Joint intentional aviation regulators criticized Boeing and the US Federal Aviation Administration (FAA) for the failure of 737 MAX aircraft.
Joint Authorities Technical Review (JATR), consisting of technical representatives from the FAA, National Aeronautics and Space Administration (NASA), and civil aviation authorities from Australia, Brazil, Canada, China, Europe, Indonesia, Japan, Singapore, and the United Arab Emirates released a report on Friday after reviewing update fix of MCAS software on 737MAX.
A report issued Friday by the Joint Authorities Technical Review (JATR) said it determined the FAA had followed outdated procedures used to certify five decades old 737 to certify 737MAX., and failed to apply its own rules while lacking the manpower and expertise to effectively oversee how the MCAS changed the handling of the 737 MAX compared with older 737 designs.
“Although existing standards have served the industry well for decades, the JATR members recommend an examination of whether those standards are as appropriate for the complex integrated systems in today’s airplanes. For example, when the failure or inappropriate operation of a system results in cascading failures and multiple alarms, query how adequately the certification process considers the impact of multiple alarms, along with possible startle effect, on the ability of pilots to respond appropriately. Inherent in this issue is the adequacy of training to help pilots be able to respond effectively to failures that they may never have encountered before, not even in training.” reads JATR report
Report also said, Boeing altered the design of the MCAS during the certification to make it more powerful, but neglected to inform the FAA of changes.
The JATR committee concluded that Boeing influenced FAA in certification process, and “hope they(FAA) will help improve the certification process in ways that will continue to improve safety.”
