Rolls Royce did not design the redundant electrical control systems in the wing that failed.
Rolls Royce did not design the hydraulic lines in the wing that failed.
Rolls Royce did not design the brake system which failed.
Rolls Royce did not design the fuel pump system in the wings which failed.
Etc, etc, etc...
