Method and mounting system for mounting a profile component on an aircraft structural component

A mounting system for mounting a profile component on an internal frame structural component of an aircraft, wherein the mounting system comprises:

• a robot arm installed outside the aircraft;
• a tool holder arranged at a free end of the robot arm and sized and configured to be guided through an opening in an outer skin of the aircraft into an interior of the aircraft by the robot arm, wherein the tool holder comprises a C-shape or U-shape with an open end;
• a gripping device arranged on the tool holder and configured to pick-up and release the profile component;
• at least one rail, wherein the gripping device moves, along a top surface of the at least one rail, away from or toward the profile component;
• a fastener device arranged on the open end of the tool holder and configured to attach fastening means to fasten the profile component to the internal frame structural component;
• a control unit coupled to the robot arm, the tool holder, the gripping device and the fastener device and configured to guide the robot arm through the outer skin of the aircraft into an interior of the aircraft, align the profile component by the tool holder relative to the internal frame structural component, and arrange the profile component in an installed position on the internal frame structural component;
• and, a first pressing unit and a second pressing unit configured to press the profile component onto the internal frame structural component in the installed position from two directions substantially perpendicular to one another.
