Introduction
Sep. 24 2015, ©. Leeham Co: In the second part of our series about comparing and evaluating economic and operational performance of airliners, we look at the parts beyond fuel that make up the Cash Operating Costs (COC) for an airliner.
While fuel consumption, crew costs and aircraft maintenance costs can be evaluated in a way which closely resembles reality, other costs in the COC are too complex to model in their true form.
This is the case for underway or airway fees, landing fees and station fees. Here, just about every country/airport in the world has taken the liberty to invent its own charging principles and formulas. With several hundred different formulae for these charges, the way out is to use industry-accepted approximation for these costs.
Summary:
- We establish how crew cost are modeled for our evaluation missions, taking into account the complex world of work time regulations for pilots and cabin crew.
- We also describe how we handle airframe and engine maintenance costs and how these get allocated to our missions.
- Finally, we describe how the complex underway and landing/station costs are modeled with the accepted approximations these require.

Introduction
Part 3
Sept. 14, 2015, © Leeham Co. It’s only been three months since the Paris Air Show and there have been some significant developments in the world that have impact on commercial aviation:
- Oil prices dropped from about $62/bbl to a low of $38 in mid-August and it’s climbed back to about $46 this week;
- China devalued the Yuan;
- The Brazilian economy has deteriorated and so has the domestic political situation; and
- Some LCC airlines in Asia are feeling the strain of growth and weakening currencies.
We talked with Paulo Cesar, president and CEO of Embraer at the Paris Air Show on some of these topics. We caught up with him Sept. 2 in Seattle, revisiting these topics and talking about more.
Boeing’s 767 revitalized as a MOM stop gap, Part 3

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.

Introduction
Airbus A320neo. Source: Airbus
Sept. 7, 2015, © Leeham Co. Airbus is oversold in its A320 family positions as it transitions from the ceo to the neo, an analysis shows.
The first delivery of the A320neo is scheduled for December. Airbus plans to phase out the A320ceo family over two years (as does Boeing with the 737NG in favor of the 737MAX).
We analyzed the 737NG bridge to the 737MAX last week and concluded Boeing faces a production gap of between 100-200 aircraft, depending on how delivery dates of 737MAXes for Unidentified customers are scheduled. We indirectly received push back from Boeing on this, which we also address in today’s report.
Summary
- Airbus is oversold in 2016 and 2017.
- A gap appears in 2018, but this depends in part how “TBA” delivery dates are allocated for Unidentified customers.
- Boeing says Options and Overbooked orders fill its apparent 737 gap.
- We update our 737 production gap analysis to include Options and find a gap still exists.
- Boeing wants to accelerate MAX deliveries from 2018 into 2017.
Boeing faces 737 production gap: analysis

Introduction
Sept. 2, 2015, (c) Leeham Co. Boeing faces a production gap for the 737, based on an analysis of the delivery streams of the 737NG and the 737 MAX.
There’s a production gap for the Boeing 737 more than 100 airplanes, according to a Leeham Co. analysis. Boeing photo.
While focus of Boeing production gaps has been on the 777 Classic and, to a lesser extent, the 747-8, few have analyzed the production gap for the 737 line. Boeing announced rate increased from 42/mo to 47/mo in 2017, the year the MAX enters service, and again to 52/mo the following year. The company is studying taking rates even higher, to 60/mo, by 2020. Boeing cites a large backlog and continued demand for the 737 for boosting production rates.
But Market Intelligence indicates emerging concerns about the gap.
Summary
- We see a gap of perhaps 100-200 737s in 2017 and 2018, even as the 737 MAX is “feathered” into production of the 737NG.
- Beyond 2018, the apparent gap depends largely on the delivery stream of Unidentified MAX customers accounting for nearly 600 orders identified by the Ascend data base. Boeing lists just over 1,000 Unidentified 737 orders through July (August figures aren’t out yet), sharply higher than the Ascend data base.
- The current low fuel price environment is a concern.
Boeing’s 767 revitalized as a MOM stop gap, Part 2

