5600-9C1A-Y0N – Bombardier OEM High-Pressure Oxygen Cylinder
Available now on the Airparts.aero Marketplace.
The Bombardier 5600-9C1A-Y0N is a flight-critical, high-pressure oxygen storage cylinder engineered for the emergency life-support systems of business and regional aircraft. Manufactured by Avox Systems (Zodiac/Safran) as an Original Equipment Manufacturer (OEM) component, this cylinder is the primary reservoir for the flight deck and passenger oxygen systems. In the event of a rapid cabin decompression at high altitudes, the 5600-9C1A-Y0N provides the regulated flow of breathable oxygen required for the flight crew to perform an emergency descent and for passengers to maintain consciousness.
Constructed from high-strength 4130 alloy steel or a specialized composite wrap (depending on the specific "Y0N" modification status), this bottle is designed to store gaseous oxygen at a nominal pressure of 1,850 PSI. The 5600-9C1A-Y0N features a precision-machined neck to accommodate a high-pressure regulator and shut-off valve assembly, ensuring a leak-proof interface under the extreme vibration and thermal cycling characteristic of turbine aircraft environments.
Key Features
Aviation-Grade Steel/Composite Construction: Engineered to provide a high strength-to-weight ratio while meeting the stringent "shatter-proof" requirements of FAA/EASA certification.
1,850 PSI Working Pressure: Calibrated for high-density gaseous storage, providing the required "man-minutes" of oxygen flow mandated for long-range over-water or high-altitude operations.
Corrosion-Resistant Interior: The internal surface is specially treated to prevent oxidation, ensuring the stored oxygen remains "Aviator's Breathing Oxygen" grade, free from particulate and moisture.
High-Visibility Safety Finish: Finished in iconic "Oxygen Green" (FED-STD-595) for rapid identification by ground crews and maintenance technicians.
Integrated Burst-Disc Protection: Designed to interface with safety relief assemblies that prevent catastrophic cylinder failure in the event of over-pressurization due to extreme heat or regulator malfunction.

Applications
The 5600-9C1A-Y0N is utilized for Emergency Life Support. Its primary roles include:
Crew Oxygen Supply: Providing on-demand or constant-flow oxygen to the pilot’s "quick-donning" masks.
Passenger Oxygen System: Serving as the source for the drop-down masks in the cabin during a decompression event.
Therapeutic Oxygen: Supplying low-flow oxygen for medical or first-aid use during flight.
Why Choose 5600-9C1A-Y0N?
Choosing the genuine Bombardier 5600-9C1A-Y0N ensures that the bottle's center of gravity and weight match the aircraft's certified "Weight and Balance" data. Non-OEM bottles may have different thread pitches or shoulder geometries that can lead to "cross-threading" or improper regulator seating, resulting in slow-growth leaks. Furthermore, the 5600-9C1A-Y0N is manufactured to resist the adiabatic heating effects that occur during rapid filling, preventing the structural fatigue that can compromise the bottle’s integrity over time.
The 5600-9C1A-Y0N operates on the principle of Gaseous Compression governed by the Ideal Gas Law ($PV = nRT$). At 1,850 PSI, the molecules of oxygen are packed tightly enough to provide several hours of life support within a relatively small volume. The "Y0N" designation indicates a specific valve-interface profile designed to prevent the installation of non-compatible regulators. The physics of the bottle design account for Isentropic Expansion—as oxygen is drawn from the bottle, the remaining gas cools. The material properties of the 5600-9C1A-Y0N are specifically chosen to maintain ductility at these low temperatures, ensuring the bottle does not become "brittle" and fail during the high-flow requirements of a rapid emergency descent.
Note: This is a hazardous, high-pressure component. Shipping requires Hazmat Class 2.2 (Non-flammable gas) certification. Installation must be performed by a certified A&P/AME. Never use oil, grease, or hydrocarbon-based sealants on oxygen fittings, as this can cause a spontaneous explosion (Oxygen-Oil fire). Before installation, verify the bottle's hydrostatic test date is current. Ensure the bottle is properly "bonded" to the airframe to prevent static discharge.
