Report Defends 'Thorough Work' In Certifying Boeing 737 Max — But Suggests Changes


Amid difficult questions about the steps taken by Boeing and regulators, the review commissioned by the Department of Transportation largely validated the process that put the jetliner in the air.

A pair of Boeing 737 Max 8 jetliners plummeted from the sky in 2018 and 2019, killing hundreds of passengers and eventually prompting officials to ground the aircraft model worldwide — but the process that allowed the craft in the air in the first place is generally sound, according to a review commissioned by U.S. regulators.
An independent committee established by the Department of Transportation published its findings in a 68-page report Thursday. (Skip down to read the whole report.) And broadly, the group found the certification process laid out by the Federal Aviation Administration to be effective, with some changes needed for improvement.
"What we saw was a thorough work by aviation professionals," one of the two co-chairs, former Air Line Pilots Association President Lee Moak, told journalists on a conference call explaining the findings. Together with retired Air Force Gen. Darren McDew, Moak oversaw a five-member panel with a mix of transportation industry executives and former regulators.
"However," Moak added, "we saw where you could improve the system."
Among their recommendations for the FAA:
  • Extend the requirement for Safety Management Systems, or formal, structured programs for risk management. The FAA already requires them for airlines and airports, but the committee recommended applying the mandate to "design and manufacturing organizations," too.
  • Do a better job gathering, analyzing and easing access to aviation data.
  • Improve collaboration with the FAA's counterparts in other countries.
  • Reevaluate and bolster the workforce, including "an aggressive recruitment campaign to encourage students to pursue careers at the FAA."

What was not among its recommendations was any significant adjustment to the FAA's Organization Designation Authorization, a program by which the agency can delegate elements of its certification process to certain approved private individuals or companies. The program drew controversy last year when lawmakers questioned how Boeing ended up being responsible for reviewing changes to its own design on the 737 Max.
"Safety experts have long raised concerns that the [ODA] program leaves the fox in charge of the henhouse," Sen. Richard Blumenthal, D-Conn., wrote in a letter to the Department of Transportation last March, just days after the FAA grounded the Max.
"In short," he added, "the staff responsible for regulating aircraft safety are answerable to the manufacturers who profit from cutting corners, not the American people who may be put at risk."
Further concern surfaced last week with the revelation that Boeing employees had mocked the FAA in internal messages and gloated about the ease with which the plane was approved. "This airplane," read one note about the craft, which would later be involved in the deaths of 346 people, "is designed by clowns who in turn are supervised by monkeys."

But in its review, the panel found no evidence that the outcome of the certification process would have been different if the FAA had not delegated some of the steps.
"The FAA's delegation system is an appropriate and effective tool for conducting aircraft certification," the committee concluded in the executive summary of its report. "It relies on effective standards, oversight and communication between stakeholders."
The review isn't the first to be compiled since the aircraft was grounded. Last October, an FAA-commissioned panel known as the Joint Authorities Technical Review lambasted both the agency and Boeing for failing to properly evaluate the new automated flight control system that directly caused the crashes.
The Justice Department and Transportation Department's Office of Inspector General also are investigating the Boeing plane's certification.
The airline manufacturing giant — now helmed by CEO David Calhoun after Dennis Muilenburg stepped down from the post last month — responded to Thursday's report with gratitude and a commitment to take its findings seriously.
"We will study these recommendations closely," a company spokesperson said in a brief statement, "as we continue to work with government and industry stakeholders to enhance the certification process."
The FAA also welcomed the report's findings.
"I was pleased to see that the committee recommended we advance the use of Safety Management Systems throughout all sectors of the aviation industry," Administrator Steve Dickson said in a statement released by the FAA.
"The agency will carefully consider the committee's work, along with the recommendations identified in various investigative reports and other analyses, as we take steps to enhance our aircraft certification processes."
