After 2 Crashes of New Boeing Jet, Pilot Training Now a Focus

The chief government of Boeing backed down on Wednesday. He referred to as President Trump to suggest that the United States quickly take the corporate’s best-selling jet out of service, following two lethal crashes in lower than 5 months. Hours later, the president introduced that the aircraft had been grounded.

It was a stark reversal for Boeing, an industrial juggernaut that has loved a decade of fast progress and has deep ties in Washington. Just the day earlier than, the chief government, Dennis A. Muilenburg, had urged the president to maintain the aircraft flying, as regulators around the globe banned the jet.

The aircraft, the 737 Max, was deeply rooted within the firm’s psyche, a reflection of its engineering prowess and its enviable security document. But it was additionally born out of necessity as the corporate competed aggressively with its European rival Airbus.

The stakes for Boeing are excessive, with four,600 pending orders that promise to herald lots of of billions of . All that’s in danger as regulators and lawmakers start to analyze what went unsuitable with the doomed Ethiopian Airlines flight and an earlier one on Lion Air. Some carriers are already reconsidering their purchases.

One space of focus is whether or not the coaching procedures on Boeing’s jet, greenlighted by the Federal Aviation Administration, left pilots unprepared to take care of new software program on the aircraft. When the aircraft was launched, Boeing believed that pilots who had flown an earlier mannequin didn’t want further simulator coaching and regulators agreed. The F.A.A. didn’t change these guidelines after the Lion Air crash in October and there aren’t any plans to take action now.

Although the investigations are persevering with, preliminary proof and information counsel potential similarities between the crashes, elevating questions in regards to the new software program on which pilots weren’t educated. Evidence at the Ethiopia crash site suggests there could have been a problem with the software, an automated system designed to help avoid a stall, which has also come up in the Lion Air disaster.

When Airbus announced in 2010 that it would introduce a new fuel-efficient and cost-effective plane, Boeing rushed to get out its own version. The strategy depended heavily on building a plane that worked essentially the same as the previous generation. Regulators agreed that it was a derivative model and that it didn’t require additional simulator training, a significant savings for airlines.

For many new airplane models, pilots train for hours on giant, multimillion-dollar machines, on-the-ground versions of cockpits that mimic the flying experience and teach them new features. But in the case of the Max, many pilots with 737 experience learned about the plane on an iPad.

“We would have liked to have had a simulator” from the start, said Jon Weaks, the president of the Southwest Airlines Pilots Association. “But it wasn’t practical, because it wasn’t built yet.”

As Boeing pushed to get the plane done, flights simulators designed specifically for the Max weren’t ready. Greg Bowen, the training and standards chair at the Southwest pilots association, said that senior leadership at the carrier told him the engineering data necessary to design simulator software was still being finalized right up until the plane was nearly completed.

“They were building the airplane and still designing it,” Mr. Bowen said. “The data to build a simulator didn’t become available until about when the plane was ready to fly.”

When United was set to take delivery of the 737 Max in 2017, a group of pilots put together training materials without ever flying the aircraft or a full simulator. James LaRosa, a 737 captain and union official who helped lead the training group, said he flew to a Boeing training center in Seattle to learn about the new plane on a mock cockpit that didn’t move like typical simulators.

In addition to a two-hour iPad training course from Boeing, he and colleagues used their experience in the cockpit to create a 13-page handbook on the differences between the Max and its predecessor, including changes to displays and the engines. The training materials did not mention the new software that later became a focus of the Lion Air crash investigation.

“When you find out that there are systems on it that are wildly different that affect the performance of the aircraft, having a simulator is part of a safety culture,” said Dennis Tajer, a spokesman for the American Airlines pilot union and a 737 pilot. “It can be the difference between a safe, recoverable flight and one that makes the newspapers.”

Boeing said in a statement that “the 737 Max was certified in accordance with the identical F.A.A. requirements and processes that have governed certification of all previous new airplanes and derivatives.”

“The F.A.A.’s aircraft certification processes are well established and have consistently produced safe aircraft designs,” the regulator said in a statement.

After the Lion Air crash that killed all 189 people aboard, the new software on the plane became an area of focus for investigators and pilots.

The new engines on the planes were bigger, part of Boeing’s competitive push to make it more fuel efficient. To compensate for the different aerodynamics that were the result of the larger engines, Boeing installed a system, known as MCAS, that automatically pushes the plane’s nose down in certain circumstances. A central concern in the Lion Air disaster is that the system may have malfunctioned, based on faulty sensor readings.

After the crash, it was clear that pilots of the 737 Max had not been fully informed about the new software. Shortly after Thanksgiving, pilot unions from Southwest and American met separately with Boeing officials. The unions wanted answers.

“The first thing we talked about was the break of trust,” said Mr. Tajer, the American pilot union spokesman. “We called it disrespectful.”

According to Mr. Tajer, Boeing officials told American’s pilots that they hadn’t mentioned the new software because they didn’t want to “inundate” them with information.

The union told Boeing that it was now demanding simulators for its pilots. “We don’t really care what the F.A.A. requires,” Mr. Tajer said, recalling the meeting.

Pilots at American Airlines, who began asking for simulators for the new model as soon as they started flying the planes, ramped up their requests after the Lion Air crash.

Boeing officials promised American and Southwest pilots a software fix within several weeks, but added that extra training was not necessary. Notifying the pilots of the nature of the software fix and how it would function would be enough.

The airlines agreed. After those meetings, the pilots from both unions said that they were certain that they could keep flying the plane safely, even without simulators. Once they had been told how the new software worked, they believed they had “all the information on the system and the ability to interrupt it if it went afoul,” said Mr. Tajer.

Representative Peter A. DeFazio, Democrat of Oregon and the chairman of the House transportation committee, said he asked F.A.A. officials after the Lion Air crash why more substantial training was not required.

“I said, ‘This is essentially a different airplane, and how is it that it was certified without requiring pilot retraining?’” Mr. DeFazio recalled. He said the F.A.A. defended what had been decided as the work of pilots and others who “came to a consensus decision.”

“Would I go out and fly one today and put my family on it? Yeah, I would. Because I know how to fly it,” said Michael Michaelis, the top safety official at the American Airlines pilots union and a 737 captain. “But I would like to see the fix done and have a full briefing from the manufacturer about what this thing is really going to do and how it’s going to do it.”

And airlines are getting flight simulators, even if they aren’t required by regulators. One flight simulator maker has received 40 orders.

It will be months before pilots in the United States can use them.

Hours after the Ethiopian Airlines crash, Mr. Tajer, the American Airlines union spokesman, spoke with the carrier and asked for an update on the simulator request. The reply: One had been ordered, and pilots would be able to train on it by the end of this year.

United Airlines, the world’s third-largest carrier, was told that it has to wait until 2020 for one. Today, there is only one simulator specifically designed for the Max in the United States.
