The invention discloses a lubricating maintenance device based on an aircraft and belongs to the technical field of applications of aircrafts. The lubricating maintenance device based on the aircraft comprises a vehicle, an aircraft body, a steering engine linkage group and an oiling device. The vehicle comprises a control station and a vehicle compartment. The aircraft body is arranged in the vehicle compartment. The control station controls the flight of the aircraft body and the oiling operation of the oiling device. The oiling device is connected with the aircraft body through the steering engine linkage group. The oiling position and the oiling angle of an oil nozzle can be adjusted by changing the posture of each steering engine in the steering engine linkage group. It is guaranteed that oiling operation is accurately and efficiently conducted through a mechanical arm and an observation mechanism. According to the lubricating maintenance device based on the aircraft, the oiling device is carried by the aircraft, oiling lubrication is conducted in the air, the limitation of a working environment is broken through, operation is easy, the safety is high, efficiency is high, and effective combination between the aircraft and the oiling device is achieved.
