0532105-4 – Textron Aviation ELT Mounting Bracket
Available now on the Airparts.aero Marketplace.
The 0532105-4 is a genuine Textron Aviation (Cessna) OEM structural mounting bracket. This component is specifically designed to securely mount the Emergency Locator Transmitter (ELT) unit within the airframe of a wide range of Cessna single-engine aircraft. Its function is absolutely critical, as it ensures the ELT remains firmly attached to the primary aircraft structure during the high G-loads associated with an accident sequence, allowing the internal G-switch to properly activate the beacon.
Precision-formed from a high-strength aluminum alloy, this bracket is engineered to the exact dimensions and hole patterns required to interface with both the ELT unit and the aircraft's mounting provisions. It is finished with a corrosion-resistant coating to ensure durability in the airframe environment. The structural integrity of the ELT's installation is paramount for its life-saving function, and using the correct, certified OEM bracket is the only way to guarantee this integrity.
Key Features
Genuine Textron Aviation OEM Part: Guarantees the correct material strength, dimensions, and hole patterns required for a secure and compliant ELT installation.
Provides Secure ELT Mounting: Engineered to withstand the significant G-loads specified in crashworthiness standards, ensuring the ELT remains attached and functional after an impact.
High-Strength Aluminum Alloy Construction: Manufactured from a specific aluminum alloy (e.g., 2024-T3 or similar) chosen for its optimal strength-to-weight ratio and fatigue resistance.
Corrosion-Resistant Finish: Typically treated with a chemical conversion coating (Alodine) and/or primer for long-term protection against environmental degradation.
Precision Fit: Designed for a perfect fit with both the ELT unit and the designated airframe mounting location, ensuring a secure, vibration-free installation.

Why Choose 0532105-4?
Choosing the genuine Textron 0532105-4 is a critical decision for ensuring the proper function of a life-saving device. An ELT that separates from the airframe during an accident will likely fail to activate or transmit effectively. The OEM bracket is specifically engineered and tested to withstand the extreme forces of a crash, guaranteeing that the ELT remains secured as designed. Using a non-certified or locally fabricated bracket introduces an unacceptable risk of structural failure at the most critical moment, potentially rendering the ELT useless. The genuine OEM part is the only way to ensure the certified strength and reliability required for this critical safety application.
The design of the 0532105-4 bracket adheres to critical crashworthiness standards mandated by aviation regulations (e.g., 14 CFR § 23.561). These standards require that safety equipment like the ELT remain attached to the airframe under specific forward, downward, sideward, and upward inertial load factors, which simulate the forces experienced during a survivable accident. The bracket is engineered as a load path, transferring these inertial forces from the mass of the ELT unit into the surrounding primary airframe structure. Its material (high-strength aluminum alloy), thickness, bend radii, and fastener locations are all carefully calculated using Finite Element Analysis (FEA) and validated through physical testing to ensure it will not yield or fracture under these extreme, specified G-loads. This structural integrity is essential because the ELT contains an internal G-switch (accelerometer), which is calibrated to automatically activate the beacon upon sensing the characteristic deceleration profile of a crash. If the bracket fails and the ELT detaches, the G-switch may not experience the correct deceleration vector or magnitude required for activation.
Note: This is a flight-critical structural component directly related to the function of emergency equipment. It must be installed using the correct type and quantity of approved fasteners (bolts, nuts, washers) as specified in the maintenance manual, and these fasteners must be torqued to the specified values. Installation location and orientation are critical for proper G-switch function. All work must be performed by a certified A&P mechanic in strict accordance with the Textron/Cessna maintenance manual.
