The U.S. Federal Aviation Administration (FAA) on Wednesday cleared Boeing’s 737 Max to fly again.
The jetliner was grounded for 20 months after two international crashes killed 346 passengers and crew.
The grounded planes will need to be refitted with improvements mandated by the FAA while pilots will need to be retrained in procedures for Max 737 to fly again.
Reports said the model might even get a new name.
And although the FAA has restored Max’s airworthiness certificate, critics say the twin-engine plane’s design is inherently flawed and the plane should not be allowed to fly again.
The Max 737 crashes triggered congressional investigations in the United States and other investigations that revealed shortcomings and even deceit when safety issues arose during the plane’s development.
