On 7 June 2021 an Embraer ERJ170 had just commenced its descent towards destination when both primary and secondary pitch trim systems failed resulting in excessive nose-down pitch control forces and an inoperative autopilot. The flight was completed without further event with the Pilot Flying using both hands on the control yoke to control pitch attitude manually. During the landing roll the nosewhweel steering system also failed. The pitch trim failure was attributed to probable jamming of the trim actuator due to water, possibly condensation, freezing within it. The steering system fault was attributed to a completely unrelated sensor failure.
