Unsafe Condition
Lugs of the assembly nut, part number A2621005000200, were inverted during manufacturing, leading to the illusion of correct torque while the parts are not properly connected. This could result in a loose connection, loss of fire extinguishing system integrity, and inability to ensure adequate agent concentration, potentially causing a temporary uncontrolled engine fire.
