US Department of Transportation Report: “Defects” in Boeing 737 MAX Certification Process


p > The Office of the Inspector General of the U.S. Department of Transportation stated in a 60-page report that “defects” in the 737 MAX certification process affected the testing of the aircraft, and this aircraft was allowed to fly in 2017.

The report said: “We have found limitations in the guidance and procedures of the Federal Aviation Administration (FAA), which affected the certification process and led to a serious misunderstanding of the Maneuvering Characteristics Enhancement System (MCAS). The MCAS software is believed to have caused these two accidents.”

The investigation found that the FAA “did not fully understand Boeing’s safety assessment of MCAS until after the first (crash) accident.” The first air crash occurred in October 2018. A Lion Air flight crashed near Indonesia, killing 189 people.

In just 5 months, another Boeing 737 MAX of Ethiopian Airlines crashed, resulting in 157 deaths.

A few days before the publication of this report, an engine failure and fire occurred on a Boeing 777 passenger plane, and debris fell along the way.

In the report, the U.S. Department of Transportation put forward 14 recommendations for FAA to identify potential risks in a timely manner, including calling on the FAA to analyze the “probability of failure”, and “implementing procedures for manufacturers to formally notify FAA certified engineers to system Any changes to the safety assessment, including after the start of the flight test”.

The report includes a statement from the FAA stating that the regulator agrees with the report’s conclusions. The FAA stated that measures have been taken to “ensure a more comprehensive assessment of aircraft design changes.”
