The fleet was grounded for nearly 2 years while Boeing fixed the design flaw and applied the fix to the existing airframes. So they're probably OK now. The whole point of the MAX program was to get a few more years out of a 1960s design with a couple tweaks. Hopefully all the tweaks that cause the plane to dive into the ground are fixed now, simply because there can only be so many tweaks.

I enjoyed this snippet from Wikipedia:

> In March 2022, there were rumors that Boeing would request an exemption from the U.S. Aircraft Safety and Certification Reform Act of 2020, a safety reform law passed in response to the MAX crashes. The act requires airliners to be fitted with an engine-indicating and crew-alerting system (EICAS) if type certificated after December 31, 2022. [...] In December 2022, the U.S. Congress agreed on a bill allowing Boeing to certify the MAX 7 and MAX 10 without EICAS, but it must install a third angle-of-attack sensor in all 737 MAX types as previously demanded by European and Canadian regulators. The company also must install a switch to disable the stick shaker, which distracted pilots during the MAX crashes. Boeing would have to retrofit these design changes to all 737 MAXs already delivered in Canada, Europe, and the U.S. within three years of MAX 10 certification.

This all sounds like a great idea to me. What could go wrong?
