Than 60 years ago in the korean war on al jazeera. Thats like that but it gets noticed and it is tended in. As and in the good as less of a kindly look at than to send. Food at the look at granny has. Never gave up with the good in a better book would you like me to get it that i should be here without being obvious that ive been delegated is that i you i dont what it was that i had been. A march 10th 2019 a plane carrying a 157 people crash in this field in ethiopia about it to kilometers from the capital of addis ababa and send a crew it up for you i passed just as crushed shelled out to take debris and lost still linger to this comes to the families of those that lost loved ones it is the same type of the plane was a boeing 737 max 81. 00 of the american manufacturers newest model says it was the 2nd 737 next to crash in less than 5 months left a month ago. Weve never seen 2 reporters catastrophic were destroyed with passengers on board sorely in the service now. And in the aftermath families and investigators are still searching for answers. Fault lines traces what led to the 2 crashes when asked if american aviation regulators have allowed industry too much control over safety. The last time boy you spoke to supply fell submit it was a sunday morning. It was a Flight Attendant for ethiopian airlines. She was going to work on a flight to nairobi and then returned to addis ababa that day. Look so happy and weve been waiting for months on. End the morning she didnt even wake me up because my son and i were like. I almost had my child and she dont want to wake us you know she just. She told me later when she called me she to call she once told me when she come back. And. Its a critical. And before she on board. She called me. And she told me that she wants to have lunch with me so i should pick her up and i said ok well do that you know its sunday i got nothing to do so ill do that. But she wanted to come up. Sooner and conduct. A few hours after he last spoke to his wife oh you got a call from a friend asking if he had heard about a plane crash not far from the capitol. He went straight to the airport. I dont even know how to drive you know like im shaking. So this friend of mine he took me to the airport. And we start asking people whether they know something about it or not like and nobody knows anything but everybodys crying like then we waited for several hours and i do end of the day they told us that there is no survive. The chaos and pain from that day have not had. And there have been few answers for family members like by you since the crash. The line. I mean she was there with. You was very humble. Very humble. Loving caring. And my my basis for it. Thats what. After the crash it was too painful to stay in the home he and also about lived in. So we moved in with her parents through that. I couldnt go there. I just couldnt. She learned over the place you know. We paint the house together with a leg of the couch together myth really everything in that house i remind me how far in the lake. Was the lead of it. When you lost that. All your focus will be on the things that give you a little bit closer i want you to know what you lost so thats what im trying to find to get close. To closure as far away. Less than 5 months before the ethiopian flight went down a boeing 737 max crashed off the coast of indonesia killing all 189 people on board. But it was only in the aftermath of the ethiopian flight that aviation authorities around the globe grounded the 737. 00 max. These are just a few of the 737. 00 maxes that are grounded around the world while investigations into the crashes and the design of the aircraft continue. Some details have emerged bit by bit about what could have caused the planes in indonesia and ethiopia to go down. Software the control the tail of the plane has been implicated in both crashes. But to understand the full story it means tracing the history of the boeing 737. 00 max. In many ways. 737. 00 max was born out of competition. We come to the pearce air show. This is the largest air show in the world. And a chance for the Aerospace Industry and play makers to celebrate their latest creations and commercial sales. It was here in 2011 that boeings rival european manufacturer broke records with orders for their new plane a 320 meo really isnt a story announcement bizarre just ever order for a free to any family so we talk about the space where we basically fly every day on the domestic flights and smaller short during the continent flights and boeing and airbus dominates that 100 percent airbus a 320. 00 neo was an upgrade of an older model but with a new fuel efficient engine promising savings to airlines and pitching boeing offguard the fact that decided to reengineer which is of course much quicker than doing a new aircraft put boeing into a decision do we stay with the plan to make a new way or do we actually go and also re on to an r. And d. Platform 737 into that for. Facing the loss of borders to airbus to large clients Like American Airlines boeing decided not to make a new airplane to compete with their bus and instead decided to upgrade the work course of their fleet to the 7 37. 