Support box apparatus

A support box apparatus for an overhead area of a cabin of an aircraft, the support box apparatus comprising:

• a framework comprising:
• longitudinal members that span forward to aft, wherein the longitudinal members are formed of composite honeycomb sandwich panels;
• transverse members that span inboard to outboard between the longitudinal members, wherein the transverse members are formed of composite honeycomb sandwich panels;
• and
• attachment components configured to couple the longitudinal members or the transverse members to structural components of the aircraft that span inboard to outboard above the longitudinal members and the transverse members;
• electrical wiring attached to the longitudinal members or the transverse members, wherein the electrical wiring is configured to provide electrical connections between an electrical system of the aircraft and electrical components of the aircraft;
• environmental control system (ECS) ducting attached to the longitudinal members or the transverse members, wherein the ECS ducting is configured to provide fluid connections between an environmental control system (ECS) of the aircraft and ECS vents of the aircraft;
• life support lines attached to the longitudinal members or the transverse members, wherein the life support lines are configured to provide fluid connections or electrical connections between a life support system of the aircraft and life support modules of the aircraft;
• and
• a tooling system comprising a base having a first end and a second end resting on one or more brackets on the longitudinal members, wherein the tooling system is configured to raise, lower, and stow one or both of tools used for interior installation tasks or components to be installed in the cabin.
