Systems and methods for linkage controlling access panel on commercial aircraft

A method comprising:

• moving an aircraft panel from a closed position to an open position, wherein movement of the aircraft panel from the closed position to the open position is controlled by a hinge linkage configured to couple an aircraft beam to an aircraft panel, the hinge linkage comprising:
• an aircraft beam fitting configured to couple to a web of the aircraft beam and be disposed between an upper flange and a lower flange of the aircraft beam;
• an aircraft panel fitting coupled to the aircraft panel;
• a plurality of links coupling the aircraft beam fitting to the aircraft panel fitting and configured to articulate to move the aircraft panel between at least a closed position and an open position, wherein an edge of the aircraft panel is substantially aligned with a portion of the aircraft beam web in the closed position;
• and
• the plurality of links comprises first and second joint assemblies each comprising associated first and second joint hold open locations, the first and second joint hold open locations configured to align with each other when the aircraft panel is moved to the open position to receive a locking pin to lock the first and second joint assemblies together and hold the aircraft panel in the open position.
