MC0713070-28 - McFarlane Aviation FAA-PMA Parking Brake Cable Assembly Replaces Textron 0713070-28

MC0713070-28 – McFarlane FAA-PMA Parking Brake Cable Assembly (Replaces Textron 0713070-28)

Available now on the Airparts.aero Marketplace.

The MC0713070-28 is a premium, FAA-PMA certified parking brake cable assembly from McFarlane Aviation, engineered as a direct, improved replacement for the Textron (Cessna) OEM part number 0713070-28. As a leader in the PMA market for control cables, McFarlane has incorporated several design enhancements to increase the service life, improve the operational feel, and enhance the corrosion resistance of this critical component. This assembly provides the essential mechanical linkage between the parking brake handle in the cockpit and the aircraft's parking brake valve or master cylinders.

This is not just a replacement part; it is an upgrade. McFarlane has specifically addressed the common failure modes of the original cable, such as internal corrosion, freezing, and stiff operation, by utilizing superior materials and sealing. The result is a more reliable and durable cable that ensures the parking brake can be set and, more importantly, released, every time.

Key Features

• FAA-PMA Approved Replacement: Fully certified by the FAA as a safe, airworthy, and direct replacement for Textron P/N 0713070-28.

• Made by Control Cable Specialists: Manufactured by McFarlane Aviation, a company renowned for its expertise and quality improvements in aircraft control cables.

• Improved Low-Friction PTFE Liner: Features a proprietary, high-lubricity Polytetrafluoroethylene (PTFE) liner, which ensures smooth, low-effort operation and prevents galling and binding of the inner cable.

• Superior Corrosion and Moisture Sealing: The conduit and end fittings are engineered with enhanced seals to keep out moisture and contaminants, the primary cause of internal corrosion and freezing.

• Heavy-Duty Stainless Steel Inner Wire: The inner control wire is made from a corrosion-resistant stainless steel for maximum strength and longevity.

Why Choose MC0713070-28?

Choosing the McFarlane MC0713070-28 is a decision for enhanced reliability and longevity. A sticky or frozen parking brake is not just an inconvenience; it can lead to a delayed departure, an inability to secure the aircraft on a ramp, or, in a worst-case scenario, a locked brake on takeoff or landing. McFarlane's design directly addresses these issues with a superior PTFE liner and improved environmental sealing. As a certified FAA-PMA part, it provides a safe and airworthy upgrade over the original design, often at a more competitive price point.

The superior operational feel and efficiency of the MC0713070-28 cable is a function of advanced tribology. The primary source of resistance in a push-pull control cable is the friction between the inner wire and the outer conduit liner. The McFarlane design utilizes a proprietary PTFE (Polytetrafluoroethylene) liner. PTFE has one of the lowest coefficients of friction of any known solid material, a property derived from the low intermolecular forces (van der Waals forces) of its tightly-packed, helical fluorine atoms which form a non-reactive sheath around the carbon backbone. This "self-lubricating" characteristic minimizes the force lost to friction as the inner wire moves, especially when the cable is routed around bends. This reduction in friction results in a smoother, more responsive feel at the control handle, reduces the strain on the cable and its end fittings, and prevents the stick-slip ("stiction") phenomenon that plagues older, grease-packed conduits, especially at low temperatures.

Note: This is a primary ground control component. Proper installation, routing, and rigging are essential for correct parking brake function. Care must be taken not to kink the cable or exceed its minimum bend radius during installation, as this will cause binding. After installation, the entire brake system must be functionally tested to ensure it can be reliably set and, most importantly, fully released. All work should be performed by a certified A&P mechanic in accordance with the Textron/Cessna maintenance manual.
