Abstract

Procédé de détermination d’un défaut dans un revêtement recouvrant une pièce d’un aéronef et pièce d’aéronef recouverte de couches de revêtement L’invention concerne un procédé de détermination d’un défaut (140) dans un revêtement recouvrant une pièce (100) d’un aéronef, dans lequel ladite pièce est recouverte d’au moins une première couche de revêtement (120) comportant au moins un pigment luminescent produisant, sous une lumière d’un premier spectre, une première couleur et, sous une lumière d’un second spectre, une seconde couleur, distincte de la première couleur, ledit procédé comportant : une opération d’éclairage de la pièce d’aéronef (100), au moyen d’une lampe (200) émettant une lumière du second spectre, et une opération d’observation de ladite pièce d’aéronef (100) pour détecter si une portion de ladite pièce présente une couleur différente de l’ensemble de la pièce, correspondant à un défaut de revêtement. Figure à publier avec l’abrégé : Figure 2Method for determining a defect in a coating covering a part of an aircraft and part of an aircraft covered with coating layers The invention relates to a method for determining a defect (140) in a coating covering a part (100 ) of an aircraft, in which said part is covered with at least a first coating layer (120) comprising at least one luminescent pigment producing, under a light of a first spectrum, a first color and, under a light of a second spectrum, a second color, distinct from the first color, said method comprising: an operation of illuminating the aircraft part (100), by means of a lamp (200) emitting light of the second spectrum, and an observation operation of said aircraft part (100) to detect if a portion of said part has a different color from the whole of the part, corresponding to a coating defect.
