0510105-70 - Textron Aviation OEM Parking Brake Cable Assembly

0510105-70 – Textron Aviation Elevator Trim Tab Control Cable Assembly

Available now on the Airparts.aero Marketplace.

The 0510105-70 is a genuine Textron Aviation (Cessna) OEM, flight-critical elevator trim tab control cable assembly. It is essential for technicians and procurement specialists to correctly identify this part, as it is a component of the secondary flight control system and is not a parking brake cable. Its purpose is to provide the direct mechanical linkage between the pilot's trim wheel in the cockpit and the elevator trim tab actuator in the empennage, allowing the pilot to make fine adjustments to the aircraft's pitch attitude and relieve control pressures.

This assembly is meticulously constructed from high-strength, corrosion-resistant stainless steel wire rope and includes all necessary pre-swaged terminals and a roller chain section for engagement with the trim wheel sprocket. The integrity of this cable is paramount for the proper function of the secondary flight controls. As a component that is subject to wear and requires periodic inspection, replacement with a genuine Textron OEM assembly is the only way to guarantee the correct length, fittings, and certified quality required for a safe and airworthy repair.

Key Features

• Genuine Textron Aviation OEM Part: Guarantees the precise length, correct end fittings, and certified materials as specified in the aircraft's original type design.

• Flexible 7x19 Stainless Steel Cable: Constructed from 7x19 corrosion-resistant steel (CRES) wire rope, a specific stranding chosen for its superior flexibility and fatigue life when routed around numerous small-diameter pulleys.

• Includes Pre-Swaged Terminals and Chain: Arrives as a complete, ready-to-install assembly with a roller chain section for the trim wheel and all other end fittings permanently swaged at the factory.

• Transmits Pilot Trim Inputs: Provides a direct, reliable mechanical connection for precise control over the elevator trim tab.

• Flight-Critical Component: A core part of the aircraft's secondary flight control system, essential for reducing pilot workload and maintaining stable flight.

Aircraft Compatibility

The 0510105-70 is the specified elevator trim cable assembly for a vast range of Textron Aviation (Cessna) single-engine aircraft. Common applicable models include, but are not limited to:

• Cessna 172 Skyhawk (many models)

• Cessna 180, 182 Skylane, 185 Skywagon

• Cessna 206 Stationair, 207 Skywagon

• Cessna 210 Centurion

Crucial Note: The specific aircraft model and serial number must be checked against the latest revision of the official Textron Aviation (Cessna) Illustrated Parts Catalog (IPC) to ensure correct part number applicability.

Applications

• Primary control cable connecting the cockpit trim wheel to the elevator trim tab actuator.

• Replacement part for cables found to have broken wires, corrosion, fraying, or excessive wear during inspection.

Why Choose 0510105-70?

Choosing the genuine Textron 0510105-70 is an essential decision for flight safety. The elevator trim system is a critical flight control that can dramatically increase pilot workload if it fails, especially in instrument meteorological conditions (IMC) or during an emergency. A worn or corroded cable can fail under tension, rendering the trim system inoperative. The genuine OEM assembly is the only way to guarantee the correct material, the integrity of the factory-swaged fittings (which must hold 100% of the cable's breaking strength), and the precise length required for proper rigging. Using a non-certified or locally fabricated cable introduces unacceptable risks to the flight control system.

The selection of 7x19 construction for the 0510105-70 cable is a deliberate engineering choice to maximize fatigue life. This stranding, which consists of seven smaller strands that are themselves composed of nineteen individual, small-diameter wires, provides exceptional flexibility. The ability of a wire rope to bend repeatedly is inversely proportional to the diameter of its individual wires. As the trim cable travels from the cockpit to the empennage, it is routed around numerous small-diameter pulleys. Each time the cable flexes over a pulley, the outer wires are put into tension and the inner wires into compression. The high wire count and small wire diameter of the 7x19 construction minimize the bending stress on each individual wire, dramatically increasing the cable's resistance to fatigue from repeated flexing. This contrasts with a stiffer cable construction like 1x19 (a single strand of 19 wires), which is excellent for static applications like structural bracing but would fail rapidly from metal fatigue if run over a pulley system.

Note: This is a flight-critical secondary flight control component. It is subject to rigorous inspection for broken wires, corrosion, and wear in accordance with AC 43.13-1B and the aircraft maintenance manual at every annual/100-hour inspection. Installation and rigging of the trim system must be performed by a certified A&P mechanic in strict accordance with the Textron/Cessna maintenance manual. Proper cable tension, set with a tensiometer, is critical for correct system operation and to prevent premature wear.
