What could be a potential sign of a rigging issue during flight?

A potential sign of a rigging issue during flight is unusual or unexpected control feedback. This feedback can manifest as a change in the way the aircraft responds to control inputs, indicating that the control surfaces may not be functioning correctly due to improper rigging. When an aircraft is rigged correctly, control surfaces should move smoothly and predictably in response to pilot inputs. If there's a problem with the rigging, it can lead to unexpected behavior, such as excessive play in the controls, unresponsiveness, or sensitivity that wasn’t present before. This unusual feedback serves as a crucial warning sign that something may be amiss, prompting further investigation to ensure safe operation.
