Abstract: A multifunction device for an undercarriage, the device comprising at least a first shaft rotatably mounted on the aircraft to rotate about an axis of rotation that is substantially parallel to a hinge axis hinging the undercarriage to the aircraft, a telescopic second shaft rotatably mounted in the undercarriage and extending down along the undercarriage to the proximity of wheels carried thereby, and motor means adapted to cause the first shaft to rotate. The telescopic second shaft is a single shaft and it extends inside the undercarriage to the proximity of an axle carrying the wheels of the undercarriage, being connected to a differential connected to the wheels via drive shafts extending inside the axle.
