A method is provided. The method includes, after a landing of an aircraft, detecting by sensors the position of the landing gear at a first sampling frequency, while the position of the landing gear is detected as vertical. After detection of a horizontal position of the landing gear, detecting by the sensors the position of the landing gear at least at a second sampling frequency, while the position of the landing gear is detected as horizontal. After detection of a vertical position of the landing gear, acquiring by said sensors physical parameters relating to the ageing of the landing gear, and detecting a landing of the aircraft at a third sampling frequency until a predetermined period has expired. The third frequency is greater than the second frequency, which is greater than the first frequency. Measurements relating to the ageing are stored as a function of the measured physical parameters.
