The Federal Aviation Administration plans to revamp oversight of airplane development after the two deadly crashes of Boeing's new 737 Max raised questions of whether the FAA has gone too far in letting companies regulate themselves, according to testimony prepared for a Capitol Hill hearing on Wednesday.
For decades, the FAA has delegated some authority for certifying new aircraft to the manufacturers themselves, reducing government costs and, defenders say, speeding the rollout of new models.
But in the wake of the air disasters in Ethiopia and Indonesia over less than five months, that practice has been seized on as evidence of an overly cozy relationship between the FAA and the industry.
The self-certifying practice, called Organization Designation Authorization, was expected to come under scrutiny Wednesday at a Senate subcommittee hearing where the acting FAA administrator, Transportation Department inspector general and chairman of the National Transportation Safety Board were scheduled to appear.
In testimony prepared for the hearing, Inspector General Calvin Scovel III said the FAA plans to significantly revamp its oversight of aircraft development by July. He gave few details but said the changes would include new ways to evaluate training and self-audits by aerospace companies.
Over the years, the inspector general's office has found management weaknesses in the agency's oversight, Scovel said in testimony obtained by The Associated Press.
The Max, featuring bigger, more efficient engines and a new automated anti-stall system that has now come under suspicion in both air disasters, went into service in 2017.
Transportation Secretary Elaine Chao, who oversees the FAA, has asked Scovel to look into the way the agency certified the 737 Max as airworthy.
At the same time, the Justice Department is investigating possible criminal violations involving the airliner's certification.
Acting FAA Administrator Daniel Elwell's prepared testimony also hinted at coming changes at the FAA but gave few details.
"We know that our oversight approach needs to evolve to ensure that the FAA remains the global leader in achieving aviation safety," he said.
Elwell also said Boeing submitted an application on Jan. 21 spelling out changes it planned to make to crucial flight-control software on the 737 Max — the system suspected of playing a role in the Oct. 29 crash of a Lion Air jet in Indonesia and the March 10 plunge of an Ethiopian Airlines Max. In all, 346 people died.
FAA engineers and pilots have tested the software update in a simulator and the plane, according to his prepared remarks. "The FAA's ongoing review of this software installation and training is an agency priority," Elwell said.
An FAA spokesman said Wednesday that the Boeing submission was an "initial application" and that the agency had not yet received Boeing's completed plan for updating the software.
The Transportation Department watchdog has previously raised questions about the FAA's certification of Boeing planes and the seemingly close relationship between some agency managers and Boeing.
Elwell defended collaboration with aircraft makers and airlines, saying that sharing information gives the FAA more knowledge about emerging risks. The process, he said, has "consistently produced safe aircraft designs for decades."
The inspector general also plans to examine the widespread use of automated systems to fly airplanes and look into whether the FAA is making sure airlines are adequately training pilots to handle situations when such features fail.
Multiple investigations into the 737 Max crashes are focusing on the new automated system that can push the plane's nose down to prevent an aerodynamic stall.
Meanwhile, in Seattle, Boeing's vice president of airplane development, Mike Sinnett, briefed reporters on changes that the company is making to the flight-control system and pilot training. He repeated Boeing's confidence in the safety of the Max.
"We are working with customers and regulators around the world to restore faith in our industry and also to reaffirm our commitment to safety and to earning the trust of the flying public," Sinnett said.
Boeing also invited about 200 pilots from several airlines to its Seattle-area facility to explain to them the changes in the Max and "to get their input and to earn their trust," Sinnett said.
