December 14, 2023, © Leeham News: We are 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 FAA, EASA, and other regulators for production and delivery beyond 2027.

We have described the history of the 767 and the key data of the different variants in last week's article. Now, we look at what airframe modifications are necessary to house more efficient engines and what consequences these bring.

Summary:

• New, more environmentally friendly engines for the 767 mean changes to the landing gear and structures to house larger and heavier engines.
• For the payload capacity to stay the same a deeper grab in the 767-400 toolbox is necessary than just adopting the landing gear.
