Aircraft-based modular door panel assembly

A modular door panel assembly for an aircraft, comprising:

• a door surround, wherein the door surround interfaces with a door aperture of the aircraft to ensure aircraft pressurization;
• a first hole in an upper portion of the door surround, wherein the first hole is configured to accommodate a modular upper panel assembly such that a portion of the door surround around the first hole is capable of interfacing with the modular upper panel assembly to ensure aircraft pressurization;
• a second hole in a lower portion of the door surround, wherein the second hole is configured to accommodate a modular lower panel assembly such that a portion of the door surround around the second hole is capable of interfacing with the modular lower panel assembly to ensure aircraft pressurization;
• and
• a strut actuator aperture, wherein the strut actuator aperture is below the second hole and is configured to interface with an articulated strut to ensure pressurization.
