A method of assembling a rotor blade includes determining first spanwise and chordwise moments of a first component of the blade and comparing the first spanwise and chordwise moments to respective target first spanwise and chordwise moments. The first spanwise and/or chordwise moment(s) of the first component is/are adjusted based upon corresponding results of the comparison to provide balancing of the first component. Second spanwise and chordwise moments of a second component of the blade are determined and compared to respective target second spanwise and chordwise moments. The second spanwise and/or chordwise moment(s) of the second component is/are adjusted based upon corresponding results of the comparison to provide balancing of the second component. The balanced first and second components are assembled to each other so that target spanwise and chordwise moments of the blade are met.
