ABSTRACT:
A novel door assembly is provided for allowing selective access between adjacent fuel cells of an aircraft. The assembly includes a frame which is adapted to be mounted to the fuel cell rib between adjacent fuel cells. A door is provided for rotational engagement with the frame to thereby provide a sealable throughway between adjacent fuel cells. The door includes first and second handles mounted to respective first and second sides thereof. A latch is mounted to the frame for engaging the second handle to prevent clockwise rotation of the door and thereby latch the door in the sealed positioned. A novel leakage assembly is provided which is responsive to a first predetermined displacement of either the first or second handle to unlatch the door and is responsive to a second predetermined displacement of either the first or second handle to rotate the door in the clockwise direction to free the door from the frame. Accordingly, the door may be latched or unlatched from either side thereof.
