Boeing 737 900 Interior Pictures Update Operating Manuals
As part of their decisions, aviation safety agencies in the US, Brazil, Canada, Australia, the UK, the European Union and elsewhere have ordered Boeing and airlines to make repairs to a flight control system blamed for the two crashes that led to the ban update operating manuals and increase pilot training. Two years after it was banned from flying passengers, the Boeing 737 Max has been cleared to return to the skies in much of the world. Front view of a business jet on the runway - boeing 737.

Oliver J Semple Boeing 737-990Februby AirlinesFleet.com. In addition to the flight control system at the center of both investigations, other reports identified concerns with the airliner's flight control computer, wiring and engines.Note: Alaska Airlines Boeing 737-990 N303AS on final Approach into San Francisco International Airport operating Flight AS1252 from Seattle (SEA). Apart from the human tragedy, it was a huge blow to Boeing's business, since the company has thousands of 737 Max orders on its books. The 900 is supposed to be a stretched 737 with revamped lighting and a better cabin, but I had better times in southwest's 737 Posted at 1 day agoThe beleaguered aircraft was grounded worldwide on March 13, 2019, after two crashes, one in Indonesia in 2018 and the other in Ethiopia in 2019, that killed a combined total of 346 people.
Consequently passenger capacity and airplane weight are increased.Airlines are now slowly adding the 737 Max back into their schedules. In general terms this airplane is exact copy of Boeing 737-800 except the length of the airplane that is 3 meters longer. KLM operated 5 narrow-body aircraft Boeing 737-900.
What happened in the two crashes?Korean Airs 737-900ER Lands at Farnborough to Showcase New Boeing Sky Interior. Here's everything else we know about what's happened with the airliner. The plane is now back in service with all US carriers, but Boeing will have to work vigorously to retain the trust of airlines and the flying public in regard to the Max family.
But before the crew could make it back, the aircraft crashed 40 miles from the airport, six minutes after it left the runway. Just after takeoff, the pilot radioed a distress call and was given immediate clearance to return and land. That aircraft was almost brand-new, having arrived at Lion Air three months earlier.The second crash occurred on Mawhen Ethiopian Airlines flight 302 departed Addis Ababa Bole International Airport bound for Nairobi, Kenya. The flight crew made a distress call shortly before losing control. 29, 2018, Lion Air flight 610 dove into the Java Sea 13 minutes after takeoff from Jakarta, Indonesia, killing 189 people.
Like the Indonesian findings, it cites design flaws with MCAS such its reliance on a single angle-of-attack sensor. Report on 737 Max 8 crash blames Boeing design, Lion Air staffOn March 9, 2020, almost one year to the day since the crash in Addis Ababa, Ethiopia's Aircraft Accident Investigation Bureau published an interim analysis. Improper maintenance procedures, confusion in the cockpit and the lack of a cockpit warning light (see next question) contributed to the crash, as well. Investigators also found that MCAS relied on only one sensor, which had a fault, and flight crews hadn't been adequately trained to use the system. Each time they pulled up from a dive, MCAS pushed the nose down again."The MCAS function was not a fail-safe design and did not include redundancy," the report said.
What is the Boeing 737 Max?Built to compete with the Airbus A320neo, the 737 Max is a family of commercial aircraft that consists of four models. They also involve multiple parties including the airline, the airplane and engine manufacturers, and aviation regulatory agencies. Investigators must examine the debris, study the flight recorders and, if possible, check the victims' bodies to determine the cause of death. "There were no known technical problems before departure."Remember that crash investigations are tremendously complex - it takes months to evaluate the evidence and determine a probable cause. "The aircraft has a valid certificate of airworthiness and maintained in accordance with applicable regulations and procedures," the report said. (The Seattle Times has a great deep dive on the report.)Unlike their Indonesian counterparts, the Ethiopian investigators do not mention maintenance problems with the plane nor does it blame the flight crew.
As a whole, the 737 family is the best-selling airliner in history. The Max 9 first flew in 2017, the Max 7 in March, 2018 and the Max 10 on June 18, 2021.The design of the 737 Max series is based on the Boeing 737, an aircraft series that has been in service since 1968. (Malindo no longer flew the plane by the time of the first crash.) Seating between 162 and 210 passengers, depending on the configuration, it's designed for short- and medium-haul routes, but also has the range (3,550 nautical miles, or about 4,085 miles) to fly transatlantic and between the mainland US and Hawaii. 29, 2016, and entered passenger service with Malaysia's Malindo Air on May 22, 2017.
Because they're bigger, and because the 737 sits so low to the ground (a deliberate design choice to let it serve small airports with limited ground equipment), Boeing moved the engines slightly forward and raised them higher under the wing. Boeing 737: Much more than just the MaxThose engines, though, required Boeing to make critical design changes. The 737 Max family compared If you've flown even occasionally, you've most likely flown on a 737.
Most of them quickly grounded their planes a few days later. (For background on MCAS, read these excellent in-depth stories from The Air Current and The Seattle Times.)Compared with previous versions of the 737, the Max's engines sit farther forward and higher up on the underwing pylons.About 30 airlines operated the Max by the time of the second crash (the three largest customers being Southwest Airlines, American Airlines and Air Canada). When a sensor on the fuselage detects that the nose is too high, MCAS automatically pushes the nose down. To keep the nose in trim, Boeing designed software called the Maneuvering Characteristics Augmentation System, or MCAS. A pitched nose is a problem in flight - raise it too high and an aircraft can stall.
Customers may choose additional options, such as alerts and indications, to customize their airplanes to support their individual operations or requirements."But on April 29, 2019, The Wall Street Journal said that even for airlines that had ordered it, the warning light wasn't operating on some Max planes that had been delivered (a fact the Indonesian accident report confirmed). Airplanes are delivered with a baseline configuration, which includes a standard set of flight deck displays and alerts, crew procedures and training materials that meet industry safety norms and most customer requirements. When asked about the warning light, a Boeing spokesman gave CNET the following statement:"All Boeing airplanes are certified and delivered to the highest levels of safety consistent with industry standards. But following President Trump's decision to ground the Max that day, the agency cited new evidence it had collected and analyzed.Older 737 models, like the 737-700, 737-800 and 737-900, don't use MCAS and weren't affected.Of the four 737 Max versions, only the Max 10 has yet to fly.What was the problem with the warning light?The Air Current reported Mathat the Lion Air plane lacked a warning light designed to alert pilots to the faulty sensor and that Boeing sold the light as part of an optional package of equipment. Canada initially hesitated, but soon reversed course.Up until March 13, 2019, the FAA also declined to issue a grounding order, saying in a statement tweeted the previous day that there was "no basis to order grounding the aircraft." That was despite a public outcry from a group of senators and two flight attendant unions. China (a huge Boeing customer and a fast-growing commercial aviation market) led the way and was joined by Indonesia, Thailand, Malaysia, Australia, India, Oman, the European Union and Singapore.
