February 1, 2024, © Leeham News: We have been looking at a re-engine of the 767, a move that Boeing is considering to avoid a production stop after 2027. The present 767 engines don’t pass emission regulations introduced by the FAA, EASA, and other regulators for production and delivery beyond 2027.

We used our Aircraft Performance and Cost model to look at the economics of the original 767 Freighter versus a re-engined one before Christmas. Now, we install a passenger long-range cabin and look at the per-passenger mile economics of a re-engined 767-300ER versus the original version.

Summary:

• New, more environmentally friendly engines would give the 767-passenger version better fuel economics.
• The higher the engine maintenance costs of the new engines make the Cash Operating Costs difference between the existing 767-300ER and the new version small.