00 so this is the empty bottle yes this is the model that the macs were built on this is the geoffrey vs model what would be different about this model it would be sensibly larger and youre getting a little bit more. One of the Key Selling Points of the max to airlines was that it was just like 730 sevens their pilots were already certified for so they wouldnt need expensive training in a flight simulator. The max was certified by american aviation authorities in 2017 and became the wastebaskets selling plane if you own an airline and i said i have a new airplane for you its very similar to the other airplane and heres the price tag your response maybe you havent seen or a plane ive got to train my pilot simulators in a more expensive venture well heres the goodness you dont have to train a menace given this little i pad course they can do it at starbucks the same jet to worry about can you get the f. A. A. To certify it that way. Absolutely and theyre off to the races well. 37 x. 2 for straight the training was straightforward on an i pad like this meters the new variants include an extended nose gear they even see a family they seem to be fighting you with a lot of ancillary information they dont seem to be fearful of inundating but it didnt mention software in the macs that authorities now believe played a role in the 2 crashes and you see what says flight controls right there is where you would likely have them cast if you were going to discuss and nothing totally absent. On october 29th 2018 the 1st 737 max crashed it was an air flight in the wind down off the coast of indonesia what happened was that the aircraft behaved very strange for the pilot and he was trying to master this in my view he was more than average pilot and hes mastering all of the attack which we later learned was him comes. In cas is a system that boeing put on the max to counter extreme situations that could occur due to the new larger engines. In both the indonesian and ethiopian flights the system kicked in when it shouldnt have. He didnt know about the fact that there was a system which was actually meant to never be activated its a system which is. Basically there to help you it is a very grave emergency that this was triggering and he mastered that unfortunately and he handed over to his 1st officer to try to understand whats was happening and he told him what to do the 1st officer wasnt prepared to the aggressiveness of the system they were fighting. The pilots on the indonesian flight thought him cast more than 20 times before the plane went down 12 minutes after takeoff. In cas kicked in forcing the nose down thinking it was higher than it really was due to faulty data from just one sensor called an angle of attack sensor. A few weeks after the crash in indonesia boeing executives met with the union for American Airlines pilots to discuss the software. In this very building boeing came in on november 27th and we question. I have been the one asking the question how could you have designed a single point of failure and they quickly came back with us not the back of his you. And how responsive but we dont even know the system existed how can we be the backup for something that we dont even know exists. After the crash in indonesia but when the f. A. A. Issued a directive to 737 pilots around the world to use a known emergency checklist if in cas kicked in when it shouldnt. According to investigators the ethiopian Airlines Pilots fumbled that but it still didnt save them. The forces were too bright they were too on balance in the train system that they could then get out of that seat and in my view the a model to check at least it wasnt enough it should have mention things that call it the if youll be in crew update. Its not just the ethiopian Airlines Pilots though since the crash other pilots have replicated the conditions of the ethiopian flight in simulators like this. And some havent been able to recover the plane using just the checklist. Its already been demonstrated by or very own fleet manager pilots that this aircraft impossible to trim and surf like additions big difference from the very well you may want to take an umbrella today looks like it could rain to there is a tsunami theres a hurricane theres a tornado. Multiple investigations have been launched including a criminal probe by the department of justice to figure out what went wrong during the design and testing of the 737. 00 max. But a former boeing engineers who worked on the plane says it took place amid immense commercial pressure. Can you talk to me about the environment while designing the macs cost pressure and time time pressure was the biggest. He spoke to us on the condition of anonymity due to fear of repercussions from boeing for speaking out or believed we had customers the would be in. For most that if they couldnt get the airport soon enough they would go to an airbus solution to their mortgage. So commence pressure on during the airplane to more as soon as possible he says there was a pressure to keep the plane to the same regulatory requirements of the previous 737 model. When you build an airplane based off of another reporting differences and 2 additional training on the 737 minutes there is quantum pressure to change anything from a cost perspective change costs money. And the business started drives the culture. What creates the cost of schedule pressures is a constant pursuit of the bottom line by the leaders of the company and the leaders of the company of the board and there was that all worked at boeing for 3 decades until 2014 and then worked at the union that represents boeing engineers before retiring the summer. He didnt work on the macs but says that during his time at boeing changes that the corporate level led to shifts in the companys Safety Culture boeing is looking to cut costs on both the top and the bottom of the of the problem youve got to move labor to places where it doesnt cost as much to pay and then theyre going to cut their production costs and look for cuts and all their designs to reduce the costs so that number one concern for their upper management is return on a bus when youre a solo. Target on return investment because youre your business company. And even have taken safety for granted. Details of the maxs safety analysis by boeing are still coming out. But some things have emerged in the aftermath of the crashes. Boeing safety analysis didnt test for what could happen if impasse was triggered by a broken or faulty sensor. Its also not clear if the company considered the impact of the software triggering more than once. Boeing declined an interview with us but in a statement said theyre focused on quote working with Global Regulators on testing and implementing the software update. But at the end of the day in the system the supposed to