Product Description
The 390-521230-0001 is a tube assembly for hydraulic blowdown return circuits in aircraft landing gear systems. This component routes low-pressure fluid from blowdown actuators back to the reservoir during emergency gear extension procedures. The assembly connects between blowdown components and the return manifold, providing a dedicated flow path that prevents system pressure spikes.
Installation follows ISO 8575 and SAE ARP994B specifications with fittings torqued per aircraft maintenance manual requirements. Typical aircraft use this assembly as part of emergency extension backup systems.
