Critical Safety Alert: NTSB Flags Potential Rudder Jam in Boeing 737 Aircraft Following United Airlines Incident
By David Shepardson
WASHINGTON (Multibagger) - In a significant safety advisory, the National Transportation Safety Board (NTSB) has flagged urgent concerns over the potential for a jammed rudder control system in some Boeing (NYSE: BA) 737 airplanes. This follows a February incident involving a United Airlines flight, which narrowly avoided disaster.
Incident Overview
The NTSB is currently investigating an alarming episode where the rudder pedals on a United Boeing 737 MAX 8 became "stuck" in the neutral position during a landing at Newark Airport. Thankfully, the incident resulted in no injuries to the 161 passengers and crew onboard.
United Airlines acted swiftly by removing the rudder control parts in question from the nine aircraft that had them. These planes were originally built for other airlines, adding another layer of complexity to the issue.
FAA's Immediate Response
The Federal Aviation Administration (FAA) has been closely monitoring the situation and announced plans to convene a corrective action review board. This board, meeting on Friday, will assess the NTSB's interim recommendations and determine the next steps to ensure flight safety.
The FAA has confirmed that United Airlines is the only U.S. operator using these specific components, and it believes they are no longer in service.
NTSB Recommendations and Detailed Analysis
The NTSB has recommended Boeing immediately notify flight crews about the potential for rudder control system jams due to moisture accumulation inside the actuators. They also urge Boeing to devise appropriate flight crew responses for such scenarios.
Additionally, the NTSB has called on the FAA to determine whether certain actuators produced by Collins Aerospace, a unit of RTX, should be removed from service. If deemed necessary, these components should be replaced before the aircraft are allowed back into operation. The FAA may also need to alert international aviation regulators about this issue.
Root Cause Identified
Collins Aerospace identified the root cause: a bearing incorrectly assembled during actuator production. This flaw has affected more than 353 actuators delivered to Boeing since February 2017. Both Boeing and RTX have yet to comment on the situation.
Breaking Down the Impact for Everyone
What Happened?
- A United Airlines Boeing 737 MAX 8 experienced a jammed rudder during landing.
- No injuries occurred, but the incident highlighted a serious safety risk.
Why Is This Important?
- The rudder helps control the aircraft's direction. If it jams, the plane's ability to maneuver is compromised, especially during critical phases like landing.
- This issue could potentially affect other airplanes if not addressed.
What Actions Are Being Taken?
- United Airlines removed the faulty parts from their aircraft.
- The FAA is reviewing NTSB's recommendations to decide on further actions.
- Boeing is urged to inform flight crews and develop new response protocols.
- The FAA may require the removal and replacement of certain actuators from Collins Aerospace.
How Does This Affect You?
- For travelers, ensuring aircraft safety directly impacts your well-being during flights.
- Investors in Boeing, United Airlines, or RTX should be aware of potential financial implications due to safety recalls and regulatory actions.
- Airline industry professionals should stay updated to implement any new safety measures promptly.
By understanding these details, the general public can better grasp the significance of such safety advisories and their potential ramifications on travel safety and financial markets.

In Summary
The NTSB's urgent recommendations stem from a critical safety issue involving Boeing 737 MAX 8 aircraft, specifically related to the rudder control system. Immediate actions by United Airlines and ongoing reviews by the FAA aim to mitigate risks. This situation underscores the importance of rigorous safety protocols and swift responses to mechanical anomalies, impacting both passenger safety and financial stability in the aviation sector.
