A recent incident involving a United Airlines 737 MAX landing in Newark highlighted a potential issue with the rudder system, as the pilot experienced stuck pedals upon touchdown. Although the incident did not pose a serious threat, it raised concerns about the safety of the aircraft. Further investigation by the National Transportation Safety Board (NTSB) suggested that cold temperatures may have played a role in affecting the mechanism that moves the rudder.
Boeing, the manufacturer of the 737 MAX, addressed the issue by replacing three parts of the rudder system, allowing the aircraft to return to service. Aviation experts emphasized the importance of maintaining a functioning rudder to ensure safety, especially in critical situations such as engine failure or severe weather conditions. The NTSB is conducting additional tests to better understand the cause of the rudder failure and determine any necessary actions to prevent future incidents.
The NTSB investigation revealed that a key component of the rudder system, a servo motor made by Collins Aerospace, experienced restrictions in movement after being subjected to cold temperatures. Despite the rarity of such incidents, further examination of the rudder servo system is deemed essential to ensure the safety and reliability of the 737 aircraft models. Boeing and Collins Aerospace are cooperating with the NTSB in the investigation to identify and address any potential concerns with the rudder system.
