Introduction

June 15, 2017, ©. Leeham Co: We continued the comparison of Irkut’s MC-21 and COMAC’s C919 last week with an analysis of the cabins and systems. The week before, we compared project time plans, structures and aerodynamics.

Now we finish with an analysis of the economics of the aircraft.

Summary:

• The MC-21 is the more advanced aircraft of the two. It uses carbon composites for the wings and empennage.
• Coupled with more refined aerodynamics, the MC-21 offers a higher efficiency than the more classical C919.
