What is a common failure mode for landing gear systems?

A common failure mode for landing gear systems is hydraulic system failure. The landing gear operates primarily through hydraulic mechanisms, which provide the force needed to extend or retract the gear. If there is a failure in the hydraulic system—such as a leak, loss of fluid, or pump malfunction—it can directly impact the operation of the landing gear. This could prevent the gear from deploying or retracting properly, creating a serious safety concern during takeoff or landing.

The hydraulic system is crucial because it generates the necessary pressure to operate various components of the landing gear. Issues such as air in the hydraulic lines, contaminated fluid, or defective hydraulic components can compromise the functionality of the landing gear, leading to potential emergency situations.

Understanding how hydraulic systems integrated with landing gear can fail helps in grasping the importance of routine maintenance and monitoring hydraulic fluid levels and conditions to ensure safe aircraft operations.
