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.

Re-engining the Boeing 767

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.

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.

How good is a used 767-300ER? Part 4

Introduction

Jan. 6 2016, ©. Leeham Co: We now finish our series of acquiring a used Boeing 767 aircraft to upgrade a Boeing 757-based long haul service. The 767 went out of favor recently as it has higher fuel consumption per seat than competing aircraft like Airbus A330-200.

With today’s low fuel prices and favorable used prices, a well kept 767-300ER is once again an interesting long haul aircraft. In previous articles, we looked at different aspects of the 767-300ER compared with the A330-200. First we compared the aircraft’s characteristics (Part one), then Cash Operating Costs (Part two) and finally Direct Operating Costs (Part three).

We now finish the series with a revenue and margin analysis. First we establish the competitor’s payload carrying capabilities over a trans-Atlantic network. Then we calculate their revenue capabilities using standard yields (revenue per load unit). The revenue and cost data then gives us the operating margins for the aircraft.

Summary

  • The 757 has the lowest costs but is considerably more limited in its payload and range capability than the 767 and A330. Its lack in capacity is augmented by a lack of cargo handling facilities.
  • The 767 has a cargo handling concept, unfortunately with the wrong container standard, LD2. The alternative is pallet based freight, which works well for the 767.
  • The A330-200 has the best passenger and cargo transporting capability. This compensates for its higher Direct Operating Costs but the low fuel prices keeps the 767 in the hunt.

Introduction

Jan. 4 2016, ©. Leeham Co: Before Christmas we started our Boeing 767-300ER article series around acquiring used twin-aisle 767 aircraft to upgrade Boeing 757-based long haul services. We compared the aircraft’s base characteristics in Part One and then their Cash Operating Cost (COC) in Part Two.

Now we continue by analyzing the Direct Operating Cost (DOC) of the aircraft. This adds capital costs to the other operating costs for the aircraft. As the reason for our renewed interest in the 767-300ER is the attractive prices on the used market combined with low fuel prices, the capital costs are an important part of the overall understanding of the costs for the aircraft.

In our assumptions, the 767 is bought as a 10 year old aircraft and then refurbished. It is then operated on a six year financial lease, as is our 757 that we replace. Our benchmark aircraft, the Airbus A330-200 flying in a mainline airline, was bought new in 2009 and is operated on a 10 year financial lease.

Summary

  • The low capital costs of the 767-300ER makes it cost competitive in the fuel scenarios that are likely within its six year lease period.
  • The 757-200W has fractionally lower direct seat mile costs than the 767, but it has lower capacity and its more limited range reduce its operational usefulness.
  • The A330-200 has the best operational flexibility but its higher capital costs makes it the most expensive aircraft to operate in the period of interest.
  • In a final article, we will add the revenue capability of the aircraft. This is where the A330-200 gets the chance to show if it can cover its higher direct costs with its higher earnings capability, thereby generating more value for the airline.

Introduction

Aug. 31 2015, ©. Leeham Co: After examining the characteristics of the Boeing 767 to serve the market segment that Boeing is studying for its Middle of the Market (MOM) requirement, the 225 passenger/5000nm sector, we will now finish the series by looking at how the 767 can be made economically more competitive.

We will study the influence of improved aerodynamics like Aviation Partners Boeing’s Split Scimitar Winglet for the 767. We will also look at what engine PIPs can provide and also look at what a re-engine could bring.

Finally we examine at what happens when we add crew costs, underway/landing fees and maintenance costs to form Cash Operating Costs (COC) followed by capital costs to form Direct Operating Costs (DOC).

Summary:

  • Boeing’s 767 has the right cross section for passenger transportation in the 225 passenger/5000nm segment.
  • Its wings and empennage are too large, however. We make them work harder by transporting the 767-300ER fuselage and passengers.
  • We also introduce aerodynamic and engine improvements. Still, the fuel consumption per seat mile is considerably higher than modern alternatives.
  • At a Cash Operating Cost and Direct Operating Cost level, the higher fuel consumption has less influence in today’s fuel prices. The result is that the 767-300ER becomes an interesting alternative as long as the fuel price stays low.

Aviation Partners Boeing: next step–scimitar for 757, 767

Introduction

April 14, 2015: Several airlines operate the Boeing 757 across the Atlantic on “thin” routes but sometimes have to do refueling tech stops when high westerly winds

occur.

The 757s are aging, with engine maintenance, repair and overhaul costs increasing under the tightly-controlled contract with Rolls-Royce and Pratt & Whitney.

Some airlines want a “757 replacement.” Boeing and Airbus don’t see a market for “just” a 757 replacement and argue the 737-900ER/9 and A321neo/LR are the replacements. Even these fall somewhat short.

Industry observers and pontificators nonetheless are obsessed with a “757 replacement” (except us—we’ve redefined the replacement as one needed for the 225/5000 Sector [225-250 seats, 5,000 miles] and concluded an airplane very similar to the 767-200 is needed).

Patrick La Moria, EVP and chief commercial officer, Aviation Partners Boeing.

While all this debate is going on, Aviation Partners Boeing (APB) is close to seeking board approval to offer a scimitar option for the 757 that will improve efficiency by about another 1.5%. A scimitar for the Boeing 767 may not be far behind.

Summary

  • Scimitars and the increased range will eliminate some “tech” stop for fuel.
  • Field performance will be better.
  • Low fuel prices and prospect of scimitars (as well as lack of availability of new airplanes) may lead to longer retention of 757s and 767s.