Introduction
Aug. 31 2015, ©. Leeham Co: Last week we started to look at Boeing’s 767 to see if it can serve the passenger and range space which is not well covered by modern aircraft: the 225 passenger/5,000nm sector. Boeing calls this the Middle of the Market or MOM. Boeing recently said that there is some increased interest for the 767. We analyze why and what can be done to increase any chances of it having a new life as a passenger aircraft.
We started with comparing the 767’s different variants to the most likely MOM aircraft from our series “Redefining the 757 replacement requirement for the 225/5000-sector”. We will now continue and look at the 767 in detail, its strong suits and its less efficient areas. We will also discuss what can be made to address the less efficient areas.
Summary:
- Boeing’s 767 has the right cross section for passenger transportation in the 225 passenger/5,000nm segment.
- It also carries cargo containers, not as efficiently this time. We show what the consequences are.
- Finally the wing is not the slender wing of the modern aircraft. We show what impact it will have on overall efficiency.
- Combined with engines from the 1990s, this gives less than stellar fuel economics. We investigate what can be done about this and how much of an impact it will have in today’s low fuel prices.
Boeing’s 767 revitalized as a MOM stop gap?

Introduction
Aug. 27 2015, ©. Leeham Co: In our Monday article, “Boeing sees healthy future for 767,” Boeing’s spokesperson said, “We are continuing to explore additional capabilities and improvements” for the 767. It was not clear what these improvements were other than a 0.5% engine performance improvement package (PIP) that was introduced earlier in the year. With lower and lower fuel prices, existing aircraft get more and more viable as a stop gap to cover market segments that today are not part of the plans for the OEM’s modern products.
We will therefore examine the 767 deeper to understand what can be improved further and how well such an improved model would serve as a stop gap replacement for the lack of a modern Middle of the Market (MOM) aircraft. We explored how a MOM aircraft should look like in our series, “Redefining the 757 replacement requirement for the 225/5000-sector”.
The 767 has several of the attributes that we found optimal for a MOM aircraft, one having a seven abreast cabin cross section. In the 767 variant that is being produced for the US Air Force tanker program, the 767-200ER, the overall fuselage dimensions are also close to the ones we found desirable for a MOM aircraft.
With fuel now well below $2.00 per US Gallon (about $1.35), we will compare the 767 to our MOM specifications and try to understand where there is a fit and what would needed to be changed to improve the 767’s efficiency so that it could serve as a MOM stop gap. Finally, we will check if such changes can be economically viable in different fuel price scenarios.
Summary:
- Different to the 757,the 767 is still produced for the foreseeable future, thanks to the US Air Force tanker program.
- Boeing 767 is the only produced aircraft that has the desired seven abreast cabin, which we found optimal for a MOM aircraft.
- How does the 767 fuselage and wing compare to the ones we found desirable for the MOM?
- Is the cargo capability of the 767 acceptable for a MOM role?
- We explore the primary characteristics in our first article today. We will go deeper with technical and economical analysis in subsequent articles.
Six year turnover in sale/leasebacks put supply-demand balance at risk
Subscription Required
Introduction
August 24, 2015, © Leeham Co. When airlines like Indigo of India, Air Asia, Norwegian Air Shuttle (NAS) and Lion Air have outstanding orders for Airbus A320s and
Boeing 737s that number in the hundreds, far more than operations and growth appears ready to support, the deals raises the natural question: What are they thinking?
As LNC’s Bjorn Fehrm explained Friday, one aspect of these big orders is to “flip” the aircraft every six or seven years, a time that roughly coincides with the maintenance holiday/warranty period. Sale/leasebacks are used to finance these huge purchases.
The practice is hardly new. The USA’s JetBlue Airlines, Ryanair and others practiced this flip for years.
Carriers like the new LCCs mentioned above not only plan to do so to avoid major maintenance costs, but also to fuel their growth. In the case of Lion Air and NAS, these companies also plan to lease out aircraft to other airlines.
But there remain risks involved for the companies and for the industry.
Summary
- The growing practice of flipping aircraft every six or seven years presents risks to lessors.
- Indigo Airlines has 96 aircraft in service, 430 on order.
- Select LCCs in Asia, Europe, India have 1,000 A320s, 737s on order.

Engine Option version. Pratt & Whitney has about the same market share for the NEO, depending on what month it is, with a large number of orders for which no engine has been selected.
Airbus and Boeing are each studying whether to ramp up production of the A320 and 737 families above the record rates already planned.
In an interview Sunday with Leeham News and Comment in advance of the A320 Final Assembly Line opening here, Enders said studies continue whether to take A320 production rates to 60 a month. Boeing is studying rates of 60-63 a month.
