Abstract
A removable secondary aircraft fuel tank enclosure is provided which comprises a pair of substantially flat panels supported within the aircraft fuselage beneath the center wing tank and joined to each other to form a drip pan having a shallow trough for collecting liquid seepage from the tank. A drain line communicates with the trough for discharging liquid collections overboard. An upright removal panel attached to the aircraft structure sealably joins the drip pan fore and aft and means adjacent the enclosure seal the sides of the drip pan against the aircraft structure. Sponge rubber provides a peripheral seal on the flat panels and a plurality of peripheral overcenter fasteners support the drip panel and seals it to the end panels and aircraft structure.
