U.S. aviation regulators signaled their confidence in the safety of Boeing Co.’s embattled 737 Max jetliner, issuing a global notice of “continued airworthiness” a day after the model’s second deadly crash in less than five months.
There isn’t conclusive evidence so far to link the loss of an Ethiopian Airlines 737 Max 8 on Sunday and a fatal Lion Air disaster involving the same jet model in October, the Federal Aviation Administration said Monday. Boeing is working on improvements to the plane’s flight-control system and the FAA plans to publish a related directive to operators no later than April.
“External reports are drawing similarities between this accident and the Lion Air Flight 610 accident on October 29, 2018,” the FAA said. “However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions.”
The statement signals that U.S. regulators have no immediate intention of grounding the 737 Max 8, breaking with a decision by China and Indonesia to tell its airlines to suspend use of the plane after this weekend’s crash that killed 157 people near Addis Ababa, Ethiopia. Even after the FAA’s announcement, Brazilian airline Gol Linhas Aereas Inteligentes SA said it will also suspend its 737 Max 8 flights.
Boeing’s flight-control changes would address the plane’s anti-stall software and faulty sensor linked to the earlier crash in the Java Sea off the coast of Indonesia.
Boeing sank 5.3 percent to $400.01 at the close in New York, the biggest decline since Oct. 29, the day of the Lion Air crash.
The planemaker echoed the FAA’s statement, saying it stood by the aircraft, a revamped version of its workhorse single-aisle jet. The 737 family is on pace to generate about $30 billion in annual revenue, and about a third of the company’s operating profit, according to George Ferguson, an analyst with Bloomberg Intelligence.
“We are confident in the safety of the 737 Max and in the work of the men and women who design and build it,” Boeing Chief Executive Officer Dennis Muilenburg said in a message to employees shortly after the FAA released its statement.
The Chicago-based company is devoting more resources to the 737 program, including customer support, Muilenburg said. He also reminded employees that all requests on the topic “must flow through the proper channels” as investigators probe the crash.
“There are still many facts to learn and work to be done,” he said. “Speculating about the cause of the accident or discussing it without all the necessary facts is not appropriate and could compromise the integrity of the investigation.”
The FAA’s “Continued Airworthiness Notification to the International Community” is how the FAA communicates about safety issues with other aviation regulators around the world.
With any accident involving a newly certified aircraft model, investigators and regulators pay special attention in the event that an unknown safety issue emerges. The National Transportation Safety Board, which is the lead U.S. agency under a United Nations treaty, sent a team of four investigators and they were joined by others from Boeing and the FAA.
“We’re obviously very concerned about what’s been happening and we’re monitoring the situation very carefully because safety is our number one priority,” Transportation Secretary Elaine Chao said on a conference call Monday with reporters about the department’s budget request.
‘Afraid to Fly’
U.S. carriers such as Southwest Airlines Co., American Airlines Group Inc. and United Continental Holdings Inc. continue to fly the 737 Max. But some labor unions expressed misgivings.
“We do have a few flight attendants who are indicating they are afraid to fly the 737 Max,” said Lori Bassani, president of the Association of Professional Flight Attendants, which represents employees at American. No attendants have refused to fly on the plane so far.
More than 100 of the Boeing planes have been grounded outside the U.S., about one-third of the global Max fleet. The Chicago-based company is slated to deliver 558 of the Max 8 model over the next 12 months, according to Ron Epstein, an analyst with Bank of America Corp.
The U.S. has only grounded an entire model of aircraft twice in the last 40 years. The most recent time was in January 2013 after two lithium-ion battery fires on Boeing’s 787 Dreamliner model. The agency only acted after the second such incident occurred.
