101-524093-1 – Textron Aviation Elevator Control Clevis Tab for King Air Aircraft

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 101-524093-1 is a genuine OEM, flight-critical elevator control clevis tab, a primary structural linkage engineered for the flight control systems of the Beechcraft King Air series. This is not a simple bracket; it is a high-strength, fatigue-rated component that serves as a pivotal connection point within the elevator control system. It is designed to transfer push-pull inputs from the control rods to the elevator control horn, directly translating pilot or autopilot commands into pitch control surface deflection. Manufactured from a high-strength, forged steel alloy and machined to exacting tolerances, the 101-524093-1 is fundamental to the precise and reliable operation of the aircraft's primary flight controls.

The integrity of this component is essential for safe flight, as it forms a direct link in the chain of control between the pilot's yoke and the aircraft's primary pitch control surface. As a genuine Textron OEM part, it guarantees the certified material strength, dimensional accuracy, and quality control required for this flight-critical application.

Key Features

• Primary Flight Control Component: A critical linkage in the elevator control system. The integrity and precision of this part are directly responsible for the positive feel and immediate response of the aircraft's pitch control.

• High-Strength Forged Steel: Fabricated from a solid billet of high-strength, aerospace-grade steel alloy using a high-pressure forging process. This creates a dense, oriented grain structure that provides exceptional strength and resistance to fatigue cracking from the millions of small control movements it experiences.

• Precision CNC Machining: The forging is then precision-machined on a multi-axis CNC mill to create the exact final shape. This includes boring the pivot and attachment holes to an extremely tight tolerance to ensure a smooth, "zero-slop" connection with mating bolts and bearings.

• Corrosion-Resistant Plating: Plated with a durable cadmium finish to provide robust protection against corrosion, ensuring a long and reliable service life within the empennage structure.

• Non-Destructive Tested (NDT): As a flight-critical structural component, each clevis tab is subjected to 100% Non-Destructive Testing, such as Magnetic Particle Inspection (MPI), to guarantee it is free from any microscopic cracks or material flaws.

Applications

The 101-524093-1 is a flight-critical component essential for the integrity of the primary flight control system:

• Flight Control Maintenance & Repair: Replaced to eliminate "slop" or "play" in the elevator system, which can result from wear at the pivot points. This restores a crisp, positive control feel.

• Mandatory Inspection Item: Subject to rigorous inspection for any signs of corrosion, damage, or cracking during detailed airframe inspections.

• Structural Repair: The only certified part for use when performing a structural repair or overhaul of the elevator control system.

Why Choose 101-524093-1?

The safety of flight is directly dependent on the integrity of the primary flight controls. A failure of a control linkage component like the 101-524093-1 would result in a loss of pitch control. Using a genuine Textron Aviation OEM part is the only way to ensure the component has the certified material strength, proper heat treatment, and precision-machined tolerances required for this flight-critical application. There is no substitute for the quality and airworthiness assurance of a genuine OEM flight control component.

The 101-524093-1 clevis tab functions as a simple but critical machine element: a bifurcated lug designed to accept a tang, rod end, or bearing, secured by a pin or bolt. Its "U" shape allows it to create a pivotal joint that can handle high tensile and compressive loads with minimal side-to-side play. In the King Air's elevator system, it translates the linear "push-pull" motion from the control column, through a series of rods and bellcranks, into the rotational motion of the elevator itself. The precision of the bored holes for the pivot bolt is the most critical dimensional feature. This bore is machined to a tolerance of thousandths of an inch to ensure a snug fit with the bolt, eliminating "slop" (lost motion). This precision is fundamental to the direct, responsive feel of the aircraft's pitch control.

Note: This is a flight-critical flight control system component. Installation must be performed by a certified A&P mechanic with experience in Beechcraft flight control systems, in strict accordance with the current Textron Aviation (Beechcraft) maintenance manual. Proper rigging and a full flight control movement check are mandatory after installation.
