Government Agency Issues Urgent Safety Warning on Faulty Boeing 737 Rudder System

The National Transportation Safety Board (NTSB) issued urgent safety recommendations to aircraft manufacturer Boeing and the Federal Aviation Administration (FAA) regarding a “significantly compromised” critical flight control component on some 737 airplanes.
Upon testing one of the rudder control components—a rollout guidance actuator—from the incident airplane along with an identical unit from another airplane, NTSB investigators found that the components’ functioning was “significantly compromised” when tested in a cold environment.
The component was manufactured by Collins Aerospace, a North Carolina-based company that is one of the world’s largest suppliers of aerospace and defense products.
Installed in the tail of some B-737NG and 737 MAX airplanes, the rudder controls rotation along an aircraft’s vertical axis and is a primary flight control mechanism. It is not used to steer the direction of flight but rather to control adverse movements.
When jammed, pilots are instructed to use maximum force, “a combined effort of both pilots,” to overpower the restricted rudder, according to the NTSB. The report expressed concern that such an amount of force applied during landing or rollout “could unintentionally cause loss of control or departure from a runway.”
The NTSB recommended that Boeing notify pilots of the potential jamming of rudder control systems due to moisture. The agency asked the FAA to determine whether the affected actuators should be removed and to notify aviation regulators in other countries.
The FAA acknowledged the issue in an emailed statement to The Epoch Times, saying the agency “accepts this recommendation from the NTSB.”
“As a party to the investigation, the agency has been monitoring this situation closely,” the statement reads.
The FAA said it will soon “convene a corrective action review board based upon the NTSB’s interim recommendations and determine next steps.”
“Additional losses were calculated this week for Boeing suppliers, who lose $144 million, and non-Boeing Seattle workers impacted by the strike, who lose an estimated $25 million,” the report said, adding that the disruption has shut down most of the company’s commercial airplane production.
The FAA has capped Boeing plane production volumes following the incident.
The Epoch Times contacted Boeing and Collins Aerospace for comment regarding the NTSB report but had not received a response by publication time.
