Proper servicing of landing gear is obviously important to ensure proper landing gear operations during takeoff and landing. It is equally important to ensure proper retraction and extension to prevent potential interference with other aircraft systems in the case of abnormal landing gear conditions.
If the landing gear servicing tasks are not properly performed, issues can occur such as struts seized in a retracted position and strong vibrations that can affect the function of avionics equipment.
This article provides a description of best practices that maintenance crew can apply when performing the landing gear servicing tasks, with a focus on the shock absorber and the importance of regular lubrication.
