical aileron hinge assembly. This precision-engineered component serves as the primary structural pivot point connecting the aileron flight control surface to the aircraft's wing structure. Its indispensable function is to allow for the smooth, low-friction rotation of the aileron, enabling the pilot to control the aircraft in roll. This hinge must accurately transmit control inputs while bearing significant aerodynamic loads under all flight conditions.
Manufactured by Piper Aircraft to their exacting specifications, this assembly is typically fabricated from high-strength, forged or machined aluminum alloy for an optimal strength-to-weight ratio. It is designed to provide a secure attachment point and incorporates a bearing or bushing interface to ensure smooth articulation with minimal free play. The integrity and precise function of the aileron hinges are absolutely paramount for maintaining aircraft controllability and preventing potentially catastrophic phenomena like control surface flutter.
Key Features
Genuine Piper Aircraft OEM Part: Guarantees the correct material strength, precise dimensions, bearing/bushing specifications, and corrosion protection as designed by the manufacturer.
Provides Aileron Articulation: Serves as the critical pivot point allowing the aileron to deflect up and down for roll control.
High-Strength Aluminum Alloy Construction: Typically forged or machined from aerospace-grade aluminum (e.g., 2024-T351, 7075-T651) for maximum strength, durability, and fatigue resistance with minimum weight.
Low-Friction Pivot: Incorporates a precision bearing or bushing to ensure smooth aileron movement with minimal control force required from the pilot.
Corrosion-Resistant Finish: Treated with anodizing or chemical conversion coating and primer to protect against environmental degradation.
Flight-Critical Component: A primary structural element within the flight control system linkage.

Why Choose 62371-008?
Choosing the genuine Piper 62371-008 hinge assembly is an absolute necessity for flight safety. The ailerons are primary flight controls, and the integrity of their attachment points is non-negotiable. A worn or failed hinge can lead to control surface binding, excessive free play (which degrades control response and increases susceptibility to flutter), or even the catastrophic separation of the control surface. Using a non-genuine part risks incorrect material strength, improper fit leading to stress concentrations, or inadequate corrosion protection. The genuine Piper OEM part is the only way to guarantee the certified quality, precise fit, and reliable performance required for this flight-critical application.
The 62371-008 hinge assembly functions as a revolute joint, constraining motion to pure rotation about a single axis defined by the hinge pin or bolt. From a structural standpoint, it must safely transmit aerodynamic loads from the aileron into the wing structure. These loads include lift forces, drag forces, and potentially significant inertial loads during maneuvers. The hinge fittings are therefore subject to complex shear and bearing stresses. The material, typically a high-strength aluminum alloy like 7075-T651, is chosen for its high yield strength and excellent fatigue resistance to withstand these cyclic loads without failure over the aircraft's lifetime. The incorporation of a bearing or bushing is critical for minimizing static and dynamic friction. Low friction ensures smooth control feel and reduces the likelihood of control system hysteresis (slop or deadband), which can negatively impact handling qualities and increase the risk of flutter—a dangerous aeroelastic instability.
Note: This is a flight-critical primary flight control component. It is subject to rigorous inspection at every annual/100-hour inspection for cracks, corrosion, wear, security of attachment, and freedom of movement. Worn bushings or bearings within the hinge must be replaced according to maintenance manual limits. Installation must be performed by a certified A&P mechanic in strict accordance with the Piper Maintenance Manual. Correct alignment and rigging after installation are essential.
