In Summary
  • The FAA was the last global aviation authority to ground the 737 MAX after one of the aircraft crashed in Ethiopia.
  • The JATR was tasked with reviewing the approval procedures for the 737 MAX and make proposals to improve them.
  • There are differences among regulators on the criteria for returning the MAX to service.

New York

A panel of global civil aviation authorities is expected to criticise the US Federal Aviation Administration (FAA's) approval of Boeing's 737 MAX, which has been grounded for six months following two crashes, a source familiar with the matter said Monday.

The panel, known as the Joint Authorities Technical Review (JATR), was set up last April by the FAA amid criticism of the FAA'S close ties to Boeing.

The FAA was the last global aviation authority to ground the 737 MAX after one of the aircraft crashed in Ethiopia in March, leaving 157 dead, a few months after another went down in Indonesia, killing 189.

APPROVAL PROCEDURES

The JATR – which brings together experts from nine international aviation authorities as well as the FAA and NASA – was tasked with reviewing the approval procedures for the 737 MAX and make proposals to improve them.

According to the source, the report, which must be submitted in the coming weeks, is critical of the FAA.

TRANSPARENCY

In particular, it is expected to take aim at the lack of transparency in the way that the FAA permitted Boeing to evaluate systems and software for the MAX, the source said on condition of anonymity.

The panel is expected to conclude that important changes to the design of the MAX were not properly reviewed by the FAA, according to the source.

For example, it was Boeing employees who inspected the MCAS anti-stall system, which has been implicated in the deadly crashes, sources previously told AFP.
