0455027-1 – Textron Aviation OEM Aileron Bellcrank Bracket
Available now on the Airparts.aero Marketplace.
Overview
The 0455027-1 is a flight-critical, genuine Textron Aviation (Cessna) Original Equipment Manufacturer (OEM) bracket, specifically designed to support the aileron bellcrank within the wing structure. This is a primary flight control component, engineered to provide a robust and precisely located mounting point for the bellcrank assembly, which translates control cable movement into the rotational force that actuates the aileron push-pull rod.
Manufactured from high-strength aluminum alloy (likely 2024-T3 Alclad, confirmation required via OEM documentation) and formed to the exact specifications of Textron's engineering drawings, this bracket is designed to withstand the significant operational loads and vibrational environment of the flight control system. Its structural integrity and correct positioning are paramount for ensuring accurate aileron response and preventing dangerous free play or binding in the roll control system. As the genuine OEM part, the 0455027-1 is the only component guaranteed to meet the material strength, fatigue life, and dimensional tolerances required for this critical application.
Key Features
Genuine Textron Aviation OEM Part: Guarantees the part is the factory-specified and fully certified component, ensuring a perfect fit and uncompromising flight safety.
Primary Flight Control Structure: Serves as the mounting foundation for the aileron bellcrank, a critical node in the roll control system linkage.
Precision-Formed Aluminum Alloy: Manufactured from certified aerospace-grade aluminum alloy, formed on factory tooling for exact dimensions and stress-free installation.

Why Choose 0455027-1?
The bracket supporting a primary flight control bellcrank is a "no-compromise" structural component. Failure due to fatigue cracking or improper fit could lead to a loss of roll control. Only the genuine Textron OEM 0455027-1 is guaranteed to be manufactured from the correct certified material, heat-treated to the proper temper, and formed to the exact dimensions required by the aircraft's type certificate. Using a locally fabricated or non-certified part introduces an unacceptable risk of material failure, incorrect control geometry leading to binding or flutter, and renders the aircraft unairworthy.
The design of the 0455027-1 bracket exemplifies the principle of efficient load transfer in semi-monocoque aircraft structures. The aileron bellcrank experiences significant reaction forces as it translates the tension from the control cables into the push-pull motion of the aileron rod. This bracket is engineered not just to hold the bellcrank pivot bolt but to distribute these concentrated loads effectively into the surrounding wing structure (typically a rib or spar web). The bracket's flanges, bend radii, and fastener hole pattern are meticulously designed using Finite Element Analysis (FEA) to minimize stress concentrations and ensure the loads are transferred smoothly into the shear webs and stiffeners of the wing box. This prevents localized overloading and ensures the long-term fatigue life of both the bracket and the primary wing structure to which it attaches.
Note: This is a primary flight control structural component. Installation must be performed by a certified A&P mechanic, typically requiring riveting, in strict accordance with the aircraft's Structural Repair Manual (SRM) or maintenance manual. When replacing this part, the surrounding structure and existing attachment holes must be carefully inspected for any signs of cracking, elongation, corrosion, or "working" fasteners.
