ABSTRACT:
A latch and keeper combination for use with an aircraft panel or the like for joining one member to another member under tension and shear loading. A keeper for attaching to one member and having a bracket with an eye bolt and a bushing included therein, and a latch for attaching to another member and having a housing with cover and a hook, a lever and a shear pin included therein. The hook and lever are rotatably mounted in the housing for rotation about an axis, with the hook having an arcuate finger for engaging the keeper eye bolt, with the shear pin sliding into and out of the keeper bushing and with the lever driving the pin. The hook rotates the lever to a closed position to engage the shear pin with the bushing and to an open position to disengage the shear pin from the bushing. A plunger carried in the housing for translation along the axis, and a spring in the housing for urging the plunger outward along the axis, with plunger and hook providing for locking the hook in the closed position.
