50-610000-419 – Textron Aviation OEM Elevator Bracket
Available now through the AirParts Aero marketplace.
Overview Section
The Textron Aviation 50-610000-419 is a high-strength OEM Elevator Control Bracket engineered for the primary flight control systems of Beechcraft and Cessna aircraft. This structural component serves as a critical pivot or attachment point within the elevator linkage, translating pilot input from the control column to the elevator surfaces.
Manufactured by Textron Aviation to meet rigorous Part 23/25 certification standards, the 50-610000-419 is a "safety-of-flight" item. It is designed to maintain precise geometry under the significant aerodynamic loads experienced during pitch maneuvers. Its robust construction and anti-corrosive finish ensure long-term durability in the high-vibration environment of the aircraft's tail cone.
Key Features Section
OEM Structural Precision: Fabricated to the exact blueprints of the original airframe manufacturer, ensuring perfect alignment of the control bellcranks and pushrods.
Superior Material Integrity: Forged or machined from aerospace-grade aluminum or alloy steel (per OEM specification) to provide high fatigue resistance and load-bearing capacity.
Corrosion Protection: Finished with a Class 1A Chromate Conversion coating (MIL-DTL-5541) or specialized primer to prevent intergranular corrosion in the hidden areas of the empennage.
Critical Tolerance Machining: Features precision-reamed holes for bushings and pivot bolts, eliminating "slop" in the elevator system and providing the crisp control response pilots expect.
Fatigue Resistant Design: Engineered with specific fillet radii to distribute stress concentrations, preventing the onset of stress-riser cracks over thousands of flight hours.

List not comprehensive, may be applicable on other models.
Technical Applications & Safety
The elevator bracket is the foundation of pitch authority. If this component suffers from wear, corrosion, or deformation, it can lead to "control surface flutter" or, in extreme cases, a mechanical disconnect of the primary flight controls.
Safety Warning: During Annual or 100-hour inspections, the 50-610000-419 must be visually inspected for "smoking rivets" (indicating movement), elongated bolt holes, or any signs of hairline fractures. Because it is located in the tail, it is susceptible to "hidden" corrosion from moisture accumulation in the fuselage; ensure the area remains well-vented and treated with corrosion inhibitors.
Technical Engineering Insight
The engineering value of the 50-610000-419 lies in its Load Path Optimization. In the flight control loop, the bracket acts as the grounded reference for the elevator's mechanical advantage. Textron engineers this part to handle "limit loads" that exceed the standard aerodynamic forces by a safety factor of 1.5.
A key technical detail of the 50-610000-419 is the Surface Hardness of the pivot bore. These bores are often designed to accept a "press-fit" bushing. By using the OEM bracket through AirParts Aero, you ensure the metallurgical grain flow of the metal follows the direction of the control forces, which is essential for preventing catastrophic fatigue failure. Aftermarket or "fabricated" brackets often use plate stock with incorrect grain orientation, significantly lowering the component's cycle life.
Installation & Maintenance Addendum
Bushing Integrity: Check that any mating bushings are not spinning within the bracket bore. If a bushing is loose, the bracket may require replacement to maintain rigging specs.
Fastener Torque: Use only the specified NAS-grade bolts. Ensure the nut is torqued to the "shear" value to avoid over-stressing the bracket ears.
Rigging Check: After installation, a full "Control Surface Travel" check must be performed to ensure the elevator meets the degrees of travel specified in the Type Certificate Data Sheet (TCDS).
