ABSTRACT:
A method and apparatus to install and remove heavy components mounted on a base structure is disclosed. Various construction details are developed which provide means for coupling the component and base structure in a manner permitting relative rotation and translation about an axis of rotation. In one embodiment, an aircraft engine component (18) has a pair of hooks (32) and an aircraft engine (10) has a pair of pins (46) which engage the hooks to couple the component and engine to permit rotational and translational motion of the component relative to the engine. For this embodiment, a method for relative motion between an installed and uninstalled condition is comprised of maneuvering the component and engine between a coupled and uncoupled position, moving the coupled component relative to the engine about the axis of rotation, and manipulating a fastener means between a secured and unsecured position.
