The Irkutsk Aviation Plant (IAP) continues to advance the production of the MC-21 passenger aircraft with the assembly of new fuselage sections. Currently, specialists in Shop 205 are focused on assembling the three primary fuselage sections: F1, F2, and F4A. Once assembled, these sections will be sent to a dedicated painting facility before moving on to final integration.
The F2 section is in the early stages of assembly, with technicians riveting the longitudinal joint between sections 2 and 3. According to the plant’s internal newsletter, *Irkutsk Aircraft Builder*, the next steps include installing fasteners on the floor grid, positioning and attaching section 1, riveting the longitudinal joints between section 1 and sections 2 and 3, fitting the emergency exit opening, and simultaneously installing the baggage compartment components.
After completing these tasks, the F2 section will be transferred for further assembly and integration with other fuselage components of the MS-21. Meanwhile, the F1 section is also underway, with all three of its subsections already positioned in the main assembly jig. This assembly is expected to be ready for transfer to Shop 208 within three weeks, where it will undergo preparation, painting, and drying.
The F4A section, having completed assembly, is currently being cleaned in preparation for painting. Once painted, it will be moved to Shop 246 for mating with other fuselage elements.
The MC-21 assembly process at Irkutsk Aviation Plant incorporates cutting-edge technology. Precision jigs and automated riveting systems help minimize defects and speed up installation. Shop 205 operates on a modular assembly principle, enabling simultaneous work on different sections and reducing overall production time.
Digital monitoring systems have been implemented to streamline assembly operations. Sensors track riveting and welding parameters in real time, allowing for immediate detection and correction of any deviations. These innovations reduce downtime and boost productivity.
Logistics within the plant have also been optimized. Automated transport vehicles and modern storage solutions cut down the time needed to move large assemblies between workshops. A unified information system coordinates activities across departments, minimizing delays.
Earlier this March, Shop 205 completed the assembly of the F2 section for aircraft MS.0026. The next priority is finalizing the F4 and F4A sections for the same aircraft.
