M81824/1-2 - Textron Aviation OEM Copper Alloy Terminal Butt Splice

M81824/1-2 – Textron Aviation OEM Uninsulated Butt Splice (12-10 AWG)

Available now on the Airparts.aero Marketplace.

Overview

The M81824/1-2 is a military-specification, permanent electrical butt splice that is also supplied with the full certification and traceability of Textron Aviation as an Original Equipment Manufacturer (OEM) component. This high-reliability terminal is engineered to create an in-line, permanent connection for 12 to 10 AWG wires. As an uninsulated splice (per the /1 slash sheet), it is designed for use within protected enclosures or where post-insulation, such as heat shrink tubing, will be applied as part of a larger wiring repair process.

Fabricated from tin-plated, high-conductivity copper alloy, this splice is designed to form a gas-tight, cold-weld connection when installed with specified, calibrated tooling. As a genuine Textron Aviation part, it is the factory-specified component for performing certifiable wiring repairs on Cessna, Beechcraft, and Hawker aircraft, ensuring the integrity of the connection matches that of the original factory-built harness.

Key Features

• Textron Aviation OEM Certified: Guarantees the part is the factory-approved, fully traceable component for the Textron Aviation fleet, ensuring compliance with their engineering and quality standards.

• Military Specification Compliance: Manufactured and qualified in strict accordance with MIL-DTL-81824/1, the highest standard for permanent electrical crimp splices.

• For 12-10 AWG Wire: Precisely dimensioned for the yellow color-code wire range (12 AWG to 10 AWG), ensuring a perfect fit for the specified crimp die.

• High-Conductivity Copper Alloy: Constructed from a premium copper alloy to ensure minimum electrical resistance, prevent overheating, and minimize voltage drop.

• Tin-Plated Finish: Provides excellent corrosion resistance and enhances the electrical performance of the crimp by breaking down oxides during the crimping process.

• Uninsulated Seamless Barrel: The uninsulated design is ideal for custom insulation applications, while the seamless barrel ensures uniform strength and crimp performance.

Aircraft Compatibility

As a Textron Aviation OEM part, this splice is the specified component for wiring repairs across their entire product line.

• Primary Textron Aviation Platforms:

  • Cessna Citation Series Business Jets

  • Beechcraft King Air, Baron, and Bonanza

  • Cessna Caravan and Piston Aircraft

  • Hawker Business Jets

• General Aerospace Usage: As a MIL-SPEC part, it is a fundamental component for any certified wiring repair on any aircraft requiring an uninsulated 12-10 AWG splice.

Note: Verification of applicability is the responsibility of the installer. Always consult the aircraft's current Wiring Diagram Manual and maintenance documentation to confirm the correct part and repair procedure.

Applications

• Permanent in-line splicing of power distribution and heavy-gauge signal wires in Textron Aviation aircraft.

• For use in wiring repairs within protected areas such as avionics bays, junction boxes, and enclosed wire runs.

• Ideal for creating a connection point where post-installation insulation (e.g., heat shrink tubing per SAE-AS23053) is required by the repair scheme.

Why Choose this M81824/1-2?

This component provides the dual assurance of meeting the public MIL-SPEC standard and the specific endorsement of Textron Aviation. This guarantees the splice's performance and ensures you are using the exact component specified in the aircraft's original manufacturing and repair documents. Using non-certified hardware for a wiring repair can compromise the integrity of the entire electrical system and violates airworthiness standards. This OEM part is the certified link in a high-reliability repair.

An airworthy electrical connection is the result of a complete, certified system, not just an individual part. The Textron Aviation OEM M81824/1-2 splice is the cornerstone of this system for a 12-10 AWG repair. Aerospace wiring standards (like those in AC 43.13-1B) mandate a "systems approach" where the wire, the terminal (this splice), the calibrated crimp tool (M22520/1-01), and the technician's training are all controlled variables. The dimensions and material properties of this splice are precisely engineered to perform correctly when crimped by the specified die set. The tool provides a repeatable, full-cycle crimp that cannot be under-crimped, and the die forms the material into a solid, cold-welded mass. Using the OEM-certified splice ensures that this critical link in the system is not compromised, guaranteeing a repair that is both mechanically and electrically equivalent to the original wiring.

Note: This is a flight-critical electrical component. Installation must be performed by a certified A&P or avionics technician trained and qualified in aerospace wiring practices. The use of the specified, calibrated crimp tool and die set is mandatory for an airworthy connection. After crimping, the connection must be insulated if it is not located within an otherwise sealed or protected assembly.
