Zusammenfassung:	The invention relates to a spray device for washing a gas turbine engine of an aircraft having an engine shaft and an inlet cowling. The spray device (33) comprises a central axis (501), a central body (50), and at least one pipe (61) having at least one nozzle (54) adapted to inject liquid into said gas turbine engine during a washing operation. The spray device is adapted to be positioned in a washing operation position relative an inlet of said gas turbine engine without contact between the at least one pipe (61) and the inlet cowling. When the spray device is in the washing operation position, the central axis (501) is substantially aligned with the engine shaft.
