Product Description
The 390-521249-0005 is a hydraulic tube assembly for the emergency landing gear blowdown pressure circuit. This component routes nitrogen pressure from the emergency bottle through the manifold to landing gear actuators, forcing the gear down if main hydraulics fail. The steel tube assembly connects the emergency extension system and withstands high-pressure nitrogen supply.
Installation requires torque verification per aircraft AMM specifications and configuration confirmation in the Illustrated Parts Catalog.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
