1. A pressure relief latch comprising: a housing having a first axial end and a second axial end, the housing comprising a base, a first radial wall, and a second radial wall, the base extending between the first axial end and the second axial end, the base comprising a mating surface and an interior surface opposite the mating surface, the first radial wall and the second radial wall extending radially from the interior surface, the first radial wall spaced from the second radial wall, the housing further comprising a radially extending slot extending through the base from the interior surface to the mating surface; a bolt coupled to the first radial wall and the second radial wall of the housing about a first axis and rotatable about the first axis between a first bolt position and a second bolt position, the bolt comprising a bearing centered about a second axis, the bearing configured to rotate about the second axis, the bolt further comprising a second bolt end configured to be positioned within the radially extending slot of the housing when the bolt is in the first bolt position and positioned outside the radially extending slot of the housing when the bolt is in the second bolt position, wherein the interior surface faces the bearing with the bolt in the first bolt position and the mating surface faces the bearing with the bolt in the second bolt position; and a spring assembly comprising a first assembly end mounted to the bearing and a second assembly end in rotational communication with the housing about a third axis, the spring assembly rotatable about the second and third axes and further comprising a spring extending between the first and second assembly ends.
