9912048-2 – Textron Aviation OEM Fire Extinguisher Cartridge Assembly
Available now on the Airparts.aero Marketplace.
Overview
The Textron Aviation 9912048-2 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 and APU fire suppression systems on the high-speed Cessna Citation X (Model 750) business jet. When an engine or APU fire is detected and the pilot activates the fire handle, 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 nacelle to suppress the fire. As a life-limited, explosive-classified component, the 9912048-2 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, ensuring discharge even under extreme conditions.
- High-Integrity Hermetic Seal: The pyrotechnic charge is hermetically sealed within a robust, corrosion-resistant metal housing. This prevents contamination from moisture, hydraulic fluid, or other environmental factors, guaranteeing 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, regardless of condition, to ensure the integrity of the fire suppression system.
- OEM System Integration: Engineered to integrate perfectly with the Kidde fire suppression system installed on the Citation X, ensuring the correct electrical initiation characteristics and discharge pressure.
- 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.

Applications
The 9912048-2 has one singular, safety-of-flight application:
- Fire Suppression System Actuation: Serves as the trigger for the entire engine and APU fire suppression system. A failure of this component to fire would render the firex bottle useless in an actual fire emergency.
- Scheduled Maintenance: Must be tracked as a life-limited item and replaced to maintain the aircraft in an airworthy condition.
Why Choose 9912048-2?
The engine and APU fire suppression systems are arguably the most critical emergency systems on a transport-category aircraft. Their ability to function instantly and reliably is paramount. Using a genuine Textron Aviation 9912048-2 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 a multi-million dollar asset and the lives of its crew and passengers.

The 9912048-2 cartridge is an electro-pyrotechnic device. Internally, it contains a primary explosive charge initiated by a "bridge wire." When the pilot pulls and 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 into the fire extinguisher bottle head, where it drives a piston that instantly severs the bottle's rupture disc. This entire sequence occurs in milliseconds, allowing the Halon extinguishing agent to flood the engine nacelle almost instantly. The reliability of this pyrotechnic train is why these components carry a strict, non-negotiable service life.
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.
