Which consequence results when a jet aircraft's elevator-trim-tab servo motor fails?

💡 Explanation

Loss of control loading occurs because the elevator trim utilizes a servo motor; its failure could cause a *servomechanism runaway*, resulting in amplified and uncommanded control-surface inputs; therefore, a hazardous over-control results, rather than any engine or autopilot failure.
