Disclosed is a vibration damped gas turbine engine airfoil row. The airfoil row, comprising first and second coaxial, circular spools and airfoils extending radially therebetween, is cast in at least one piece and then the second or inner spool is cut between adjacent airfoils. Damping inserts are held in place adjacent the inner surface of the second spool by a retaining means.
