Now, Boeing has to find out how to fix the rays and how to repair its reputation.
737 The Max Rays are by far the most important product for the company. It has orders for nearly 5,000 of the jets, enough to keep the production lines operating in the coming years. But none of the 371
A search for crash causes
] The reason for the Ethiopian airline crash is still unclear. But it was similar to another fatal accident involving 737 Max at the end of October, when a Lion Air flight from Indonesia crashed and killed everything aboard.
Boeing and the FAA had insisted that with proper training, the pilot could overcome security system problems, and that the aircraft could continue to fly while a software upgrade was completed. The upgrade is expected to be available next month.
But as other aviation authorities around the world grounded the jets from Sunday to Wednesday morning, the FAA and Boeing are pushing to act faster.
How to fix the plane
Most experts believe the program upgrade will stop solving any problems to the satisfaction of different authorities.
"The technology is headache but not insurmountable. Damage to reputation is the biggest challenge for everyone," said Richard Aboulafia, vice president of Analysis at Teal Group.
How long the plan stays on the ground, it is still uncertain, "but we guess is weeks and not months," says Cowen Aerospace Analyst Cai Von Rumohr in a note to investors.
Earlier crises for Boeing
Aboulafia said that Boeing has confused inferior crises earlier.
The halt in air travel that rocked the airline industry after the September 11, 2001 attack was a major threat because it was not. It is not clear whether or when the demand for air travel would return. American airlines all needed bailouts to survive that downturn.
A lithium battery problem that led to the founding of 787 Dreamliner for three months 2013 was also a bigger problem.
"Here's the headline tragedy, the horror of 300 deaths," Aboulafia said. "But for Boeing, Dreamliner seemed scary because we didn't know how to fix it, and the consequences of not being able to fix it would have been devastating."
Von Rumohr said another Boeing plan, 727, had four deadly crashes in seven months between 1965 and 1966, shortly after its introduction.
The problem was a training issue, and not mechanical. Pilots were unfamiliar with the three-engine configuration.
"It seemed it would never regain it. The travel agents told customers to fly anything but a 727. It came back from it to be one of the most successful aircrafts" Von Rumohr told CNN Business.
Boeing's economic health
The company had record revenues of $ 101 billion last year, and $ 10.6 billion in profits.
The best news for Boeing when it tries to recover is its strong position in a strong market.
Airlines with 737 Max orders have little opportunity to cancel and replace it with an Airbus plan. Airbus has a substantial backlog, and the airline would also face costs for spare parts and training pilots on a new aircraft type in its fleet.
"Even if you are checked on Boeing, you have to get over it, because you have to do business with them," says airline consultant Mike Boyd.
