An aircraft includes a first structure between a pressure-controlled region of the aircraft and a non-pressure-controlled region of the aircraft and a second structure between the non-pressure-controlled region and an exterior of the aircraft. The aircraft also includes a first door assembly that includes a first door configured to cover a first opening between the pressure-controlled region and the non-pressure-controlled region and a second door configured to cover a second opening between the non-pressure-controlled region and the exterior. The aircraft further includes a spring coupled, via a first member, to the first door assembly and coupled, via a mechanical linkage, to the second door. The spring is configured to apply a first force to the first member and to apply a second force, via the mechanical linkage, to the second door, where the second force is applied based on a state of the first door assembly.
