The Tiny Cable That Almost Crashed A Passenger Jet

This is the story of Republic airways flight 4439, America is a strange country when it comes to aviation, it has rules that in other countries would just be weird. For instance the mainline the regional airlines often take on the branding of their larger full service brothers and operate low demand routes to far flung parts of the country but the most interesting thing about all of this is the size of the jets that these regional airlines are allowed to operate. The scope clause limits the size of these jets to 86000 pounds. This is why republic airways was operating this flight from Atlanta to well the report doesn’t really say where the flight was headed to but it just said that the incident happened near Atlanta. But other sources that i have consulted said that the flight was headed to LaGuardia. So that’s what were going with although I wonder why a flight to New York from Atlanta of all places had 6 places on board, if you have any idea about this please do let me know. The jet lined up with runway 9L at Atlanta and the pilots pushed the engines to max power and they were rolling down the runway. Within moments they were airborne as flight 4439 left Atlanta behind and gained in altitude the pilots decided that they were going to now engage the autopilot but for some weird reason the autopilot would not come on. But that wasn’t all the pilots figured out that they were having some control issues with the plane, it was pitching up much more than they expected the plane to. It was as if the plane had a mind of its own. The pilots immediately knew that they had a pitch trim runway. Now what is trim? Trim is basically a way for the pilots to automatically adjust the control Surafces on the plane so that the pilot does not have to constantly provide a control input. For example take a situation where one of your engines flames out, the plane now wants to yaw, in this case you can trim the rudder to counteract this yaw. In the case of republic airways 4439 this trim system seemed to have a mind of its own pushing the nose of the plane up. When this happens it’s known as a pitch trim runaway. If you paid attention to the max crisis this is what a lot of the pilots thought they were dealing with. Obviously pilots are trained to handle this and in the captains training kicked in and he held the trim disconnect button down on his side. Theoretically this should tell the trim system to knock it off but the the plane still wanted to pitch up, the captain asked his first officer to try the pitch disconnect from his side but still there was nothing the plane wanted to pitch up and the pilots struggled to keep the nose down. The pilots knew that they were in deep trouble and immediately declared an emergency letting the controllers know that they had a trim runaway. These pilots needed to land asap and the controllers offered up runway 10 for them and they decided to go for it. The situation in the cockpit was so bad that both pilots were pushing down on the yoke meaning that neither of them could get to the quick reference handbook to trouble shoot the issues, their only line of defense was their wits and experience. The tower then asked if they needed to go higher to trouble shoot this problem and then the seconds ticked by then the transmission came in “Brickayrd 4439 were in a stalling situation”. The pilots were quite literally figfhting for their life with the plane that just did not respond to their commands. ATC now knows that what ever is happening with flight 4439 is serious and they they start cleaning the airspace around runway 10 out. Just so that they can give flight 4439 a straight in approach should they need that. They also stop departures to give the E175 some manevering room and to prevent a potential collision should the 175 lose control. As all of this is happening the piots in the cockpit are trying to descend but they still did not have any luck. The pilots now having gotten some control of their plane back ask whats available, the controllers let them know that runway 10 was all theirs and they were more than willing to get anybody and everybody out of the way to make any
