Product Description
The 390-521246-0005 is a hydraulic return tube assembly that routes low-pressure fluid from actuators and manifolds back to the reservoir. Constructed with precision-formed tubing and approved fittings, this assembly maintains system integrity during return flow. Installation requires routing and clamping per aircraft maintenance manual specifications and FAA AC 43.13-1B guidance.
The assembly connects downstream of control surfaces, landing gear, and flight control actuators, completing the hydraulic circuit cycle. Proper installation prevents fluid leakage and ensures efficient reservoir return flow in general aviation and commercial aircraft hydraulic systems.
