Scathing report: FAA dropped the ball when approving 737 Max

The findings also said Boeing exerted “undue pressures” on employees who approved design changes.

U.S. aviation regulators assessing Boeing’s 737 Max sometimes didn’t follow their own rules, used out-of-date procedures and lacked the resources and expertise to fully vet the design changes implicated in two fatal crashes, a review panel comprised of global aviation experts has concluded.

The Federal Aviation Administration, which approved the design of the jet in 2017, dropped the ball on many fronts, the Joint Authorities Technical Review found. A 69-page summary of the findings also said the panel found evidence that Boeing exerted “undue pressures” on some of its own employees who had FAA authority to approve design changes.

The JATR conclusions released Friday are the most sweeping to date to examine how the best-selling Boeing jet, which has been grounded for almost seven months, received approval for what is now seen as a flawed design. The National Transportation Safety Board last month issued recommendations calling for better flight testing for such systems.

There were “an inadequate number of FAA specialists” assigned to the 737 Max’s new design and they “had inadequate awareness” of the system implicated in the two crashes, the report said. Some regulations and policies “were not applied” by the agency as it oversaw design changes on the plane “in a way that failed to achieve the full safety benefit,” it said.

The Joint Authorities Technical Review was established within weeks of the March 10 crash of an Ethiopian Airlines 737 Max near Addis Ababa that killed all 157 aboard and prompted the worldwide grounding of the jet days later. A Lion Air 737 Max went down off the coast of Indonesia on Oct. 29 under similar circumstances, killing all 189 aboard.

The feature known as the Maneuvering Characteristics Augmentation System (MCAS) on the plane was given more authority during the design of the plane, and “the design assumptions were not adequately reviewed, updated, or validated; possible flight deck effects were not evaluated” and safety assessments didn’t keep pace, the JATR said.

Within hours after the release of the report, Boeing announced that CEO Dennis Muilenburg would lose his title as chairman of the aircraft maker. The move will allow Muilenburg to better focus on running the company, according to Boeing’s board of directors, which named one their own, David L. Calhoun, to serve as non-executive chairman.

FAA Administrator Steven Dickson said in a statement he will review the recommendations and “take appropriate action.”

“Today’s unprecedented U.S. safety record was built on the willingness of aviation professionals to embrace hard lessons and to seek continuous improvement,” Dickson said in the statement. “We welcome this scrutiny and are confident that our openness to these efforts will further bolster aviation safety worldwide. The accidents in Indonesia and Ethiopia are a somber reminder that the FAA and our international regulatory partners must strive to constantly strengthen aviation safety.”

In a prepared statement, Boeing said it “is committed to working with the FAA in reviewing the recommendations and helping to continuously improve the process and approach used to validate and certify airplanes going forward.”

Before the report’s release, both the FAA and Boeing had begun taking steps that were similar to its recommendations. For example, the FAA has insisted that the plane be tested by panels of airline pilots instead of relying only on test pilots.

The JATR’s findings paint a picture of an agency that was overwhelmed by the complexity of the new jet’s design, lacking in resources and unaware of the broader safety implications of changes.

However, the panel’s findings were limited to observations and recommendations and didn’t detail the decision making to approve the plane. Because it did not require consensus of all its members, it’s impossible to know if some of the conclusions were by a minority of participants.

The JATR panel was made up of experts from FAA, NASA and nine other regulatory agencies around the world. Participants included the European Aviation Safety Agency as well as representatives from Australia, Brazil, Canada, China, Japan, Indonesia, Singapore and the United Arab Emirates. Its chairman was Christopher Hart, the former chairman of the NTSB.

It was chartered to review how MCAS, the flight-control feature on the 737 Max linked to the two fatal crashes, was approved. It didn’t examine Boeing’s ongoing work with the FAA to redesign the grounded plane and return it to service.

MCAS was added to the Max family of planes to ensure that they met FAA rules for safe handling as the aircraft approached aerodynamic stalls. If the plane was pointed too high, it was programmed to automatically lower the nose. In the crashes, malfunctions caused it to activate and repeatedly try to dive. The failure also led to chaotic cockpit alarms, and both sets of pilots failed to follow Boeing’s procedure to recover and eventually lost control.

In a series of recommendations, the JATR urged the FAA to update its regulations, enhance its engineering expertise and conduct more sweeping safety assessments that examine unintended consequences of high-technology designs.

Like the NTSB’s recommendations last month, it focused on how designs affect humans — in this case, pilots. The complex emergencies in the two accidents and the high pilot work loads “may not have been anticipated in the certification process,” it said. It called on the FAA to better integrate how the agency’s test pilots assess new designs.

It also addressed a concern several pilots unions have raised since the crashes: the lack of reference to MCAS in 737 flight manuals.

Boeing’s Aircraft Flight Manual didn’t include some so-called “non-normal” and emergency procedures “as required by regulations,” the JATR said.

Also, the way in which Boeing withheld information from some manuals meant an FAA panel of pilot experts “was not fully aware of the MCAS function and was not in a position to adequately assess training needs,” it said.

Much of the Max’s design was approved by Boeing engineers who were effectively deputized to act in behalf of the FAA. Congress has ordered the agency to expand such programs in recent years and other regulators around the world use similar processes, in part because aircraft manufacturers have broader expertise.

The JATR recommended that FAA review staffing levels to ensure it can adequately oversee the so-called designees. The Boeing organization that conducts such work has about 1,500 people, while the FAA team overseeing their work has 45. Of that FAA group, only 24 are engineers.

“There are signs of undue pressure” on Boeing employees doing this work, the JATR said, “which may be attributed to conflicting priorities and an environment that does not support FAA requirements.”

The JATR report didn’t provide details on what those pressures were or whether they specifically had an impact on the MCAS design.
