What maintenance procedure involves inspecting exposed pistons for damage?

Inspecting shock struts involves assessing the condition of the shock absorbers, which are crucial components in an aircraft’s landing gear. This procedure specifically includes examining exposed pistons for signs of damage such as dents, scratches, or any signs of wear that could compromise the functionality and safety of the shock strut. The pistons are integral to the operation of the struts, as they help absorb and dampen the shocks and stresses experienced during landing and takeoff. Proper inspection ensures that these components are functioning effectively, contributing to the overall safety and performance of the aircraft.

Other procedures mentioned, like tire rotation, fluid level checking, and bearing lubrication, do not directly involve the inspection of exposed pistons. Tire rotation is focused on the tires themselves, fluid level checking pertains to the various fluids within the aircraft systems, and bearing lubrication addresses the maintenance of moving components but does not include inspecting shock struts or their pistons.
