0500118-127 – Textron Aviation OEM Right Side Brake Line Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 0500118-127 is an OEM, flight-critical flexible brake line assembly designed for the right-hand main landing gear of specific Cessna high-performance single-engine aircraft. As the counterpart to the left-side assembly, this line provides the essential high-pressure hydraulic connection from the aircraft's rigid plumbing to the brake caliper on the articulating landing gear strut. It is meticulously engineered to endure the severe dynamic environment of ground operations, including constant flexing, high-frequency vibration, and significant hydraulic pressure fluctuations.
The assembly features a robust multi-layer construction, comprising a specialized inner core compatible with aviation hydraulic fluids, which is protected and reinforced by a braided corrosion-resistant steel (CRES) outer sheath. This design ensures exceptional burst strength and resistance to chafing. The assembly is completed with factory-installed, precision-manufactured fittings and pre-bent rigid tube sections, which guarantee a leak-free, perfect-fit installation. The reliability of the 0500118-127 brake line is fundamental to the safe ground handling of the aircraft, directly impacting braking performance and directional control.
Key Features
OEM Certification: A genuine Textron Aviation part, ensuring 100% compliance with original design specifications for material, fit, and performance.
High-Pressure Performance: Engineered to safely manage the high operating pressures and dynamic spikes of the aircraft's hydraulic braking system.
Hybrid Flexible/Rigid Design: Combines a flexible hose section to accommodate landing gear travel with rigid, pre-formed tubing for precise routing and structural integrity.
CRES Reinforcement: The braided stainless steel outer layer prevents hose expansion under pressure for a firm brake feel and provides superior protection against abrasion.

Aircraft Brake System Integration: Serves as a vital link in the independent right-side hydraulic brake circuit, enabling differential braking for steering.
Why Choose 0500118-127?
There is no room for compromise in an aircraft's braking system. The OEM 0500118-127 assembly is engineered and tested to withstand thousands of pressure cycles and extreme operational stresses. The use of uncertified, substitute, or counterfeit parts introduces a severe risk of hose rupture or fitting failure, which could lead to a sudden loss of braking on the right side. Such a failure could result in a loss of directional control, a ground loop, or a runway excursion. Sourcing a genuine Textron Aviation part from an authorized distributor is the only way to guarantee the safety, compliance, and performance intended by the aircraft manufacturer.
The braided corrosion-resistant steel (CRES) sheath on the 0500118-127 assembly serves a critical function rooted in the physics of fluid dynamics. Per Pascal's Principle, hydraulic pressure is transmitted equally throughout a closed system. The CRES braid acts as a reinforcement with high hoop strength, effectively preventing the elastomeric inner hose from expanding radially under this pressure. Without this reinforcement, the hose would swell, causing a volumetric change in the system. This expansion would dissipate energy and require greater fluid displacement to actuate the brake caliper, resulting in a delayed and "spongy" response at the pedal. By maintaining a near-constant volume, the CRES braid ensures the instantaneous transmission of force, providing the pilot with a firm, immediate, and predictable braking action essential for precise ground control.
Note: The 0500118-127 is a flight-critical safety component. Installation must be performed by a certified A&P mechanic in strict accordance with the current Textron Aviation maintenance manual for the specific aircraft model. All fittings must be torqued to specified values, and the brake system must be meticulously bled of air and leak-checked before the aircraft is returned to service. Brake hoses are condition and/or life-limited items and must be inspected and replaced as mandated by the maintenance schedule.
