Introduction

October 31, 2019, © Leeham News: We have looked into what a reengining of the 767 with GE GEnx engines would give over the last two weeks. FlightGlobal wrote Boeing considers reengining the 767-400ER with the GEnx engine to produce a new freighter and perhaps a replacement for the NMA project.

We analyzed the aircraft fundamentals in Part 1, then passenger and cargo capacities in Part 2 and now we finish with the economics of different possible variants compared with the standard 767 and a possible NMA.

Summary:

• The economic improvement of a GEnx reengined 767 is hampered by the new engine's larger size and higher weight.
• After catering for the increased empty weight and drag of a reengined 767, the result puts the project in question.
• A reengined 767 is far from a replacement for the NMA.
