United Airlines pilots said pedals that control rudder movement on the plane were stuck as they tried to keep the plane in the center of the runway during the Feb. 6 landing.

The pilots were able to use a small nose-gear steering wheel to veer from the runway to a high-speed turnoff. The rudder pedals began working again as the pilots taxied to the gate with 155 passengers and six crew members on the flight from Nassau, Bahamas, according to a preliminary report by the National Transportation Safety Board.

Boeing said this is the only rudder-response issue reported on a Max, although two similar incidents happened in 2019 with an earlier model of the 737 called NG or next generation, which has the same rudder-pedal system.

The manufacturer said the issue was fixed by replacing three parts. The plane has made dozens of passenger-carrying flights since then, according to data from FlightAware.

    when I was a kid, my dad worked at Lockheed… they had the coolest Take your Kid to Work Day. The basement was where the fun was- specifically the prototype testing lab with the 50 pound hammer that they were constantly knocking around mock ups of computer cabinets, the ginormous vibration table, and, yes, a cubical-sized refrigerator to do just that. The sound isolating chamber was also kinda cool… and spec sheets of the x33 demonstrator.

      Thinking back on what I worked with, it was far more impressive than I realized at the time. We had 15 foot custom cables to connect the 125+ pin flight computer (four of them) to our test system. The test system also controlled the environment chamber, which had like 90 minute cycles from -70C to 50C but it also had a vibration table that has incredible acceleration. I believe it could reach near vacuum, and pressurize, I don’t remember how much.
