The horizontal stabilizer — which trims the aircraft's nose up or down to hold level flight — began moving on its own, a condition known as a trim runaway. Left unchecked, it can steadily push an aircraft's nose in a direction the pilots don't want, forcing them to fight the controls to hold their intended flight path. The crew declared a mayday and told air traffic control they needed to return to O'Hare immediately.

Controllers cleared the flight back in ahead of other traffic, and the crew worked the malfunction using their emergency procedures for runaway stabilizer trim — checklists built for exactly this situation, which typically call for isolating the trim system and flying the aircraft manually. The CRJ landed safely back at O'Hare.
