Abstract
A method for repairing a zone of a metal structural aircraft part having a protection defect in the vicinity of an orifice for receiving a fastener. There is a step of positioning an isolation element on the zone around the orifice, a step of applying a coat of paint to the zone, covering the isolation element, and a step of inserting a metal fastener into an orifice of the isolation element, prior to or following the step of applying the coat of paint. The metal of the fastener is in contact with the isolation element, itself in contact with the metal forming the aircraft structure.

A method for repairing a zone of a metal structural part of an aircraft having a protection defect, said zone of the structural part having a first orifice for receiving metal fastening means, said first orifice having a first diameter, said method for repairing comprising the steps of:
- sanding, during which paint in said zone of the structural aircraft part is sanded,
- positioning isolation means, during which isolation means are positioned on said sanded zone of the structural aircraft part around said first orifice, said isolation means comprising a second orifice having a second diameter substantially equal to the first diameter of the first orifice, said isolation means being positioned on said sanded zone of the structural aircraft part around the first orifice so that said first and second orifices are coaxial, and
- applying at least one coat of paint, during which a coat of primer paint is applied to the sanded zone of the structural aircraft part, said coat of primer paint being applied to said isolation means.