ensure our safety in the air the final approval wasnt going. It was the federal Aviation Administration f. A. A. The Government Agency responsible for certification of airports we learned their fate never performed its own assessments of the system in fact that had delegated much of its oversight to the boeing company. This was a complex point ok now im new engines on you dont lot of Different Things with the Software System that wasnt even mentioned in the pilots manual how did the f. A. A. Come to the conclusion that it was appropriate. To certify an anti stall Software System the m cas that not only drew data from a sensor that had a history of problems but also that didnt have or does in addition to federal probes since the crashes f. A. A. Officials have been called to testify before congressional committees asking if the agency deferred too much to boeing for the plane safety analysis the f. A. A. Welcomes scrutiny that helps make us better as you all know the f. A. A. Grounded the u. S. 737. 00 max fleet on march 13th 2019 that decision was based upon crash site findings and satellite data that together indicated some similarities between the ethiopian and indonesian accidents that warranted further investigation of the possibility of a shared car. In recent Years Congress and the f. A. A. Have delegated more safety certification to manufacturers like boeing and outsourcing of sorts in fact last year 96 percent of boeing sort of occasion was delegated to the company. Supporters of the system say that private Companies Know the latest Technology Better than government workers and that the f. A. A. Isnt staff to do the work themselves the system the delegates authority outside the walls of the f. A. A. Is a system that can work and ive seen it work. And i believe in whether its executed appropriately is obviously on the question theyve taken it as weve said for over a decade way too far too fast for Michael Pearl and the president of the union that represents f. A. A. Inspectors agrees that the f. A. A. Needs to be staffed better for oversight the point is they have to have enough inspectors to oversee and regulate the industry the industry has the expertise the industry wants to continue to expand thats fine but they have to have enough regulatory ability in the f. A. A. To oversee that that is occurring but the union is also concerned that the industry and the f. A. A. Are too close there are people that came from industry that are working in the f. A. A. As people and you have a management that want to go back in history right now industry is driving the f. A. A. Industry also says i want to get this airplane out by this date or i want to get this signed off by this date. One of the questions facing various investigators now is if and how much that pressure impacted the certification of the 737 max is a highly challenging products to make and services to provide so that mistakes get made the question is do you have enough level of backup and thats for obviously what didnt happen there wasnt enough backup either in the decisions i ever made on designs that were were put out there. As investigations continue into the crashes f. A. A. Officials now have to account for how the agencys oversight system failed and the certification of the maps we asked the question and the f. A. A. Told us the answers to the question did you test the m. Cas misfire like happened with with lion aaron ethiopia and they asked in the initial certification no we did not and they went on to say that we didnt because the boeing corporation told us it was so transparent to the pilot that there was no need to test a misfire presentation. And what was even more horrid to hear was the f. A. A. Said so we didnt. Thats not oversight what were the steps the f. A. A. Took in reviewing the m. Caste system and the accompanying train. Because ive asked it now 3 times and i have it be blunt with you sir with all due respect i havent gotten a direct answer we will get that answer freezer well most engaged in this system throughout the process in detail dont worry about boring me we need to understand that because theres a critical component of this i can write can assure you that the system was examined and certified because it was a new system to the max it was and we retained it and we we had the oversight of that and we certified mr owen with aljazeera once were investigating this. Why didnt the f. A. A. Catch the problems with always and caste system i mean i think the body of the hearing just now should answer any and all of. The f. A. A. Declined an interview but in a statement said the Agency Certification process has quote consistently produce a fair craft decides its been clear the system failed. Thats the 1st step to repairing the system the systems failed the systems boeing the f. A. A. Other oversight areas from within those groups it failed whats the measure on that judgment hes 2 crashes its that simple the system failed it failed our passengers it failed glow. The f. A. A. Is currently testing fixes boeing has proposed to the plane. Its not clear when the 737 max be back in the air. And what it would take for passengers to trust it again. The system of regulations and oversight could almost fill. If it werent for whats at stake. And hundreds of other families would know that too well. Who is he like as a mom. Shes the best mom you ever see. Of her kid very much. How are you. You know thats what scares me the most. When of course i know how she used to care for her child and. When i beat up father you know for him. Was able to do both things like a mom and dad. Its not going to make any difference what i am and we are matters that nobody cares about. But this one is a no like bigger than me what were talking about its not about me its about everybody. We might dont have any power again its boring. F. A. Or something but as a human being. You know you dont let things like this to happen in all the time get away with. It and here. Didnt the u. S.
