0513039-7 – Textron Aviation Cabin Accessory Power Receptacle Assembly
Available now on the Airparts.aero Marketplace.
The 0513039-7 is a genuine Textron Aviation (Cessna) OEM accessory power receptacle assembly. While styled after a traditional "cigarette lighter," this component is engineered as a flight-certified power source for operating approved portable electronic devices in the cockpit. It provides a reliable and safe connection to the aircraft's 14-volt or 28-volt DC electrical system, enabling the use of portable GPS units, Electronic Flight Bags (EFBs), charging devices, and other approved equipment.
This is not a simple automotive part; it is a robust, aviation-grade assembly manufactured to Textron's exact specifications. It features a durable, plated-steel receptacle and a high-temperature, fire-retardant insulating base designed to prevent short circuits behind the instrument panel. As a component of the aircraft's certified electrical system, it is designed to work in concert with a dedicated circuit breaker to ensure protection against overloads and electrical faults.

Why Choose 0513039-7?
Choosing the genuine Textron 0513039-7 is a critical decision for electrical safety. A cockpit fire is one of the most hazardous in-flight emergencies. Using a non-certified, automotive-grade lighter socket introduces a significant risk, as it may not be made from the same fire-retardant materials, may not be rated for the continuous current loads of aviation devices, and can be prone to short-circuiting in the high-vibration environment of an aircraft. The genuine OEM part is the only way to guarantee that the component meets the FAA's material and safety standards for the aircraft's certified electrical system.
The 0513039-7 receptacle is the termination point of a carefully engineered electrical circuit designed for safety. The aircraft's wiring diagram manual specifies a precise wire gauge (e.g., 18 or 16 AWG) for this circuit, which is selected based on the principles of ampacity—the wire's ability to carry a specific current without exceeding its temperature limit. This circuit is protected by a thermal circuit breaker of a specific amperage. This breaker is a temperature-sensitive device containing a bimetallic strip; if the current draw exceeds the rated value for a period of time, the strip heats up, bends, and trips a switch, opening the circuit. The breaker's trip curve is coordinated with the wire's thermal limits. The OEM receptacle is a known quantity in this engineered system, designed with fire-retardant insulators and robust terminals that will not fail under the maximum rated load. Using a non-certified socket of unknown material properties or internal resistance can create a "weak link" that could overheat and cause a fire behind the instrument panel before the circuit's primary protective device (the breaker) has a chance to trip.
Note: This is a component of the aircraft's certified electrical system. The maximum current rating for this socket is placarded near the receptacle and specified in the POH/AFM. This limit MUST NOT be exceeded. Overloading the circuit will cause the circuit breaker to trip and could lead to a loss of power to essential navigation or communication devices. All electrical work must be performed by a certified A&P or avionics technician in accordance with the Textron/Cessna maintenance and wiring diagram manuals.
