2600101-9 – Textron Aviation OEM Line Assembly for Caravan Aircraft
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 2600101-9 is a flight-critical, OEM flexible line assembly specifically engineered for the propeller control system of the Cessna Caravan family of aircraft. This assembly functions as the primary hydraulic conduit, transmitting high-pressure engine oil from the propeller governor to the propeller hub. This controlled oil pressure is the motive force that actuates the propeller's pitch change mechanism, allowing the pilot to control engine RPM and blade angle for optimal performance across all phases of flight, from takeoff to reverse thrust operations.
Constructed as a sophisticated, multi-layered hose, the 2600101-9 is designed to operate reliably in the harsh, high-vibration environment of the firewall forward. It features a specialized synthetic rubber inner core, reinforced with a braided steel sheath for exceptional burst strength, and is covered by an integral firesleeve for thermal protection. The precision-engineered fittings at each end ensure a secure, leak-free connection between the governor and the propeller. The integrity of this line is paramount; a failure would result in a loss of propeller control, leading to a potentially catastrophic overspeed or underspeed condition.
Key Features
OEM Certification: Genuine Textron Aviation part, guaranteeing exact fit, form, and function for the Caravan's propeller system.
High-Pressure, High-Temperature Capability: Engineered to withstand the full operational pressure and temperature of the Pratt & Whitney PT6A engine oil system.
Integral Firesleeve: Features a built-in, fire-resistant sleeve compliant with AS1072 standards, providing critical protection from engine compartment fires.
Vibration Resistance: Designed and constructed to endure the high-frequency vibrations of a turboprop engine without fatigue failure.
Corrosion-Resistant Fittings: Equipped with factory-installed, high-quality steel fittings for a durable, leak-proof seal.
Flight-Critical Component: A non-negotiable component for propeller system reliability and overall flight safety.

Why Choose 2600101-9?
The propeller control line is one of the most critical hoses in a single-engine turboprop aircraft. The failure of this component would lead to an immediate and serious in-flight emergency. The OEM 2600101-9 assembly is rigorously designed and tested to withstand the extreme combination of pressure, temperature, and vibration unique to the PT6A engine installation on the Caravan. Using non-certified, locally fabricated hoses introduces an unacceptable risk of fitting failure, hose rupture, or fire vulnerability. Sourcing a genuine, traceable Textron Aviation part is the only way to ensure compliance with airworthiness standards and guarantee the safety and reliability of the aircraft's propeller system.
The engineering of the 2600101-9 line assembly is a multi-disciplinary solution to a complex problem. The hose operates as a critical component in a hydraulic control system, where fluid compressibility and hose volumetric expansion must be minimized for precise propeller response. The braided corrosion-resistant steel (CRES) reinforcement layer provides the necessary hoop strength to nearly eliminate radial expansion under pressure, ensuring instantaneous transmission of the governor's hydraulic commands. Furthermore, the integral AS1072 Type II firesleeve is not merely a covering but a life-saving safety system. Composed of braided fiberglass insulation coated with a self-extinguishing silicone rubber, it is designed to withstand a direct flame at 2000°F (1093°C) for a minimum of 15 minutes, as mandated by 14 CFR §33.17. This provides the flight crew with critical time to manage an engine fire emergency and secure the engine without a catastrophic breach of the pressurized oil line.
Note: The 2600101-9 is a flight-critical and life-limited component. Installation must be performed by a certified A&P/IA mechanic in strict accordance with the current Textron Aviation Model 208 Series Maintenance Manual. All fittings must be torqued to the specified values. Adherence to the hose's mandated replacement interval is essential for continued airworthiness.
