Abstract: A method and apparatus contains and drains leakage from fluid system piping on a mobile platform such as an aircraft. A generally U-shaped channel is formed having outwardly oriented edge flanges and either integral or attached end plates. A pair of drain connections is disposed adjacent to each end plate. A group of fluid lines including at least one flammable fluid line is loaded within the U-shaped channel. A cover plate having outwardly oriented edge flanges aligning with the U-shaped channel edge flanges is positioned over the U-shaped channel. The edge flanges of both the cover plate and the U-shaped channel are joined with a seal such that a fluid-tight assembly results. Fluid leakage from any of the group of enclosed fluid lines discharges through the pair of drain connections. One of the end plates forms a firewall connectable to an engine firewall boundary.
