130909B274 – Textron Aviation OEM Magnetic Particle Inspected Aerospace Bolt

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 130909B274 is a genuine OEM, flight-critical structural bolt subjected to rigorous Non-Destructive Testing (NDT) to ensure absolute material integrity. This fastener is specifically designed for high-stress, high-fatigue applications within the landing gear assemblies of various Beechcraft King Air models. The bolt's most critical feature is its mandatory 100% Magnetic Particle Inspection (MPI), a process designed to detect minute surface and near-surface cracks or flaws that are invisible to the naked eye. Manufactured from ultra-high-strength steel, this bolt is engineered to provide the utmost reliability in one of the most demanding structural joints of the aircraft.

Key Features

• Non-Destructive Tested (NDT): Each bolt is subjected to Magnetic Particle Inspection (MPI) post-manufacturing. This quality assurance 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, typically in the range of 180,000 to 200,000 PSI or more.
• Engineered for Landing Gear: Specifically designed for use in primary landing gear structures where the joint's failure would be catastrophic. This includes applications in shock struts, torque links, and gear attachment fittings.
• 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 common failure mode in high-strength steels.
• Genuine Textron OEM Part: As a genuine factory component, it guarantees conformance to the exact material, heat treatment, NDT inspection, and dimensional specifications required by the aircraft's original Type Certificate. There is no substitute for this level of quality assurance.

Applications

This bolt is reserved for the most demanding structural connections on the aircraft:

• Primary Structure Assembly: Used to join major structural components that bear the primary flight and landing loads.
• Landing Gear Systems: A critical fastener in the assembly of main and nose landing gear where shock, shear, and tensile loads are at their most extreme.
• 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 130909B274?

The landing gear is one of the most highly stressed structures on an aircraft. The integrity of the fasteners holding it together is absolutely paramount to safety. The "NDT Inspected" designation means this bolt has been certified to be free of hidden defects that could cause it to fail under stress. Using a genuine Textron Aviation 130909B274 is the only way to ensure you are installing a fastener with a known, verified, and traceable record of material integrity. The safety of the aircraft and its occupants depends on the uncompromising quality of flight-critical hardware like this.

SEO-Enhanced Addendum

The process of Magnetic Particle Inspection (MPI) for a bolt like the 130909B274 involves inducing a strong magnetic field into the ferromagnetic steel part. If there are any surface or near-surface discontinuities (cracks), they will disrupt the flow of the magnetic field, creating a "flux leakage field." A fluid containing fine fluorescent magnetic particles is then applied to the bolt. These particles are attracted to the leakage fields, accumulating directly over any flaws and becoming brightly visible under an ultraviolet (black) light. This non-destructive process provides a highly sensitive and reliable method for ensuring that each individual 130909B274 bolt is free from the microscopic defects that could otherwise become a nucleation site for fatigue crack propagation under the severe cyclical loads experienced by landing gear components.

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 where 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.
