Airfoil attachment comprising a support (3) and flanks (13, 14) rising on it to delimit a broach compartment (15) designed to receive and hold an airfoil root. The flanks (13, 14) are machined (21, 22) so as to separate the portions (23, 24 and 25) and prevent a complete break of a flank and detachment of the airfoil when a crack develops because the crack is stopped by one of the notches.
