What should be done if unusual control feedback is noticed?

When unusual control feedback is noticed, it is crucial to investigate for potential rigging issues because such feedback can indicate underlying problems that may affect the aircraft's handling and safety. Rigging refers to the setup and alignment of control surfaces and their associated systems. If there are discrepancies in how the control surfaces respond or feedback feels abnormal, it often points to misalignments, excessive play, or structural problems that need to be addressed immediately.

Addressing rigging issues ensures that the control surfaces function as intended, which maintains the aircraft's stability and controllability. Ignoring unusual feedback can lead to more severe complications during flight, and continuing without investigation may increase the risk of failure in critical control systems. Hence, investigating potential rigging issues is not only a necessary precaution but a fundamental principle of maintaining aircraft safety and airworthiness.
