The present disclosure provides an aircraft security door as well as methods, systems and apparatus for handling an aircraft security door. In one implementation, a method for installing an aircraft security door onto an aircraft is disclosed. The method includes transferring the aircraft security door to an aircraft service stair, supporting the aircraft security door by a bridge crane coupled to the aircraft service stair, positioning the aircraft service stair in proximity to a fuselage of the aircraft adjacent to an opening in the fuselage, positioning the aircraft security door relative to the opening using the bridge crane, and securing the aircraft security door to the opening.

Systems and methods for attaching to a surface and applying a calibrated load are described. An example system for attaching to a surface and applying a calibrated load includes a suction cup to attach to an attachment surface and a rocker arm to apply a load to a working surface. The rocker arm is coupled to the suction cup and comprises a portion extending over the suction cup to apply pressure over the suction cup. The system also includes a force scale coupled to the rocker arm to provide an indication of an amount of the load applied to the working surface by the rocker arm.

Lock assemblies for locking female drive receptacles include a portion with a feature that is configured to permit selective insertion of the portion of the lock assembly into the female drive receptacle when the portion is in a first rotational orientation and to selectively restrict removal of the portion from the non-circular receptacle when the portion is in a second rotational orientation that is offset from the first rotational orientation. The lock assembly is configured to receive a padlock to restrict rotation of the portion from the second rotational orientation to the first rotational orientation and thereby lock the lock assembly to the female drive receptacle.

Described herein is an apparatus for transporting and reorienting an object on a base surface includes a first header coupled to a first side of the object, and a second header coupled to a second side of the object. The object is between the first and second headers. Each of the first and second headers includes a first flat surface that is contactable with the base surface for supporting the object in a first orientation, a second flat surface that is contactable with the base surface for supporting the object in a second orientation, and a curved surface that couples the first and second flat surfaces. The curved surface is contactable with the base surface as the object transitions between the first and second orientations. A radius of curvature of the curved surface is based on a position of a center of gravity of the object.
