Até onde sei eles estão em CNF.

PR-XMA ao PR-XMG estão no Brasil. Os demais já produzidos, ainda não foram oficialmente entregues e estão nos EUA (uns em Victorville, alguns na própria Boeing).

Southwest pilots seek changes to 737 MAX runaway stabilizer procedure

By David Shepardson

NOVEMBER 2, 2020

The union representing pilots at Southwest Airlines on Monday urged U.S. regulators to simplify the procedure recommended to address an emergency that can force down the nose down of the Boeing 737 MAX, an issue in both of two fatal crashes and the plane’s grounding.

Monday was the deadline for submitting public comments to the U.S. Federal Aviation Administration (FAA), which on Oct. 6 released a draft report on revised training procedures for the MAX that has been grounded since March 2019 after two fatal crashes killed 346 people.

The FAA proposal adds new training requirements to deal with a safety system called MCAS tied to both fatal crashes.

Separately, the families of many victims of the March 2019 Ethiopian Airlines Flight 302 737 MAX crash opposed the training changes as “inadequate.”

The families called the changes “insufficient to ensure that 737 MAX pilots are properly equipped to handle all MCAS-related emergencies and prepared to serve as the last line of defense against another tragedy.”

The FAA is requiring new safeguards to MCAS, including requiring it receive data from two sensors, before it allows the 737 MAX to return to service.

Pilots will undergo new simulator training before they can resume flights, including training on multiple flight deck alerts during unusual conditions along with how to respond to a runaway stabilizer with timely pilot actions required.

In both crashes, pilots grappled with Boeing’s flawed MCAS flight control system, which repeatedly forced down the jet’s nose, and multiple audio and visual warnings.

The Southwest pilots union said the revisions to the runaway stabilizer procedure should be simplified.

The union added “error rates increase exponentially with a

checklist containing eight memory steps including three conditional steps.” After testing the checklist in a MAX “simulator” the union “found it difficult to recall the steps in order, and furthermore find this checklist is ‘clunky at best.’”

The union recommends redesigning the procedure.

The British Airline Pilots Association proposed changes including requiring all five MAX special flight training elements be conducted in a MAX full-flight simulator, instead of allowing some in a 737-NG simulator.

The Allied Pilots Association recommend reducing intervals for recurrent training on runaway stabilizer from 36 months to 24 months.

Boeing declined to comment. An FAA spokesman said the agency “will evaluate all the comments we receive.”

Reuters reported earlier the FAA could unground the MAX as early as mid-November.

É um importante feedback.

Não adianta ter memory items complexos, que não serão lembrados.

Apesar de eventuais simplificações com o passar dos anos, os aviões da Boeing ainda apresentam uma série de procedimentos baseados em ações que não dão margem para consultar o manual antes de manter a aeronave sob controle. É agir e prosseguir na leitura de um cheque quando der. 

Ok, a grande maioria dos itens de memória é intuitiva e segue uma lógica natural, mas jamais será surpreendente observar se um piloto alterar a sequência ou esquecer-se de cumprir todos os itens ou realiza-los erroneamente. Sob pressão, até o básico pode ser complicado. 

Claro que o enfoque agora é encontrar uma solução para esse enorme problema associado com o MCAS, mas certamente não será a única situação, memorizada ou não, que pode comprometer consideravelmente a segurança na condução das operações se não for corretamente executada.

EXCLUSIVE-FAA in final stages of Boeing 737 MAX review; could approve as early as Nov. 18

The U.S. Federal Aviation Administration is in the final stages of reviewing proposed changes to Boeing Co’s 737 MAX and expects to complete the process in the “coming days,” the agency’s chief told Reuters on Monday.

Three sources briefed on the matter told Reuters the FAA is set to approve the plane’s ungrounding as early as Nov 18. FAA Administrator Steve Dickson told Reuters in a statement that he expects “this process will be finished in the coming days, once the agency is satisfied that Boeing has addressed” safety issues involved in two fatal crashes that killed 346 people. Boeing declined to comment.

