AE3664056B0060 – Textron Aviation OEM Brake Hose Assembly

Available now on the Airparts.aero Marketplace.

Overview

The AE3664056B0060 is a genuine OEM, high-pressure Teflon brake hose assembly, engineered in strict accordance with the SAE Aerospace Standard AS3664. This flight-critical component is specified by Textron Aviation for use in the demanding hydraulic brake systems of high-performance aircraft. The assembly features a conductive Polytetrafluoroethylene (PTFE) inner tube, reinforced with a high-strength stainless steel braid, and protected by an integral outer chafe guard. Designed to handle operating pressures up to 3000 PSI, this hose provides the flexible connection between the rigid brake lines on the landing gear strut and the brake caliper on the wheel, ensuring reliable braking performance.

Key Features

• 3000 PSI High-Pressure Rating: Specifically designed and tested for high-pressure hydraulic systems, making it the standard for aircraft brake lines and other demanding fluid power applications.
• Conductive PTFE Inner Tube: The seamless, smoothbore inner tube is made from carbon-impregnated PTFE (Teflon). This construction is chemically inert to all aviation hydraulic fluids (including Skydrol) and dissipates static electricity generated by fluid flow, preventing electrostatic discharge.
• Corrosion-Resistant Steel Braid: A single braid of high-tensile, 300-series Corrosion Resistant Steel (CRES) wire provides the strength to contain high pressures and offers a high degree of protection against impacts and damage.
• Integrated Chafe Guard: Features an integral outer cover made of a durable elastomer like silicone. This provides an essential layer of abrasion resistance, protecting the steel braid from chafing against other landing gear components during gear retraction, extension, and ground operations.
• OEM Specification: As a component specified by Textron Aviation, it guarantees the correct length, end fitting type and orientation, and pressure rating required for a specific application on their certified aircraft, ensuring an airworthy and reliable installation.

Aircraft Compatibility

Hose assemblies conforming to the high-pressure AE3664 standard are used extensively on modern business jets, turboprops, and other high-performance aircraft.

• Common Aircraft Platforms:
  • Textron Aviation: Cessna Citation series, Beechcraft King Air series, and other platforms requiring 3000 PSI hydraulic hoses.
• Common System Applications:
  • Brake Systems: The primary application is as the flexible hose connecting the rigid airframe brake lines to the wheel brake caliper.
  • High-Pressure Hydraulic Systems: Used for landing gear actuators, flaps, spoilers, and thrust reverser systems.

Applications

The AE3664056B0060 is the engineered solution for critical, high-pressure flexible connections:

• Brake Line Articulation: Provides the necessary flexibility to allow for the full range of motion of the landing gear during retraction, extension, and steering without stressing the fluid lines.
• Vibration Isolation: The flexible design absorbs the intense vibration and shock loads experienced by the landing gear, preventing the fatigue failure that would occur in rigid tubing.

Why Choose AE3664056B0060?

A failure of a brake hose during landing or taxiing can lead to a complete loss of braking on one side, resulting in a serious directional control problem. The AE3664056B0060 hose assembly is engineered for maximum reliability to prevent such failures. Its multi-layer, high-pressure design is far superior to standard industrial hoses. Using a genuine OEM-specified hose guarantees that the length and fitting orientation are perfect for the intended installation, preventing chafing and stress that could lead to a rupture. For the flight-critical brake system, there is no substitute for certified, high-pressure hose assemblies.

The construction of the AE3664056B0060 assembly is a testament to aerospace fluid power engineering. The smoothbore PTFE inner tube has a near-zero coefficient of friction, ensuring efficient hydraulic power transmission with minimal pressure loss. It is also non-aging and unaffected by hydraulic fluid, unlike rubber which can degrade over time. The CRES braid is woven at a specific angle to provide maximum strength against hoop stress (the outward force from internal pressure) while still allowing the hose to be flexible. The permanently swaged or crimped end fittings create a metal-to-metal seal with the braid, providing a connection that is stronger than the hose itself and guarantees a leak-proof, high-reliability assembly.

Note: This is a flight-critical component. Installation must be performed by a certified A&P mechanic. The hose must be routed in accordance with the aircraft maintenance manual, ensuring it is properly supported with clamps and is not subject to twisting, chafing, or bending tighter than its specified minimum bend radius. The end fittings must be torqued to the correct value.
