An aircraft interior fitting component system (10) comprises an aircraft interior fitting component (12), a support element (20) attached to the aircraft interior fitting component (12) and an aircraft primary structure component (16). The support element (20) is dimensioned in such a way and is attached to the aircraft interior fitting component (12) in such a position that, in an assembled state of the aircraft interior fitting component (12) in an aircraft, it is supported on the aircraft primary structure component (16) at least when a predetermined load acts on the aircraft interior fitting component (12) along the x-axis of the aircraft in flight direction.
