30401102 – Textron Aviation OEM Fire Extinguisher Cartridge Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 30401102 is a genuine OEM, flight-critical fire extinguisher cartridge assembly, commonly known as a "squib." This pyrotechnic device is the primary actuator for the engine fire suppression systems on specific Cessna Citation business jets. When an engine fire is detected and the pilot activates the system, this cartridge fires, generating a rapid burst of high-pressure gas. This pressure instantly ruptures the sealing disc on the fire extinguisher bottle, expelling the Halon extinguishing agent into the engine nacelle to suppress the fire. As a life-limited, explosive-classified component, the 30401102 is one of the most critical safety devices on the aircraft.
Key Features
- Pyrotechnic Actuation: An electrically initiated, explosive device that provides instantaneous and reliable activation of the fire suppression system. This method is far more forceful and reliable than simple solenoid-actuated valves.
- Dual-Port Design: This cartridge is engineered with two discharge ports, allowing a single fire extinguisher bottle to be discharged into either the left (Engine #1) or right (Engine #2) engine nacelle, depending on which of the two electrical initiators is fired.
- Hermetically Sealed Construction: The pyrotechnic charge is hermetically sealed within a robust, corrosion-resistant metal housing. This prevents contamination from moisture or other environmental factors, ensuring its reliability over its entire service life.
- Life-Limited Component: This is a time-sensitive component with a mandatory, factory-defined service life. It must be replaced upon reaching its expiration date to ensure the integrity of the fire suppression system.
- Genuine Textron OEM Part: As the genuine factory-certified component, it guarantees conformance to the stringent performance, reliability, and safety standards required by the FAA and the aircraft's original Type Certificate.

Aircraft Compatibility
The 30401102 is the specified OEM fire extinguisher cartridge for some of the most popular mid-size business jets in the world. Its application is specific and must be verified against the aircraft's Illustrated Parts Catalog (IPC).
- Primary Aircraft Models:
- Cessna Citation XL (Model 560XL)
- Cessna Citation XLS
- Cessna Citation XLS+
Applications
The 30401102 has one singular, safety-of-flight application:
- Engine Fire Suppression: Serves as the trigger for the entire engine fire suppression system. A failure of this component to fire would render the system useless in an engine fire emergency.
- Scheduled Maintenance: Must be tracked and replaced as a life-limited item to maintain the aircraft in an airworthy condition.
Why Choose 30401102?
The engine fire suppression system is one of the most critical emergency systems on a multi-engine jet aircraft. Its ability to function instantly and reliably is paramount. Using a genuine Textron Aviation 30401102 OEM cartridge is the only way to ensure the part has a known, traceable manufacturing history, the correct pyrotechnic charge, and a certified service life. There is absolutely no substitute for a genuine, in-date cartridge when it comes to protecting the aircraft and the lives of its crew and passengers.

The 30401102 cartridge is an electro-pyrotechnic device. Internally, it contains a primary explosive charge initiated by a "bridge wire." When the pilot activates the fire handle, an electrical current rapidly heats this bridge wire to incandescence, igniting the primary charge. This sets off the main gas-generating charge within the cartridge body. The resulting high-pressure gas pulse is directed through one of the two ports, where it acts upon a piston or diaphragm that instantly severs the rupture disc of the Halon bottle. This entire sequence occurs in milliseconds. The dual-port design is a weight-saving measure, allowing a single bottle to provide coverage for either engine, with the flight deck controls determining which of the two initiators on the cartridge receives the electrical signal.
Note: This is a flight-critical and hazardous material component. Handling, shipping, and installation must be performed by certified and appropriately trained personnel in accordance with all applicable FAA and DOT regulations. The component's expiration date must be strictly observed and documented in the aircraft's permanent records.
