FAA Investigates Serious 737 Rudder Issues at Boeing, Potential Global Risk

arlington - The FAA is looking into a defective component in some 737 aircraft that could cause the tail rudder to jam. United Airlines is the only US carrier affected. Dutch airlines KLM and Transavia have stated the issue does not impact their 737 NG planes.

The American transport regulator NTSB warns of a faulty part in certain 737 aircraft, potentially leading to the tail rudder getting stuck. FAA states that United Airlines is the sole American carrier affected by the defect, with unclear implications outside the US. In the Netherlands, KLM and Transavia operate 737 NG aircraft, but both airlines confirm the problematic component is not installed in their planes.

The parts in question were supplied by US supplier Collins Aerospace for some 737 MAX and 737 NG aircraft. According to NTSB, the part was incorrectly assembled, making it more susceptible to moisture and freezing. This could restrict the movement of the rudder system. The defect came to light during an investigation into an incident on February 6, where the rudder of a United Airlines 737 MAX 8 became jammed during landing. The plane managed to land safely with no injuries reported.

FAA will address the findings, and NTSB has requested the aviation regulator to inform foreign aviation authorities in case removal of the parts becomes necessary. This adds to Boeing's list of setbacks, as the company is already dealing with quality control scandals. Earlier this year, a door panel detached from an Alaska Airlines Boeing 737 MAX 9 due to missing bolts. Critical reports on quality checks for other planes led the US regulator to mandate Boeing to implement an improvement plan.
