December 7, 2023, © Leeham News: We wrote last week that Boeing is considering re-engining the 767 to avoid a production stop after 2027. The 767 is still an interesting aircraft for companies flying cargo and for the US Air Force, which is taking delivery of the tanker version KC-46A for years to come.

The problem is that all the 767 versions are using engines from the 1970s (GE CF6, PW4000, RB211), and as the FAA has accepted the ICAO emission rules from 2017, the production of the 767 with these engines has to stop after 2027. As reported last week, Beoing is looking at re-engining the 767 to avoid a production stop.

We use our Aircraft Performance and Cost Model (APCM) to look at the different possible configurations with new engines and model their performance data and operating economics.

Summary:

• The Boeing 767 needs new engines if it shall be produced after 2027.
• While the engine candidate is clear, the rest of a re-engined 767 can be configured in several ways. We look at what different configurations bring in operational performance.
