A vibration attenuator (301) for attenuating vibrations in a mast of an aircraft is disclosed. The vibration attenuator comprises a first spinner (215) configured for rotation about a first axis; a first mass (307) coupled to the first spinner for rotation therewith, the first mass being movable radially relative to the first axis between an inner position and an outer position; an actuator (311) coupled to the first mass for selectively controlling a radial location of the first mass relative to the axis; and a first motor for driving the first spinner in rotation about the first axis.
