WASHINGTON (Sept. 26, 2024) — The National Transportation Safety Board Thursday issued urgent safety recommendations to The Boeing Company and the Federal Aviation Administration in response to the potential for a jammed or restricted rudder control system on some 737 airplanes.
The NTSB is investigating a Feb. 6, 2024, incident in which the rudder pedals on a United Airlines Boeing 737-8, a MAX variant, were “stuck” in their neutral position during the landing rollout at Newark Liberty International Airport, Newark, New Jersey. The captain used the nosewheel steering tiller to control the airplane’s direction after touching down. There was no damage to the airplane or injuries to the 155 passengers and six crewmembers. A preliminary report detailing the circumstances of the event was published on March 12.
NTSB investigators tested one of the rudder control components from the incident airplane, a rollout guidance actuator, at the component’s manufacturer, Collins Aerospace. When the incident actuator and an identical unit from another airplane were tested in a cold environment, the actuators’ function was significantly compromised.
