Abstract
An airfoil attachment including a support and flanks rising on it to delimit a broach compartment designed to receive and hold an airfoil root is provided. The flanks are machined so as to separate the portions 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.
