A fuselage door for a pressurized aircraft fuselage in which the hoop tension loads caused by cabin pressure are carried through the door rather than around the door. Stationary interlocking moldings in the door and fuselage door seat transfer loads through the door-fuselage intersection. The interlocking portions of the moldings have a sloped engaging portion having an angle such that the inward directed force component of tension due to a pressure differential is less than the outward directed force from cabin pressure on the door.

[ I claim:] [1.] A door assembly for a pressurized vessel, the pressurized vessel having a curved vessel wall with an outer surface and a door opening, the door assembly having a door for closing and sealing the door opening in the vessel wall, the door assembly comprising;a door engaging seat facing inward on a perimeter portion of the door opening;a vessel engaging seat facing outward on a perimeter portion of the door which mates with the door engaging seat, the vessel engaging seat abutting and being pressed against the door engaging seat by an outward directed force component resulting from internal pressure in the vessel;the door engaging seat having a door engaging face which faces inward and away from the opening and is oriented at a selected acute angle relative to a line perpendicular to a portion of the outer surface of the vessel wall nearest the door engaging seat; andthe vessel engaging seat having a vessel engaging face parallel to and mating with the door engaging face when the door is closed, wherein the internal pressure in the vessel creates tension which is transferred by the mating faces through the door.
