0713624-2 – Textron Aviation Cessna OEM Brake Cylinder Anchor
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 0713624-2 is a flight-critical, OEM structural anchor for the brake master cylinder assembly on a wide range of Cessna Skyhawk and Skylane aircraft. This precision-machined component serves as the primary load-bearing interface between the brake cylinder and the airframe's rudder pedal support structure. When a pilot applies braking force to the top of the rudder pedal, the master cylinder is subjected to an equal and opposite reaction force. The 0713624-2 anchor is engineered to absorb this entire reaction force and transfer it safely into the primary airframe structure, preventing failure of the brake cylinder's mounting.
Fabricated from a high-strength, fatigue-resistant aluminum alloy, this component is designed to withstand thousands of high-load application cycles, from gentle taxiing to maximum-effort braking during a rejected takeoff. Its structural integrity is absolutely paramount for the reliability of the braking system. A failure of this seemingly simple part would result in the brake master cylinder detaching from its mount, leading to an immediate and total loss of braking capability on one side of the aircraft.
Key Features
OEM Certification: A genuine Textron Aviation (Cessna) part, guaranteeing the specified material strength, heat treatment, and dimensional accuracy required for this critical load path.
High-Strength Aluminum Construction: Machined from a solid billet of aerospace-grade aluminum alloy, providing exceptional strength and fatigue resistance.
Precision Machining: CNC-machined to exacting tolerances for a perfect fit, ensuring proper alignment of the brake cylinder and preventing stress concentrations.
Superior Corrosion Protection: Finished with a chemical conversion coating and a durable primer to prevent corrosion in the harsh cockpit and firewall-forward environment.
Flight-Critical Design: Engineered as a key structural link in the braking system, essential for pilot control and aircraft safety on the ground.

Why Choose 0713624-2?
The aircraft's braking system is a no-fail system. The 0713624-2 anchor is an engineered structural component whose performance is calculated and verified by the aircraft manufacturer. Using a non-certified or counterfeit part introduces an extreme risk of material or manufacturing deficiencies. An anchor made from an incorrect alloy or with improper heat treatment could fail catastrophically under a single, hard braking application, leading to a complete loss of braking on that wheel. This can easily result in a dangerous ground loop or runway excursion. Sourcing a genuine, traceable Textron Aviation part is the only way to ensure the safety and airworthiness of the aircraft's braking system.
The engineering design of the 0713624-2 anchor is a practical application of load path management. It is not merely a bracket, but a purpose-built structural link. Its geometry, hole locations, and material thickness are meticulously calculated using Finite Element Analysis (FEA) to create a predictable and robust load path. The forces generated during braking are channeled from the master cylinder through the body of the anchor and into the hardened steel attachment bolts. These forces are then resolved into shear and bearing stresses that are transferred into the reinforced structure of the rudder pedal support assembly. The design ensures that these significant, concentrated loads are distributed safely into the airframe without inducing damaging stresses in adjacent, non-structural components, thereby maintaining the long-term integrity of the entire cockpit floor and firewall structure.
Note: The 0713624-2 is a flight-critical structural component. Installation must be performed by a certified A&P mechanic. It is recommended to use new, specified mounting hardware upon installation. All fasteners must be torqued to the values specified in the Textron Aviation Maintenance Manual for the specific aircraft model. A full functional check of the braking system must be performed prior to returning the aircraft to service.
