Boeing is facing a fresh investigation over another 737 Max flaw after a plane's rudder got stuck during landing
A United Airlines 737 Max 8 experienced "stuck" rudder pedals while landing, the NTSB said in its preliminary report. The investigation is ongoing.
Yep, one crash at Colorado Springs had a 737 fly full speed into the ground, others very similar.. 😢
What does the rudder have to do with a 737 flying full speed into the ground. Rudder is the yaw of the aircraft…if the rudder is stuck on landing, then that would say with a crosswind landing the pilot was inputting opposite rudder of the aileron and it got stuck so the nose kept skewing to the rudder input side.
Jet aircraft use swept back wings for high speeds at high altitude. They are not very effective at low airspeeds (takeoff and landing) and high angles of attack (takeoff or go-around.). If a rudder goes full scale to one side at a slow airspeed, it could very well render the ailerons ineffective. I know someone that crashed in training by pressing the wrong rudder on a simulated engine failure on takeoff and that happened. I actually wanted to try it myself in the simulator and I crashed too… the aircraft slowly banks and descends and it is uncontrollable unless you release the rudder. Note : not sure how they are defining “full speed into the ground.” Forward speed or vertical speed… or both?
Edit : just read the article…rudder locked neutral after landing so they couldn't steer on the ground. If it locked neutral in the air, not a big deal, but landing in a crosswind would be difficult if not impossible.
