U.S. regulators are revising requirements for how airlines must operate the plane if equipment breaks down after a series of crashes in which 346 people died in Ethiopia and Indonesia in two separate Boeing 737 Max crashes.
Boeing has in the past lost a series of suits filed by Ribbeck Law- a renowned international lawfirm- based on negligence and the un-reliability of its in-flight systems.
In July this year, FAA imposed a $3.9 million penalty on Boeing for using defective plane parts in the wings of some of its models.
FAA argued that the manufacturer had knowingly used the defective parts which a Boeing sub-contractor had certified as substandard in 2018 according to a report by Blomberg.
The penalty does not affect any of the contentious 737 max models which have been grounded following concerns on the safety of their in-flight systems although the model also features the contentious parts.
The U.S. Federal Aviation Administration last week issued proposed new rules for airline operations on the Max that adapt to the fixes being finalized for the grounded jetliner.
The public has 30 days to comment on the document, which was posted on the FAA’s website.
Boeing is also altering the plane’s flight-control computers after tests showed they were vulnerable to failure.
The company must complete an audit of the software changes and test the revised system in flight simulators with a variety of pilots.
In addition to signing off on the redesign, the FAA is devising new pilot training.
