898052 – Kidde Aerospace 1211 Portable Halon 3lb Aviation Fire Extinguisher

Available now on the Airparts.aero Marketplace.

The Kidde Aerospace 898052 is a flight-critical, 3lb portable fire extinguisher charged with Halon 1211 (Bromochlorodifluoromethane), specifically engineered for the unique cockpit and cabin environments of general aviation, corporate, and commercial aircraft. As the industry standard for airborne fire suppression, Halon 1211 is a "clean agent" that provides a high-velocity, liquefied gas discharge capable of penetrating hard-to-reach areas behind instrument panels and within electrical bays. Unlike dry chemical alternatives, Halon 1211 leaves no corrosive residue, ensuring that sensitive avionics and expensive electronic flight instrument systems (EFIS) remain undamaged during and after a fire event.1

Constructed with a lightweight, high-pressure aluminum cylinder and a precision-machined valve assembly, the 898052 is designed for rapid deployment during in-flight emergencies. Its 3lb capacity provides the optimal balance between portability and suppression capability, meeting the FAA requirements for hand-held fire extinguishers on a wide range of airframes. The unit features an integrated pressure gauge for instantaneous pre-flight inspections and a heavy-duty safety pin to prevent accidental discharge. For aircraft owners and operators, the 898052 represents an indispensable safety component that provides the best possible defense against Class B (flammable liquids) and Class C (electrical) fires.

Key Features

• Halon 1211 Suppression Agent: A chemically stable, liquefied gas that interrupts the combustion chain reaction without causing thermal shock to delicate components.2

• Zero-Residue Discharge: Non-conductive and non-corrosive, preventing secondary damage to expensive aircraft wiring, circuit breakers, and avionics.3

• Lightweight Aluminum Cylinder: Finished with a high-visibility, chemical-resistant red epoxy coating for rapid identification and long-term durability.

• Integrated Pressure Gauge: Allows for immediate verification of the unit’s operational readiness during pre-flight or scheduled inspections.

• Compact 3lb Capacity: Designed to fit standard aviation mounting brackets, providing localized suppression power without significantly impacting the aircraft's weight and balance.

Applications

The 898052 is specifically rated for Class B (Flammable Liquids) and Class C (Live Electrical Equipment) fires. Its primary application is in the Flight Deck and Cabin, where it can be used to suppress engine fires that enter the cabin, fuel-related fires, and electrical fires stemming from avionics racks or overhead panels.

Why Choose 898052?

Choosing a Kidde 898052 ensures you are using a suppression agent specifically approved by the FAA for aviation use. While "ABC" dry chemical extinguishers are common in residential settings, their discharge in a cockpit creates a blinding cloud of corrosive powder that can permanently destroy avionics and hinder the pilot’s ability to see through the windshield. Halon 1211 is the only agent that provides the necessary "knockdown" power for electrical fires while maintaining cockpit visibility and protecting the aircraft's long-term electronic integrity.

The effectiveness of the Kidde 898052 is rooted in the thermodynamics and chemical kinetics of Bromochlorodifluoromethane ($\text{CBrClF}_2$). Unlike water or CO2, which primarily act through cooling or oxygen displacement, Halon 1211 acts as a catalytic chain-breaker. When discharged, the molecule undergoes photolysis, releasing bromine radicals that aggressively react with the free radicals in the fire's flame zone. This process terminates the combustion reaction at a molecular level with extremely low concentrations (typically 5% by volume). From a materials science perspective, Halon 1211 is an electrically non-conductive medium with a high dielectric strength, ensuring it will not cause short-circuits in high-voltage avionics.5 Furthermore, the 898052’s aluminum cylinder is manufactured to DOT-3AL specifications, providing a high burst-pressure-to-weight ratio and excellent resistance to pitting corrosion, essential for components stored in the varied humidity and pressure environments of an unpressurized aircraft cabin.

Note: This is a flight-critical safety component. Maintenance and inspection must be performed in accordance with NFPA 10 and the manufacturer's instructions. The 898052 requires a monthly visual check of the pressure gauge and an annual weight verification by a certified technician. Halon 1211 is a liquefied gas under pressure; avoid breathing the vapors and discharge only in the event of an actual fire.6 Installation of the mounting bracket must be performed by a certified A&P mechanic to ensure it does not interfere with flight controls or egress.
