Regulators laid out plans on Monday (August 3) that could get the troubled Boeing 737 MAX back in the skies.
The U.S. Federal Aviation Administration said it is proposing requiring four key design and operating changes to the aircraft.
It would address safety issues seen in two fatal crashes that led to the plane's grounding in March 2019.
The agency's proposed changes include updated flight-control software...
A revised display-processing software to generate alerts...
A revision of certain flight-crew operating procedures...
It also put forward updates in the routing of some wiring bundles.
There are still hurdles, however, before the MAX can fly again.
That includes collecting public comments on the changes for 45 days, and finalizing a new set of pilot-training procedures.
Other regulators in Canada and Europe also have their own concerns.
Given the work required, it is unclear whether U.S. flights will resume before the end of the year.
The crisis over the once top-selling 737 MAX has cost the U.S. planemaker more than $19 billion.
Criminal and congressional investigations are also still ongoing.
