130909B280 – Textron Aviation Magnetic Particle Inspected Close Tolerance Bolt

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 130909B280 is a genuine OEM, flight-critical structural bolt, representing the highest echelon of aerospace fastener technology. It is engineered for high-stress, high-fatigue applications within the primary structures of Beechcraft King Air aircraft, particularly in landing gear assemblies. This bolt uniquely combines two critical safety features: it is a close tolerance fastener for precision shear load applications, and it is subjected to 100% Magnetic Particle Inspection (MPI) to ensure absolute material integrity. Manufactured from ultra-high-strength steel, this proprietary bolt is designed to provide the ultimate reliability in the most demanding structural joints.

Key Features

• Close Tolerance Shank: The shank diameter is ground to an exceptionally tight tolerance (typically within 0.0005 inches of nominal). This creates a near line-to-line fit in a precision-reamed hole, preventing any slippage or movement in the joint and ensuring shear loads are borne directly by the bolt's shank.
• Non-Destructive Tested (NDT): Each bolt is subjected to Magnetic Particle Inspection (MPI) after manufacturing. This rigorous quality control process guarantees the fastener is free from microscopic cracks, seams, or material inclusions that could lead to fatigue failure under the severe shock loads of landing and ground operations.
• Ultra High-Strength Steel Alloy: Fabricated from a premium, aircraft-grade VAR (Vacuum-Arc Remelt) steel alloy, such as H-11 or similar, and heat-treated to achieve an exceptionally high tensile strength (often in the 180,000 - 200,000 PSI range or more).
• Superior Corrosion Protection: Plated with a robust, multi-layer finish (typically a diffused nickel-cadmium plating or similar high-performance coating) that provides exceptional corrosion resistance and prevents hydrogen embrittlement, a critical consideration for high-strength steels.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees conformance to the exact material specifications, heat treatment, NDT inspection, and dimensional tolerances required by the aircraft's original Type Certificate.

List not comprehensive, may be applicable on other models.

Applications

This bolt is reserved for the most demanding structural connections where both precision fit and material perfection are non-negotiable:

• Primary Structure Shear Joints: Used to join major structural components that transfer loads primarily through shear forces, such as wing-to-fuselage fittings and control surface hinges.
• Landing Gear Systems: A critical fastener in the assembly of main and nose landing gear torque links, trunnions, and shock struts, where any play or movement would be detrimental to structural integrity and ground handling.
• Flight-Critical Repairs: The only acceptable hardware for use when performing structural repairs or replacing time-lifed components in accordance with the aircraft's structural repair manual.

Why Choose 130909B280?

In a critical shear joint like those found in landing gear, any movement can lead to shock loading and accelerated fatigue, while a hidden material flaw can lead to sudden failure. The 130909B280 addresses both risks by combining a close tolerance design with NDT inspection. Using a genuine Textron Aviation OEM part is the only way to ensure you are installing a fastener with a known, verified, and traceable record of both dimensional precision and material integrity. The safety of the aircraft depends on the uncompromising quality of hardware like this.

SEO-Enhanced Addendum

The engineering principle of the 130909B280 bolt is to create a near-perfect "bearing-type" connection. In a shear joint, the hole is precision-reamed to a specific diameter, and the close tolerance shank of the bolt fits into this hole with minimal clearance. This ensures that when a shear load is applied, it is immediately borne by the cross-sectional area of the bolt shank against the wall of the hole, preventing the joint from slipping into bearing. This prevents shock loading and ovalization of the hole over time. Combining this precision fit with the 100% assurance against micro-cracks from MPI provides the highest possible level of structural integrity and fatigue resistance for a bolted joint.

Note: This is a flight-critical structural component, often with a specific life limit, requiring mandatory replacement after a certain number of flight hours or cycles. It must only be installed in a precision-reamed hole as specified by the aircraft manufacturer's maintenance or structural repair manual. Installation requires the use of a calibrated torque wrench and a new, corresponding high-strength nut and washer, torqued to the precise value specified in the manual.
