Boeing 737 MAX 8
The Boeing 737 MAX is a series of narrow-body aircraft developed by Boeing Commercial Airplanes as the fourth generation of the Boeing 737. It succeeds the Boeing 737 Next Generation and incorporates more efficient CFM International LEAP engines, aerodynamic improvements such as split-tip winglets, and structural modifications. The program was announced in August 2011, the first flight took place in January 2016, and the aircraft was certified by the U.S. Federal Aviation Administration (FAA) in March 2017. The first delivery, a MAX 8, was made to Malindo Air in May 2017. The 737 MAX series includes four main variants—the MAX 7, MAX 8, MAX 9, and MAX 10—with increasing fuselage length and seating capacity. Boeing also developed a high-density version, the MAX 8-200, launched by Ryanair. The aircraft typically seats 138 to 204 passengers in a two-class configuration and has a range of . , Boeing had delivered 1,844 aircraft and held orders fo ...

Ethiopian Airlines Flight 302
Ethiopian Airlines Flight 302 was a scheduled international passenger flight from Bole International Airport in Addis Ababa, Ethiopia, to Jomo Kenyatta International Airport in Nairobi, Kenya. On 10 March 2019, the Boeing 737 MAX 8 aircraft which operated the flight crashed near the town of Bishoftu six minutes after takeoff. All 149 passengers and 8 crew members on board died. ET 302 is Ethiopian Airlines' deadliest accident to date, surpassing the fatal hijacking of Flight 961 resulting in a crash near the Comoros in 1996. It is also the deadliest aircraft accident to occur in Ethiopia, surpassing the crash of an Ethiopian Air Force Antonov An-26 in 1982, which killed 73 people on board. The accident was the second involving a MAX 8 in less than five months after the crash of Lion Air Flight 610 in the Java Sea. The crashes prompted a two-year worldwide long term grounding of the jet and an investigation into how the aircraft was approved for passenger servic ...

Fuel Economy In Aircraft
The fuel economy in aircraft is the measure of the energy efficiency in transport, transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. Endurance (aeronautics), Endurance and Range (aeronautics), range can be maximized with the optimum airspeed, and economy is better at optimum altitudes, usually higher. An airline efficiency depends on its fleet fuel burn, airline seating, seating density, air cargo and passenger load factor, while operational procedures like aircraft maintenance, maintenance and Airway (aviation), routing can save fuel. Average fuel burn of new aircraft fell 45% from 1968 to 2014, a compounded annual reduction 1.3% with a variable reduction rate. In 2018, CO₂ emissions totalled 747 million tonnes for passenger transport, for 8.5 trillion revenue passenger kilometres (RPK), ...

Boeing 787 Dreamliner
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 without major operating systems was rolled out; subsequently the aircraft experienced multiple delays, until its maiden flight on December 15, 2009.

Rapid Decompression
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all. Such decompression may be classed as ''explosive, rapid'', or ''slow'': * Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma. * Rapid decompression may be slow enough to allow cavities to vent but may still cause serious barotrauma or discomfort. * Slow or gradual decompression occurs so slowly that it may not be sensed before hypoxia sets in. Description The term ''uncontrolled decompression'' here refers to the unplanned depressurisation of vessels that are occupied by people; for example, a pressu ...

Alaska Airlines Flight 1282
Alaska Airlines Flight 1282 was a scheduled domestic passenger flight operated by Alaska Airlines from Portland International Airport in Portland, Oregon, to Ontario International Airport in Ontario, California. Shortly after takeoff on January5, 2024, a door plug on the Boeing 737 MAX 9 aircraft blew out, causing an uncontrolled decompression of the aircraft. The aircraft returned to Portland for an emergency landing. All 171 passengers and 6 crew members survived the accident, with three receiving minor injuries. An investigation of the accident by the National Transportation Safety Board (NTSB) is ongoing. A preliminary report published on February6 said that four bolts, intended to secure the door plug, had been missing when the accident occurred and that Boeing records showed evidence that the plug had been reinstalled with no bolts prior to the initial delivery of the aircraft.

Financial Impact Of The Boeing 737 MAX Groundings
The had a deep financial effect on the aviation industry and a significant effect on the national economy of the United States. No airline took delivery of the MAX during the groundings. A grounding of the 737 MAX 8 lasted between 13 March 2019 and 18 November 2020 and a shorter grounding for the 737 MAX 9 between 6 January 2024 and 25 January 2024. Boeing slowed MAX production to 42 aircraft per month until January 2020, when they halted until the aircraft was reapproved by regulators. Boeing has suffered directly through increased costs, loss of sales and revenue, loss of reputation, victims litigation, client compensation, decreased credit rating and lowered stock value. In January 2020, the company estimated a loss of $18.4 billion for 2019, and it reported 183 canceled MAX orders for the year. In February 2020, the global COVID-19 pandemic and the resulting travel bans created further uncertainty for Boeing. In March 2020, news that Boeing was seeking a $60 billion ba ...

Boeing 737 MAX Certification
The Boeing 737 MAX was initially certified in 2017 by the U.S. Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA). Global regulators Boeing 737 MAX groundings, grounded the plane in 2019 following fatal crashes of Lion Air Flight 610 and Ethiopian Airlines Flight 302. Both crashes were linked to the Maneuvering Characteristics Augmentation System (MCAS), a new automatic flight control feature. Investigations into both crashes determined that Boeing and the FAA favored cost-saving solutions, which ultimately produced a flawed design of the MCAS instead. The FAA's Organization Designation Authorization program, allowing manufacturers to act on its behalf, was also questioned for weakening its oversight of Boeing. Boeing wanted the FAA to type certificate, certify the airplane as another version of the long-established 737; this would limit the need for additional training of pilots, a major cost saving for airline customers.
