Abstract
A method for checking the tightening tension of at least one fastening bolt for fastening at least two aeronautical parts, wherein it includes the steps of mounting a centering device on a head of a screw of the bolt, the centering device including an aperture aligned with an axis of the screw; engaging one end of a sensor in the aperture of the device until this end is in contact with the head of the screw; checking at least one physical parameter of the bolt by the sensor, this parameter being representative of the tightening tension of the bolt; then removing the centering device.
Claims9
A method for checking a tightening tension of at least one fastening bolt for fastening at least two aeronautical parts, wherein the method comprises the steps of:
- a) mounting a centering device on a head of a screw of the bolt, the centering device comprising a first axial orifice aligned with an axis of the screw;
- b) applying a coupling liquid to the head of the screw;
- c) engaging one end of a sensor in the first axial orifice of the device until said one end contacts the head of the screw, and evacuating an excess of the coupling liquid through a second transverse orifice of the device, said second transverse orifice opening into said first axial orifice;
- d) checking at least one physical parameter of the bolt by means of said sensor, said parameter being representative of the tightening tension of the bolt;
- then
- e) removing the centering device.