The strapped planemaker has also approached United Airlines Holdings Inc., Alaska Air Group Inc. and Delta Air Lines Inc. about taking some of the planes that lack buyers, the people said. Of the 450 or so Max built during the flying ban, nearly a quarter are white tails, one of the people said.

Boeing loses more 737 MAX orders, eyes jet's U.S. return but Europe tariffs loom

By Eric M. Johnson

NOVEMBER 10, 2020

Boeing Co lost another 12 orders for its grounded 737 MAX jetliner in October, and delivered 13 aircraft to customers, down from the 20 jets delivered in the same month a year ago, company data showed on Tuesday.

For the second straight month, the closely watched monthly snapshot revealed 787 Dreamliner quality flaws and the coronavirus pandemic kept hampering Boeing’s efforts to develop an alternative cash cow to the 737 MAX.

The U.S. Federal Aviation Administration (FAA) appeared about a week away from lifting a March 2019 safety ban, although the pandemic kept hammering demand for jets from Boeing and European rival Airbus.

Airbus sold 11 jets last month and booked 72 jet deliveries, easing concerns over a cash-depleting overhang of unwanted jets.

The European Union’s decision to impose tariffs of 15% on Boeing planes this week could hobble its jet deliveries in Europe.

Boeing said it lost orders for four 737 MAX jets from China Development Bank Financial Leasing Co, one from Czech Airlines owner Smartwings, three from Oman Air, and four from an undisclosed buyer or buyers.

Canceled MAX orders, including those where buyers converted to a different model, was 448 jets - and 460 for all jets across Boeing’s portfolio, Boeing said.

For 2020 through October, the number of MAX orders canceled, or removed from Boeing’s official backlog when it applies stricter accounting standards, stood at 1,043 aircraft.

For deliveries - a key metric since customers hand over most of the money at the time they pick up new aircraft - Boeing handed over 13 twin-aisle jets in October, compared to 20 a year earlier and 10 in September.

That brings total deliveries to 111 aircraft in the 10 months through October 2020, down from 321 for the same period a year ago.

The October delivery tally included one P-8 maritime patrol aircraft, one 747 and three 767 freighters to United Parcel Service, two 777 freighters to China Cargo Airlines, one 777 to German logistics company DHL, and one 777-300ER to Dubai-headquartered Novus Aviation Capital, Boeing said.

Boeing also delivered four 787s in October: one 787-8 to American Airlines, one 787-9 to Leasing giant AerCap, one 787-10 to Abu Dhabi’s Etihad Airways, and one 787-10 Saudi Arabian Airlines.

Boeing perde mais pedidos de 737 MAX, vislumbra o retorno do jato aos Estados Unidos, mas tarifas europeias se aproximam

Por Eric M. Johnson

10 DE NOVEMBRO DE 2020

A Boeing Co perdeu outros 12 pedidos de seu jato 737 MAX aterrado em outubro e entregou 13 aeronaves a clientes, abaixo dos 20 jatos entregues no mesmo mês um ano atrás, mostraram dados da empresa na terça-feira.

Pelo segundo mês consecutivo, o instantâneo mensal observado de perto revelou falhas de qualidade no 787 Dreamliner e a pandemia de coronavírus manteve os esforços da Boeing para desenvolver uma vaca leiteira alternativa ao 737 MAX.

A Administração Federal de Aviação dos Estados Unidos (FAA) apareceu cerca de uma semana antes de suspender a proibição de segurança em março de 2019, embora a pandemia continuasse martelando a demanda por jatos da Boeing e do rival europeu Airbus.

A Airbus vendeu 11 jatos no mês passado e reservou 72 entregas de jatos, diminuindo as preocupações com a projeção de jatos indesejados que esgotam o caixa.

A decisão da União Europeia de impor tarifas de 15% aos aviões da Boeing nesta semana pode prejudicar as entregas de jatos na Europa.

A Boeing disse que perdeu pedidos de quatro jatos 737 MAX do China Development Bank Financial Leasing Co, um da proprietária da Czech Airlines, Smartwings, três da Oman Air e quatro de um comprador ou compradores não divulgados.

