486-341 - Piper Aircraft OEM Cable Fairlead Segment

486-341 – Piper Aircraft Cable Fairlead Segment

Available now on the Airparts.aero Marketplace.

The Piper Aircraft 486-341 is a genuine OEM, flight-critical fairlead segment. This component is specifically designed to guide aircraft control cables safely through airframe structures, such as bulkheads or ribs. Its primary, indispensable function is to prevent the control cable from chafing or rubbing against the structure, which would lead to dangerous cable fraying, wear, and potential failure. It provides a smooth, low-friction surface for the cable to pass over or through, ensuring the integrity and smooth operation of the flight control system.

Manufactured by Piper Aircraft to their exacting specifications, this fairlead segment is typically molded or machined from a durable, low-friction polymer, often a phenolic resin composite or a high-grade nylon material. This material selection is critical, providing excellent wear resistance against the steel cable while being lightweight and resistant to environmental factors. Maintaining the condition and proper installation of these fairleads is essential for the longevity and safety of the aircraft's control cables.

Key Features

• Genuine Piper Aircraft OEM Part: Guarantees the correct material, precise dimensions, and groove profile for the specified control cable size.

• Prevents Control Cable Chafing: Provides a critical barrier between the moving control cable and the stationary airframe structure, eliminating wear and friction.

• Low-Friction Material: Typically made from phenolic or nylon, offering a smooth, self-lubricating surface for the cable to slide against, minimizing control system friction.

• Reduces Risk of Cable Failure: Protects control cables from abrasion and fraying, which can severely compromise their strength and lead to failure.

• Maintains Smooth Control Operation: Contributes to a smooth, low-resistance feel in the flight controls by minimizing cable drag.

• PA-44 Series: Seminole

• PA-46 Series: Malibu, Mirage, Meridian, M-Class

Crucial Note: The specific aircraft model, serial number, and location (e.g., bulkhead pass-through, rib guide) must be checked against the latest revision of the official Piper Aircraft Illustrated Parts Catalog (IPC) to ensure correct part number applicability.

Applications

The specific application for this fairlead segment must be confirmed via the IPC. Common uses include:

• Guiding aileron, elevator, rudder, or trim control cables through bulkheads, ribs, and other airframe structures.

• Preventing cable contact with structural edges or other components.

• Maintaining proper cable alignment and routing.

Why Choose 486-341?

Choosing the genuine Piper 486-341 fairlead segment is essential for ensuring the safety and longevity of your aircraft's flight control system. Control cables are flight-critical, and protecting them from abrasion is non-negotiable. Using a non-certified fairlead risks incorrect material (leading to rapid wear of the fairlead or, worse, the cable), improper fit (allowing the cable to jump out or still contact structure), or inadequate durability. A worn or missing fairlead will inevitably lead to cable damage and a potential loss of control. The genuine Piper OEM part guarantees the certified quality, precise fit, and correct low-friction material required for this critical application.

The 486-341 fairlead functions based on fundamental tribological principles – the science of friction, wear, and lubrication. Its primary role is to manage the interaction between the moving steel control cable and the stationary airframe. The material, likely a phenolic composite or Nylon (Polyamide), is chosen for its low coefficient of friction when in sliding contact with steel. This minimizes the energy loss (drag) within the control system and reduces the rate of wear on both the cable and the fairlead itself. Furthermore, these materials possess good abrasion resistance and are relatively self-lubricating, meaning they maintain low friction even without external lubricants. Critically, the fairlead prevents fretting fatigue on the cable. Fretting occurs when two surfaces in tight contact experience minute relative motion (like a cable vibrating against a structural edge). This micromotion causes localized wear, surface oxidation, and initiates microscopic fatigue cracks, which can significantly reduce the cable's fatigue life and lead to unexpected failure. The fairlead provides a smooth, conforming, low-friction path that eliminates this damaging contact.

Note: This is a flight-critical component. Fairleads are subject to wear and should be inspected at every annual/100-hour inspection for excessive groove wear, cracking, security of attachment, and proper cable alignment. A worn or damaged fairlead that allows cable-to-structure contact is unairworthy and MUST be replaced immediately. Ensure correct orientation and secure installation per the maintenance manual.
