65003-030 – Piper Aircraft Landing Gear Bushing
Available now on the Airparts.aero Marketplace.
The Piper Aircraft 65003-030 is a genuine OEM, flight-critical sleeve bushing, also known as a plain bearing. This precision-machined component is specifically designed for use within the landing gear assemblies, likely at pivot points in the retract mechanism or torque links, on various Piper aircraft. Its primary function is to provide a low-friction, replaceable wear surface, protecting the more expensive or structurally integral surrounding components from wear, elongation, and damage. This ensures the longevity, smooth operation, and precise alignment of the landing gear system.
Fabricated from a high-quality bearing material, likely a bearing bronze alloy (such as SAE 660 / CDA 932) specified by Piper for its excellent load-carrying capacity and wear resistance, this bushing is engineered for durability in the high-load, high-cycle environment of the landing gear. It is designed to be installed with a precise fit into its housing, providing a dimensionally stable bore for the connecting bolts or pins. Maintaining the tight tolerances within the landing gear mechanism is crucial for preventing shimmy, ensuring positive locking, and guaranteeing safe and reliable operation.
Key Features
Genuine Piper Aircraft OEM Part: Guarantees the precise dimensions, correct bearing alloy material, and quality standards specified for the landing gear system.
Provides Replaceable Wear Surface: Acts as a sacrificial element in articulating joints, protecting primary structural components like torque links and brace arms from wear and elongation.
Low-Friction Bearing Material: Typically manufactured from a high-quality bearing bronze alloy, selected for its excellent lubricity, load capacity, and anti-galling properties when paired with steel pins or bolts.
Precision Machined Tolerances: Ensures accurate inner and outer diameters for proper installation fit (press-fit or slip-fit as required) and correct running clearance with the mating fastener.
Maintains Landing Gear Integrity: Prevents excessive free play ("slop") from developing in critical pivot points due to wear, which is essential for preventing shimmy and ensuring positive gear operation.

Why Choose 65003-030?
Choosing the genuine Piper 65003-030 bushing is essential for ensuring the safe and reliable operation of the landing gear system. Worn bushings in landing gear linkages are a primary cause of shimmy, excessive free play, and potential binding or failure of the mechanism. The OEM part guarantees the correct high-strength bearing material and the precise dimensional tolerances required for a proper fit. Using a non-certified bushing risks premature wear, incorrect clearances leading to unsafe conditions, or improper fit causing damage during installation or operation.
The 65003-030 operates under principles of tribology as a plain bearing, designed to function primarily in the boundary lubrication regime within the landing gear linkage. The specified bearing material, likely a leaded tin bronze such as SAE 660 (CDA 932), is engineered for this role. The copper matrix provides strength, while tin adds hardness. The crucial lead particles dispersed within act as a solid lubricant, smearing across the surface under load to prevent galling (adhesive wear) between the bushing and the steel pivot pin, especially during the high-load, low-speed articulation experienced during gear cycling. The inherent porosity of the bronze also retains grease applied during maintenance, providing a lubricant reservoir. The interference fit during installation is vital; it secures the bushing, preventing rotation within its housing and minimizing fretting corrosion, ensuring the long-term integrity of the landing gear geometry.
Note: This is a flight-critical landing gear component. Bushings are wear items and are typically replaced during landing gear overhaul or when wear exceeds limits specified in the maintenance manual. Installation usually requires specialized tooling (e.g., an arbor press with appropriately sized installation mandrels) to ensure the bushing is pressed in straight and without damage. The housing bore must be precisely measured. After installation, the inner diameter of the bushing MUST be reamed or honed to achieve the final, precise running clearance for the mating pivot pin as specified by Piper. Consult the applicable maintenance manual for lubrication requirements.
