FAA releases preliminary report for the Boeing's updated anti-stall software

Washington - On April 16, the U.S. Federal Aviation Administration cleared its preliminary analysis about the Boeing's long-awaited software update to the anti-stall system of the 737 MAX jets.

According to the Agency, the proposed software and training updates are "operationally suitable."

The draft released by the Flight Standardization Board suggests that flight crews be trained via computer-based systems for the 737 MAX's anti-stall software known as MCAS (Maneuvering Characteristics Augmentation System), which is believed of contributing to two fatal crashes in less than half a year.

Boeing teams carried out 196 hours of flight to test the new anti-stall software of the aircraft. The manufacturer already began to brief the 737 MAX operators about the changes by bringing airline representatives, pilots, and technical personnel into flight simulators.

After the second 737 MAX 8 crash in Ethiopia on March 10, regulators around the world imposed temporary flight ban for the all 737 MAX jets. Upon this development, Boeing had to suspend the deliveries and cut production of the aircraft by 20%.

371 Boeing 737 MAXs have been grounded since mid-March. According to financial analysts, the losses of Boeing exceeded one billion dollars.

Separately, Boeing has received strong criticism from the representative firms of its shareholders. Yesterday, two Institutional Shareholder Services recommended that Boeing should have an independent chairman of the board. This title is currently held by CEO Dennis Muilenburg.

Institutional Shareholder Services believe that Boeing CEO Dennis Muilenburg should no longer play a double role. The ISS also advised that the head of the so-called audit committee at Boeing should be replaced.