Os pedidos MAX cancelados, incluindo aqueles em que os compradores foram convertidos para um modelo diferente, foram de 448 jatos - e 460 para todos os jatos do portfólio da Boeing, disse a Boeing.

Para 2020 até outubro, o número de pedidos MAX cancelados ou removidos da carteira oficial da Boeing quando ela aplica padrões contábeis mais rígidos foi de 1.043 aeronaves.

Para entregas - uma medida importante, já que os clientes entregam a maior parte do dinheiro no momento em que pegam uma nova aeronave - a Boeing entregou 13 jatos de corredor duplo em outubro, em comparação com 20 um ano antes e 10 em setembro.

Isso traz um total de entregas para 111 aeronaves nos 10 meses até outubro de 2020, ante 321 no mesmo período do ano anterior.

A contagem de entrega de outubro incluiu uma aeronave de patrulha marítima P-8, um 747 e três cargueiros 767 para a United Parcel Service, dois cargueiros 777 para a China Cargo Airlines, um 777 para a empresa de logística alemã DHL e um 777-300ER para Novus sediada em Dubai Capital da aviação, disse a Boeing.

A Boeing também entregou quatro 787s em outubro: um 787-8 para a American Airlines, um 787-9 para a gigante da Leasing AerCap, um 787-10 para a Etihad Airways de Abu Dhabi e um 787-10 Saudi Arabian Airlines.

Mais de um ano com todos os jatos no chão, tremendo prejuizo.

Quase 2 anos... 

Acho que agora o financeiro tem toda a certeza que um avião novo seria bem melhor e que afobado come cru

A partir desta diretriz da FAA, a ANAC procederá com os ajustes finais para conclusão do processo de validação para retorno do modelo Boeing 737- 800 MAX no Brasil. Após o término desse trabalho, o operador brasileiro da aeronave, que atualmente é a GOL Linhas Aéreas, deverá incorporar e demonstrar de forma satisfatória o cumprimento de todas as novas diretrizes, tanto em termos de projeto quanto de treinamento de pilotos.

No início de dezembro a AA iniciará voos não comerciais, até o primeiro voo com pax no dia 29 de dezembro (MIA-LGA). São 2.600 pilotos de B737MAX que necessitarão de treinamento obrigatório do FAA (treinamento baseado em computador, briefings em sala de aula e treinamento dedicado ao serviço em um simulador 737 MAX)

64 mil horas de trabalho da manutenção para manter as aeronaves prontas para o retorno. Creio que na GOL os trabalhos também estejam sendo mantidos para o retorno das aeronaves

“Transport Canada safety experts continue their independent validation process to determine whether to approve the proposed changes to the aircraft. We expect this process to conclude very soon. However, there will be differences between what the FAA has approved today, and what Canada will require for its operators. These differences will include additional procedures on the flight deck and pre-flight, as well as differences in training.

“The commercial flight restrictions for the operation of the Boeing 737 MAX aircraft in Canadian airspace remain in effect and will not be lifted until the department is fully satisfied that all its safety concerns have been addressed, and that enhanced flight crew procedures and training are in place in Canada.”

450 x $40 milhões por avião = $18 bi, será que vai ter financiamento pra isso tudo, ainda mais com as prestações dos leasings em queda?

https://www.iba.aero/insight/depressed-outlook-for-737-max-lease-rates/

 

270k x 12 meses x 12 anos = $38.9 milhões  só vão conseguir recuperar o investimento no 2º leasing.

Q&A: What led to Boeing’s 737 MAX crisis

é bem extensa essa matéria, o que me chamou atenção, isso é verdade?

 

  • Why didn’t Boeing tell pilots about MCAS before the crashes?

The pilots of the Lion Air plane had no awareness of MCAS, as it wasn’t detailed in the flight manual. Boeing first informed pilots around the world of the existence of MCAS almost two weeks after the Lion Air crash.

Boeing says MCAS was supposed to act in the background in rare circumstances. It decided the pilots didn’t need to know about the system and shouldn’t be overloaded with the information. The reasoning was that if MCAS went wrong, there is a standard procedure pilots should know for dealing with uncommanded movement of the horizontal tail: cut electric power to the tail and move it manually.
