lion air flight 043

Pilots tried to correct this by pointing the nose higher, until the system pushed it down again. Photographer: Pradita Utama/DETIKCOM/AFP via Getty Images Other times, it prompts them to pull everything back in the name of cost-cutting.

But they were running out of options. This time, there was no third pilot to help the flight crew. At over 400 mph of airspeed, the airplane was already past its redline. But complete overhauls are rare: the 737 last received one in 1997, with the debut of the third-generation 737NG, while the A320 hadn’t been refreshed since its launch in 1988.

The plane was making a one-hour journey to the western city of Pangkal Pinang when it went down.The jet crashed following a request from the pilot for permission to turn back to the airport minutes after taking off from Jakarta.Investigators had previously revealed that the plane, on previous flights, had experienced technical problems related to airspeed and altitude readings.Therefore the "angle-of-attack" sensor, which contributes to those readings, had been changed the day before the crash. The story of the Max is ultimately the story of the Darwinian business cycle where mature companies like Boeing face constant threats from new products, new competitors, and the search for new growth. Following standard procedure, the captain reported the episode to the airline, and the airline… Instead, families received bags of soil from the surrounding fields. The airplane barely responded. It has no redundancy: it takes input from just one AoA sensor at a time. The committee's report itself, though, does not spell out that conclusion.

That didn’t work either. For four days, angry pilots and airline officials bombarded Boeing with demands for more information. “The 737 was conceived in the 1960s as what today we would call a regional jet, and with every variant, they’ve pushed and pushed the thing to the end of its envelope,” says Patrick Smith, an airline pilot and blogger at At the same time, the designers couldn’t update it This allows airlines with common-type fleets to more easily substitute pilots and airplanes, making their operations more flexible. The airline, which also operates Batik Air and Wings Air, has a dubious safety record, though, and has had more accidents than other airlines in the country. The confusing series of alerts. Due to their size and position, the engines on the Max create lift when the airplane enters a steep climb (or, in aviation parlance, at high angles of attack).

He adjusted the throttle, set the aircraft on its optimal climb slope, and retracted the flaps.Except the airplane didn’t climb. On 13 April 2013, the Boeing 737-800 operating the flight crashed into water short of runway while on final approach to land. "In our opinion, the plane was no longer airworthy and it should not have continued," he said. An hour later, Lion Air flight 043 landed in Jakarta, Indonesia, only a few minutes delayed. It will be key, she says, to understanding what went wrong. In order for different airplane models to share a type certificate, the FAA requires that they all handle the same way. The Maneuvering Characteristics Augmentation System is designed to ensure the wings don’t lose lift, which is known as an aerodynamic stall. They want the airline to fund a search to find the remaining passengers as well as the cockpit voice recorder that hasn't been retrieved. "Sad, grieving, mourning, angry and disappointed - these are all the words that describe how I am feeling. But sometimes it’s not, and you’re showing up at night or in bad weather into an airplane that has all these changes.”There was something else Boeing hadn’t mentioned about the 737 Max.
