Zusammenfassung:	The invention relates to a method and device for inspecting the structural damage to the skin of an aircraft after a lightning strike, wherein the skin comprises a set of marks caused by the lightning strike, said marks including a visual damage (VD) and a structural damage (SD). The method comprises the following steps: for each mark, measuring the surface area of the paint that has been removed by the lightning strike; comparing the measured surface area with a surface area threshold value, wherein the threshold value relates to the structural damage (SD) of each mark. La présente invention concerne un procédé et un dispositif d'inspection des dommages structuraux causés au revêtement d'un aéronef après un impact de foudre, lequel revêtement comprend un ensemble de marques résultant dudit impact de foudre, lesquelles marques comprennent un dommage visuel (VD) et un dommage structural (SD). Le procédé comprend les étapes suivantes consistant à : - mesurer, sur chaque marque, la surface de peinture qui a été éliminée par l'impact de foudre, - comparer la surface mesurée à une valeur seuil de surface, laquelle valeur seuil est liée au dommage structural (SD) de chaque marque.
