Boeing 737 max 8 crash. The Boeing 737 MAX 8 Crashes: The Case for Pilot Error 2020-02-02

Ethiopian Airlines Boeing 737 MAX crash update

Currently the three largest customers in order are Southwest Airlines, American Airlines and Air Canada. But the new position of the engines changed how the aircraft handled in the air, creating the potential for the nose to pitch up during flight. If you get the desired state by moving a switch or control, then keep it there. Airbus had a one-year jump over Boeing in the development and production of its new plane, the A320neo aircraft. Finally, the pilots committed a cardinal sin of aviating: problem-solving. Misunderstood or, worse, mismanaged, it can result in tragic accidents.

Ethiopian Airlines Boeing 737 MAX crash update

The pilots, once again, committed a cardinal sin of aviating: problem-solving. Ethiopia Airlines, for its part, defended its senior captain, Yared Getachew, stating that he had completed 8,000 hours in the air. Of the four 747 Max versions, only the Max 10 has yet to fly. Instead of correcting the problem, the pilots were making it worse. But some pilots and regulatory officials from other countries, like Canadian Transport Minister Marc Garneau, have disagreed with that decision. The similarities may only be a coincidence.

We believe that the final accident report will or should reflect this finding. Older , like the 737-700, 737-800 and 737-900, don't use the flight control system under investigation and aren't affected. As was noted in the crash report, the airline cut corners wherever it could, including by installing a misaligned sensor onto the Max 8 that crashed. This occurred on climb-out and immediately after the flaps were retracted. Interestingly, the flight data recorder revealed that the stick shaker activated on liftoff, but the captain stated in the report that it came on at 400 feet. Inappropriate transfer of aircraft control during a critical phase of the emergency Fatal Pilot Errors 1.

Pilots for airlines elsewhere in the world train under a different system that requires fewer flight hours than their American counterparts, and Nur had only 200 hours of experience, an unthinkably low total for a first officer on a 737 for a U. Pilot experience and training Some U. Figure 11: Lion Air Flight 610: Examination of the Flight Control Parameters If this solved the problem, then why did the plane crash seven minutes later? The Ethiopian Airlines flight was in the air for six minutes; the Lion Air flight for 12. A malfunction with this system, where it appeared to activate based on faulty readings from a flight sensor, is the suspected cause of both crashes. The Lockheed L-1011, introduced in 1972,. The that was launched by Boeing to counter rival Airbus' best-selling A320. We believe that no experienced or properly trained pilot would have transferred control of the yoke to the non-flying pilot under these critical circumstances.

Boeing 737 MAX 8 plane crashes: What we know about two fatal flights

Years of empirical data obtained through countless takeoffs and landings provide a seasoned pilot with skill that is hard to quantify. If you've flown even occasionally, you've most likely flown on a 737. The overspeed warning is a loud aural tone to alert pilots that the aircraft has exceeded its maximum airspeed and is a non-normal checklist item requiring pilots to reduce power and slow down. Poor maintenance of these sensors led to the system thinking that the plane was travelling sharply upward, the publication reported. Boeing was in a competitive race against its European-based rival Airbus to maintain and strengthen its dominance of the market for short- and mid-range aircraft, particularly in the rapidly expanding Asian market.

We fell short in the implementation of the AoA Disagree alert and are taking steps to address these issues so they do not occur again. Just after takeoff, the pilot radioed a distress call and was given immediate clearance to return and land. It is more fuel-efficient than the 737, and seats more people despite being a similar size. It points to the basic antagonism between the interests of society, including safe, efficient and inexpensive air travel, and the private ownership of basic industries, as well as the division of the world economy among rival nation states. So, why did the Lion Air pilots act differently than U. What about the warning light? The Lion Air crash occurred on October 29th, 2018. More than 40 countries have also banned the 737 Max from flying in their airspace.

Even the slightest hint of possibly existing similarities to the Lion Air accident should have at least forced them to stay quiet if not to be the very first to ban the aircraft , until enough evidence was gathered that indeed pointed in that direction. Boeing promoted its Max 8 version of the 737 to potential airline customers largely on the basis of the claim that it was cheaper to purchase and put into operation because it required virtually no additional training for pilots with previous 737 flight experience. It is not yet known whether it resulted from human error or a technical issue. Wall Street rewarded Boeing with a near-quadrupling of its stock price and record profits. What's different about the 737 Max series compared with earlier 737s? The larger first flew in 2017, and the 737-10 is still in development and has yet to fly.

What happened in the two crashes? It is drilled into U. The captain depended on the first officer to manage the automation and monitor key tasks, making sure that what the captain asked for was done. Boeing The actions of the Ethiopian flight crew are under investigation as well. In fact, it is standard practice for U. The , diving into the certification process and internal affairs at the time.

The previous four The Indonesian preliminary report goes over the maintenance write-ups of the previous four flights of the fatal aircraft. A mistake that Lion Air flight 43 avoided by keeping their airspeeds below 250 knots, which allowed the pilots to better manage the manual trim—because of the significantly lower aerodynamic force on the large horizontal stabilizer. The result was that the plane immediately went from a state of climbing to losing 100-200 feet, which is significant during the initial climb-out phase of flight. The pilots immediately had trouble controlling the pitch of the plane once it was in the air. Websites like and can show the type of plane model for a specific flight.

It said the changes had been in the works since the Lion Air crash in October. What is significant about these dates? The latest crashes, Wright says, are likely to influence the design philosophy about how similar features are introduced to different aircraft. At 380 knots, the aerodynamic forces acting on the tail portion of an aircraft stabilizers and elevators are enormous, especially at lower altitudes where the air is denser—the aircraft was between 9000 feet and 12,000 feet pressure altitude. The airliner around the world, and the Federal Aviation Administration is under scrutiny for its certification process. However, flying skill and proficiency are still crucial even though, in reality, modern aircraft are forgiving and easy to fly, making the skies safer than ever before. This action would be their last in a series of mistakes Once the electric stab trim was back on, they quickly initiated the electric yoke mounted trim to relieve pressure on the back stabilizer— remember, the last position of the stabilizer trim was 2. The developments are a huge blow to Boeing, which has thousands of 737 Max orders on its books.
