I'd have to raise the BS flag on this one!
First of all there were zero 121 carrier deaths in 2016, or 2015. Basically the same for 135 operation. The last reported death for scheduled commercial flights was February 2009. US Bureau of Labor Statistics only shows data for 2015 and earlier. General Aviation statistic are higher, but that data includes recreational pilots, who are non professional. Industrialized nations had one death in 23.9 million flights.
Your data also included Flight Engineers. There are so few companies that employ FE's. Not many 727, DC-10/MD11, 747-100, 200, 300's, AB-300 in use.
