FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Proposed element comprises stringers (20, 30, 40, 50, 60) extending in lengthwise direction of fuselage and ribs (80) extending across stringers (20, 30, 40, 50, 60) and along fuselage circle. Stringers (30, 40, 50, 60) are shaped to mounting rail for elements (100, 110). Elements (100, 110) should be mounted in fuselage. Said elements represents cabin system devices and components, baggage compartments arranged above passengers' heads and other system devices of aircraft functional infrastructure. Stringer (40) composed of mounting rail has head part (41) extending in lengthwise direction between ribs (80) to terminate at ribs (80) in mounting recesses (42). Said recesses accommodate ribs (80).
EFFECT: higher flexibility in assembly.
