FE201-6-002 – Propeller Brake for ATR-72
Available now on the Airparts.aero Marketplace.
Overview
The FE201-6-002 is a genuine OEM, flight-critical propeller brake assembly, engineered specifically for the Pratt & Whitney Canada engine and propeller gearbox combination on the ATR 42 and ATR 72 series of regional airliners. This is not an in-flight system; it is a powerful, ground-operated hydraulic disc brake designed for two critical functions: to rapidly stop the propeller from windmilling after engine shutdown and to securely lock the propeller during "Hotel Mode" operations. Manufactured by industry leaders like Safran Electrical & Power to ATR's exact specifications, this assembly is fundamental to the safety of ground personnel and the efficiency of ground operations.
Key Features
- Hydraulic Disc Brake Mechanism: Employs a robust, hydraulically actuated caliper with high-friction brake pads. When activated, the caliper clamps down on a brake disc mounted to the propeller reduction gearbox, providing immense torque to quickly stop and hold the large-diameter propeller.
- "Hotel Mode" Operation Enablement: The primary safety device that allows the ATR to operate in "Hotel Mode," where the right-hand (#2) engine runs with the propeller locked. This enables the engine to function as a Ground Power Unit (GPU) to provide electrical power and air conditioning on the ramp without the danger of a spinning propeller.
- Fast & Secure Propeller Locking: Engineered to bring a freely windmilling propeller to a complete stop in seconds, preventing potential damage to the propeller gearbox from prolonged, unlubricated windmilling and enhancing safety during post-shutdown procedures.
- High-Strength, High-Temperature Materials: Constructed from high-strength steel alloys and specialized friction materials designed to withstand the high torque loads and residual heat of the engine gearbox, ensuring reliable performance and a long service life.
- Genuine OEM System: As a genuine OEM component from the ATR supply chain, it guarantees perfect fitment, certified hydraulic performance, and seamless integration with the aircraft's hydraulic and cockpit control systems.

Aircraft Compatibility
The FE201-6-002 is a specific system component for the ATR family of regional turboprop airliners. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification.
- Primary Aircraft Models:
- ATR 42 (all series)
- ATR 72 (all series)
Applications
The FE201-6-002 is a critical system for ground safety and operational flexibility:
- Ground Power Operations: Enables the aircraft to self-provide power and air conditioning at airports with limited ground support, reducing operational costs.
- Ground Safety: Its most critical application is ensuring the propeller is completely stationary when ground crew are working near the #2 engine in Hotel Mode.
- System Maintenance: A key component to inspect, test, and overhaul as part of the aircraft's regular maintenance program to ensure its reliability.
Why Choose FE201-6-002?
The safety of ground personnel is paramount. The propeller brake is the single system that guarantees the propeller will not rotate during Hotel Mode operations. A failure of this brake would create an extremely dangerous situation on the ramp. Using a genuine OEM FE201-6-002 assembly is the only way to ensure the component has the certified hydraulic integrity, correct friction materials, and robust construction to reliably hold the immense torque of a turboprop engine. For a system this critical to ground safety, there is no substitute for a fully traceable, certified OEM assembly.

The "Hotel Mode" capability enabled by the FE201-6-002 propeller brake is a significant operational and economic advantage for ATR operators. In a typical turboprop engine like the Pratt & Whitney Canada PW100 series used on the ATR, the propeller is driven by the power turbine section, which is not mechanically connected to the gas generator (compressor/gas turbine) section. By engaging the propeller brake to lock the power turbine and propeller, the gas generator can be run independently on the ground. This allows the engine's large starter-generator to produce ample electrical power for the entire aircraft, including air conditioning, without the fuel burn, noise, and danger of a spinning propeller. The integrity of the FE201-6-002 brake is the key that unlocks this capability.
Note: This is a flight-critical safety system. Installation, servicing, and testing must be performed by a certified A&P or AME mechanic holding the appropriate ratings and in strict accordance with the current ATR maintenance manual. The hydraulic system must be properly bled and function-tested after installation.
