MC0510105-70 - McFarlane FAA-PMA Elevator Trim Cable Assembly Replaces Textron 0510105-70

MC0510105-70 – McFarlane FAA-PMA Elevator Trim Cable Assembly (Replaces Textron 0510105-70)

Available now on the Airparts.aero Marketplace.

The MC0510105-70 is a premium, FAA-PMA certified elevator trim tab control cable assembly from McFarlane Aviation. It is critical for technicians and procurement specialists to correctly identify this part, as it is a flight control component and is not a parking brake cable. This assembly is engineered as a direct, high-quality replacement for the Textron (Cessna) OEM part number 0510105-70. As a leader in the PMA market, McFarlane has built a reputation for producing components that meet or exceed the quality and performance of the original parts.

This assembly provides the essential mechanical linkage between the pilot's trim wheel and the elevator trim tab. It is meticulously constructed from high-strength, corrosion-resistant stainless steel wire rope and includes all necessary pre-swaged terminals and a roller chain section. The integrity of this cable is paramount for the proper function of the secondary flight controls, and the McFarlane PMA alternative offers a certified, airworthy, and cost-effective solution for replacement.

• Cessna 180, 182 Skylane, 185 Skywagon

• Cessna 206 Stationair, 207 Skywagon

• Cessna 210 Centurion

Crucial Note: The official FAA-PMA supplement for this part and the specific aircraft's Illustrated Parts Catalog (IPC) are the final authorities for verifying installation eligibility.

Applications

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

• Direct replacement for worn, corroded, or damaged OEM elevator trim cables.

Why Choose MC0510105-70?

Choosing the McFarlane MC0510105-70 is a decision for quality, value, and trust. A failure of the elevator trim system can dramatically increase pilot workload, especially in demanding flight conditions. McFarlane Aviation is a trusted leader in the PMA community, with a long-standing reputation for producing parts that are engineered to last. This FAA-PMA certified cable assembly guarantees the correct material, the integrity of the factory-swaged fittings, and the precise length required for proper rigging, providing a safe, reliable, and economical solution for your aircraft.

The selection of 7x19 construction for the MC0510105-70 cable is a deliberate engineering choice to maximize fatigue life, a requirement to gain FAA-PMA approval. 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.
