The Federal Aviation Administration has uncovered a possible new risk in the Boeing 737 MAX after a series of simulator flights, sources familiar with the issue revealed to Reuters.

Details: In simulator tests for Boeing's latest software fix, government pilots realized that a microprocessor complication could result in the nose of the plane being thrust downward. It remains unknown whether this played a part in one or both of the 737 MAX crashes.

  • Sources indicated that Boeing engineers are trying to gauge if reprogramming the software would present a solution, or if it's necessary to restore the microprocessors on each 737 MAX aircraft, CNN reports.

Why it matters: This latest FAA discovery could delay the 737 MAX's return to flight service. The aircraft has been grounded since March after two crashes resulted in 346 fatalities. Early investigative reports indicate that a new stabilization system known as MCAS pushed the noses of both planes sharply toward the ground. Boeing has announced a software fix that might limit the negative impact of MCAS, per CNN.

  • An FAA spokesperson told CNN that its investigation "is designed to discover and highlight potential risks," and that they "recently found a potential risk that Boeing is required to mitigate."

What's next: Boeing isn't planning on another certification test flight until July 8 at the earliest, sources told Reuters.

Trump pushes to expand ban against anti-racism training to federal contractors

President Trump announced late Tuesday that the White House attempt to halt federal agencies' anti-racism training would be expanded to block federal contractors from "promoting radical ideologies that divide Americans by race or sex."

Why it matters: The executive order appears to give the government the ability to cancel contracts if anti-racist or diversity trainings focused on sexual identity or gender are organized. The memo applies to executive departments and agencies, the U.S. military, federal contractors and federal grant recipients.

Louisville Mayor Greg Fischer declared a state of emergency Tuesday "due to the potential for civil unrest" ahead of Kentucky Attorney General Daniel Cameron's expected announcement on the Breonna Taylor case.

Of note: Louisville has witnessed more than 115 days of protests over the police killing of Taylor, an unarmed Black woman, with calls for all the officers involved to be charged.
