Some Boeing 737 Rudders at Risk of Jamming, NTSB Warns.

The US National Transportation Safety Board (NTSB) has issued a warning about a faulty component in some Boeing 737 aircraft that could cause the rudder control system to jam. The issue affects about 350 parts supplied by Collins Aerospace, a unit of RTX Corp., for certain 737 Max and 737 NG aircraft. The NTSB has made urgent safety recommendations to the US Federal Aviation Administration (FAA) and Boeing to address the problem. The FAA has stated that United Airlines is the only US airline that had the affected parts, but it is no longer using them. The flaw was discovered during an investigation of an incident in which rudder pedals on a United Airlines 737 Max 8 got stuck during landing. The NTSB has recommended that Boeing examine its procedures for pilots encountering similar scenarios and that the FAA determine whether the faulty parts should be removed from planes. Boeing is working with its supplier to address the issue and ensure appropriate operating procedures for flight crews. The FAA has accepted the NTSB's recommendation and will convene a review board to determine next steps. [Extracted from the article]
