The invention discloses a coating assembly of an aircraft pipeline and a bleed air leakage detection device. Comprising a supporting layer (1), an optical fiber sensor (2) and a coating layer (3), the supporting layer (1) wraps the periphery of an aircraft pipeline, a cavity (10) is formed between the supporting layer (1) and the outer wall of the aircraft pipeline, the outer surface of the supporting layer (1) is wrapped by the wrapping layer (3), the optical fiber sensor (2) is embedded between the supporting layer (1) and the wrapping layer (3), and more than one optical fiber grating sensor (23) is distributed on the optical fiber sensor (2). The leakage position point of the air entraining pipeline can be accurately judged.
