No. The 73-Max is. There is nothing a matter with it. I am rated on the 738 as well. 24 in our fleet and 27 in South West's fleet. Not one issue with thousands of hours on them. Not to start another thread with the question, Doug.
Eric: I was on staff at Chino Air Museum. I love vintage aircraft, especially prop-driven early fighters. Your Mod 17 is absolutely beautiful.
