856A3940G01 is a heavy-duty aerospace structural bracket, engineered to AS9100D aerospace manufacturing standards and FAA AC 43.13-2B requirements, specifically designed for the fuselage support system of Boeing 737NG aircraft.

Fabricated from aerospace-grade 7075-T6 aluminum alloy with a chromate conversion coating for corrosion resistance, it withstands static loads up to 180 kN and operates in temperatures from -55°C to 130°C, ensuring structural integrity in extreme flight and ground conditions. With a precision-machined length of 285 mm and width of 120 mm, it serves as a critical connection between the fuselage frame and wing root support structure, absorbing aerodynamic and landing stresses. Weighing 4.2 kg, its lightweight design balances strength and efficiency, making it an essential component for MRO technicians during fuselage structural maintenance, safeguarding aircraft structural stability and flight safety.
