Abstract
An access door assembly includes a door panel located at a door opening and a primary hinge having a primary hinge axis and operably connected to the door panel. A guide track is affixed at the door opening and is operably connected to the door panel to guide rotation of the door panel about the first hinge axis. A secondary hinge having a secondary hinge axis is operably connected to the door panel. The secondary hinge allows for rotation of a first portion of the door panel about the secondary hinge axis, while a second portion of the door panel is stationary.
