DREW GRIFFIN, CNN INVESTIGATIVE CORRESPONDENT (voice- over): Former Boeing operations analyst, Rick Ludtke, says during development of the 737 MAX, Boeing had a mandate, make sure any changes to the plane would not require additional pilot training in a simulator.</s>RICK LUDTKE, FORMER BOEING OPERATIONS ANALYST: Unprecedented. Never happened in the past that I'm aware of. We were very uncomfortable with this.</s>GRIFFIN: Ludtke says Boeing managers told him they even sold the plane to Southwest Airlines with a guarantee, a rebate of $1 million per plane if simulator training was required. The flight control analyst says the demand to avoid simulator training, known as Level D, took over design of the aircraft.</s>LUDTKE: Throughout the design iteration, all the status meetings with managers, that was something that was always asked, you know, are we threatened, are we risking Level D. If you are, you have to change it. I think, philosophically, it was the wrong thing for the company to do, to mandate such a limitation. To strongly avoid it makes sense. But to prevent it, I think you can see the line from that to these accidents.</s>GRIFFIN: Federal investigators are now trying to determine if Boeing's cost-saving moves could somehow lead to criminal charges. (on camera): Both Boeing and Southwest Airlines refused to comment on their business deal that was referred to in this piece. But in the meantime, we're learning what is causing the delay in getting Boeing's software fix to the FAA. It was supposed to be sent last week, but CNN has learned there was a glitch in integrating the software with other Boeing programs, which has now caused a delay.

Just ahead, President Trump says he wants former presidential candidate, Herman Cain, for a seat on the Federal Reserve. Is Cain the right man for the job? That's next.
