Abstract: A roller unit for moving a slat of an aircraft wing is provided. The roller unit is adjustable in height and axial position to adjust a gap between an idle roller and a guide rail integral with the slat. The idle roller is carried by an eccentric pin having a stem portion with a threaded portion and an axially grooved end portion. A threaded annular element cooperates with the threaded portion of the stem portion to define a desired axial position of the idle roller. An anti-rotation annular element, coupled in an axially slidable manner with the grooved end portion of the stem portion, may be coupled with the threaded annular element to prevent rotation thereof on the threaded portion of the stem portion. The threaded annular element and the anti-rotation annular element are tightened together between a pair of nuts.

Abstract: A handle for opening and closing a door of an aircraft is provided. The handle has a base part lockable to a rotatable shaft of an opening mechanism of the door, a hand gripping part connected to the base part, and a hinge connecting the base part to the hand gripping part to allow relative rotation of the hand gripping part with respect to the base part about a first axis. At least one seat is integral with the base part and at least one seat is integral with the hand gripping part, the seats being adjacent and aligned along a second axis parallel to the first axis. A mechanical fuse element of constraint is received in the seats, such that by applying to the hand gripping part a bending stress around the hinge greater than a predetermined threshold, the mechanical fuse element of constraint shears between the seats.
