Divided into specific ATA chapters and section numbers for maintenance; for example, the fuselage is segmented into areas like the forward, center, and aft box structures. Structural Analysis & Modeling

The A319 fuselage is a "shrunk" version of the A320, achieved by removing seven frames (four forward and three aft of the wing). This reduces the overall length by approximately compared to the A320. Fuselage Diameter: 3.96 m (13 ft 0 in). Maximum Cabin Width: 3.70 m (12 ft 2 in).

Primarily aluminum alloy (e.g., 2524-T3 skin).

Formal documentation specifically labeled "Airbus A319 Fuselage 1.46" generally refers to technical data found in the Airbus Aircraft Characteristics for Airport and Maintenance Planning (AC) manual or structural analysis reports related to the A319’s "shortened" fuselage design.
