Might be referring to the rudder problem on the 737 in the 90s.

From Wikipedia:

"A total of 157 people aboard the two aircraft were killed."

"The National Transportation Safety Board ultimately determined that the accidents and incidents were the result of a design flaw that could result in an uncommanded movement of the aircraft's rudder."

The MAX line being pushed on to “not requiring specific training”.

That is this time - the time we're discussing. So what's the other time that makes this not the first time?

Yes, sorry, it was late and I misunderstood your question.
