The invention relates to a blade attachment (1, 20) for a bearingless main rotor of a helicopter with an airfoil blade (2), a flexbeam (3, 21) including a flexbeam body (16, 17) and a flexbeam head (13) at an end of said flexbeam body (16, 17). A control cuff (4, 22) encloses and extends along at least a predominant portion of said flexbeam (3, 21). A separable junction arrangement between said flexbeam head (13), said control cuff (4, 22) and said root end of said airfoil blade (2) is mechanical with removable fasteners. Said removable fasteners comprise a main bolt (7) and at least one supporting bolt (8) |
