![]() ![]() When the aircraft’s computer sensed that the plane was in danger of a stall, MCAS worked by triggering the horizontal stabilizer located on the aircraft’s tail to push the nose back down. “The idea was to provide something that would offset that pitching moment, or causing the nose to come back up.” “The aircraft starts to want to pitch up all by itself,” said Peter Lemme, a former Boeing engineer, who didn’t work on the MAX design, and now serves as chief consultant for Seamless Air Alliance. The software, called Maneuvering Characteristics Augmentation System (MCAS), was added to compensate for the larger, more powerful engines that had been added onto the existing 737 airframes, which changed the in-air flight characteristics of the aircraft. He said investigators were surprised to learn that Boeing had installed a flight control software program that could force the plane into a dive without the pilots’ knowledge. Nurcahyo said the NTSC asked Boeing about the kind of system on the 737 MAX that could have caused it to behave in such a manner. “I knew that the pilot was fighting with the plane.” “I never knew … any case of the aircraft that fly down and up and up and down like this,” Nurcahyo said. The flight data recorder from Lion Air 610 revealed that the plane had gone out of control - it had moved up and down over 24 times before it finally dove into the sea at full speed. The 737 MAX’s flawed flight control software Nurcahyo Utomo, senior safety investigator of the NTSC. “The pilot reported that he had a problem with the speed and altitude indicated on captain’s side,” said Capt. However, according to the NTSC, the crew left incomplete notes about the details of the emergency. ![]() ![]() A third pilot who just happened to be in the cockpit was able to help the two pilots resolve the situation and the plane landed safely in Jakarta. The aircraft nosedived four times as the pilots struggled to regain control, according to Indonesia’s National Transportation Safety Committee (NTSC). “To be honest, I think it’s almost like my last flight and this is my last day.” “All of us were screaming like we are in a roller coaster,” said Rakhmat Robbi, a passenger on the flight. 28, 2018, Lion Air Flight 610 from Bali to Jakarta experienced an in-flight emergency as the plane suddenly began to nosedive after take-off. And after its first flight in May 2017, the 737 MAX 8 went 17 months without incident. Indonesia-based budget airline Lion Air was one of Boeing’s biggest buyers, ordering over 200 Boeing 737 MAX 8s at a cost of $22 billion. “You can sit at Starbucks sit at home, and it would ask you a couple of questions to affirm the learning.” Dennis Tajer, an American Airlines pilot and spokesperson for the Allied Pilots Association. “It went through a robotic voice describing what the MAX is about,” said Capt. Instead, Boeing said pilots could get up to speed on the new model by reviewing a 56-minute online course. The 737 MAX was a revamped version of Boeing’s highly popular 737 aircraft, with added power and fuel-efficient engines.īoeing touted the MAX as being so similar to the previous model of the 737 that it said pilots wouldn’t be required to undergo any training for it in a flight simulator - a costly expense for airlines. The plane that crashed on that clear, sunny morning in Ethiopia was a Boeing 737 MAX 8, a new model that had become the fastest-selling plane in Boeing's history. "People shouldn't innocently buy an airplane ticket and then be in a flying coffin,” she said. Nadia Milleron’s daughter Samya Stumo, 24, died in the Ethiopian Airlines Flight 302 crash in March 2019. “On the BBC at 3:00 in the morning, it said that a plane, Ethiopian Airlines taking off from Addis Ababa, had crashed,” said Stumo’s mother Nadia Milleron. Everyone on board, including Stumo, was dead. Just six minutes after takeoff, ETH302 dove at full speed into a field 30 miles away from Bole International, near the town of Bishoftu. Others, she said, “were going to volunteer and do good for the world.” Some were heading to Nairobi for a United Nations conference, according to Ethiopian journalist Hadra Ahmed. After a two-hour layover, Stumo was scheduled to move on to Nairobi, Kenya, on Ethiopian Airlines Flight 302.Īlong with her were 148 other passengers from 35 different countries. The 24-year-old, who had been raised on a Massachusetts farm, was on her first overseas assignment for the global health care group, Thinkwell. Samya Stumo arrived at Bole International Airport in Addis Ababa, Ethiopia, on the morning of March 10, 2019, after a long flight from Washington, D.C.
