Abstract

The invention relates to an actuator for operating an access door on an aeroplane, comprising a body (18) fitted with a motor member (20) and with a drive member (24) that is movable relative to the body (18) under the action of the motor member (20). The motor member (20) is an electric motor, and the mechanical means (22) of movement transmission are mounted inside the body (18) between the electric motor (20) and the drive member (24) to drive the said drive member (24) from the electric motor (20). The transmission means (22) comprise means (26) of mechanical disengagement of the electric motor (20) from the drive member (24), which, after disengagement, allow the drive member (24) to be moved independently of the electric motor (20).
