Introduction

October 17, 2019, © Leeham News: FlightGlobal writes Boeing is investigating re-engining the 767-400ER with GE GEnx engines to produce a new freighter and perhaps a passenger aircraft as a replacement for the NMA project. Development costs would be lower and it would be easier to get a business plan which closes for the upgraded 767 than for the NMA.

We commented on the idea earlier in the week and here follows a technical analysis of what re-engining the 767 would bring.

Summary:

• The 767 is 40 years old in its base design. We look at the fundamentals to understand the trades involved in extending its life with new engines.
• We also compare the 767 technologies with those for the NMA to understand the compromises of an updated 767RE compared with a clean sheet NMA.
