Bjorn’s Corner: Aircraft engine maintenance, Part 4
By Bjorn Fehrm
March 24, 2017, ©. Leeham Co: After covering the maintenance market for single-aisle engines, time has come for the engines used on wide-body aircraft. The engine maintenance for a wide-body engine is a bit different to the single-aisle engine. The difference is caused by the longer flight times for the wide-bodies. This makes the flight time wear a more dominant maintenance driver than it is for the single-aisle engines.
The changes in overhaul work caused by the difference in flight profiles and the lower number of engines in the market (compared to the single aisles) will affect how the overhaul market is structured and who are the dominant players.

Could an NMA be made good enough?

Introduction
March 23, 2017, © Leeham Co.: After showing there exists an NMA (New Midrange Aircraft) gap, the next question follows: Can an aircraft be made for the segment that can carve out a big enough slice to make it a worthwhile effort?
It’s a tough question. Any new aircraft will cost at least $10bn to develop for the airframe alone. To this one shall add the engine development. There exists no suitable engine for such an aircraft. To motivate the investments, the aircraft has to bring a substantial performance improvement compared to existing aircraft. Can it?

We go through the key areas that can bring improvements and check if enough progress can is made until an NMA entry into service in 2024 or 2025.
Summary:
- Existing aircraft are either too little or too much aircraft to fill an NMA role.
- By careful design choices, especially for the fuselage, a new aircraft can achieve the required performance.
Major fleet decisions may not be positive for Airbus, Boeing
Pontifications is off this week.

Introduction
March 20, 2017, © Leeham Co.: There are some major fleet decisions that will probably come down the pike this year at American, Delta and United airlines. Not all of them are going to be viewed positively by Airbus and Boeing.
There is also a serious warning sign emerging from the Middle East that could have serious, negative impacts on Airbus and Boeing.
Summary
- American Airlines doesn’t want its Airbus A350-900s any more. Consolidation with US Airways appears to have made these surplus.
- Delta Air Lines, which so far eschewed any orders for the Airbus A320neos and Boeing 737 MAXes, is understood to be readying a Request for Proposals to be issued this year.
- United Airlines doesn’t want its Airbus A350-1000s any more. Picking up cheap Boeing 777-300ERs appear to have made these surplus.
- Emirates Airlines, reacting to Brexit and Donald Trump’s travel bans, is undertaking a full business review in response to a sharp drop in bookings.
Bjorn’s Corner: Aircraft engine maintenance, Part 3
By Bjorn Fehrm
March 17, 2017, ©. Leeham Co: In the last Corner, we showed graphs of the yearly flight hours for engines on single-aisle aircraft. Now we will deduce the market for engine overhauls from these graphs.
These will show which engines generate a maintenance volume that is interesting for engine overhaul companies and which engines are niche.

Based on the market size, we will then go through how an engine is maintained when new, mature and at end-of-life.
Bjorn’s Corner: Aircraft engines maintenance, Part 2
By Bjorn Fehrm
March 10, 2017, ©. Leeham Co: Last week we started the series how airline turbofans are maintained. We described the typical work scopes and what the intervals were for different single-aisle engines.
Before we can describe the engine maintenance market we must get a feel for the market size for different engine types.

Engine OEMs diverge on technology for next generation

manufacturers have divergent views of the next round of engine development, either for the Middle of the Market/New Mid-range Airplane (NMA) or New Small Airplanes (NSA) coming in the next decade.
Officials of CFM, GE, Pratt & Whitney and Rolls-Royce appeared at the annual ISTAT conference in San Diego yesterday.
PW’s Rick Deurloo, SVP of Sales, Marketing Commercial Engines, had the added task of dealing with the highly-publicized teething issues surrounding its new Geared Turbo Fan engine on the Airbus A320neo.
CSeries trans-Atlantic capability

Introduction
February 23, 2017, © Leeham Co.: We previously described how new generation engines make the Boeing 737 MAX 8 a trans-Atlantic aircraft. The MAX 8 is smaller than the Airbus A321LR, but not the smallest single-aisle with trans-Atlantic capability. This distinction goes to the Bombardier CSeries.
We wrote about the CS100 capability to cross the Atlantic from London City Airport last year. After the article, we received new and improved data from Bombardier. The CS100 can now fly directly to US East Coast on the difficult westward leg with a business cabin of 42 seats. The updated article is here.
When we look at the improved capabilities of the CS300 (announced at Farnborough Air show last summer), this aircraft can also cross the Atlantic with a full cabin of 130 passengers.
Bombardier arranged so we could discuss this deeper with the VP CSeries program, Rob Dewar.
Summary:
- We use our aircraft performance model to compare the CS300’s suitability for long-haul to the Airbus and Boeing competition.
- The aircraft have similar range and seat mile costs. The smaller aircraft have lower trip costs.
- With Rob Dewar, we explored the potential for additional capability for the CS300.

Singapore 777-9 order pressures, but does not kill A380
Feb. 16, 2017, © Leeham Co.: Last week’s order by Singapore Airlines for 20 Boeing 777-9s and 19 Boeing 787-10s immediately was viewed by some as the death

knell for the Airbus A380.
The 777-9 order would start the final spiral down for the A380, some contend.
This overstates the case and misunderstands the nature of the order.
The A380 is in trouble, there no doubt about that. The 777-9 is putting pressure on the A380. There’s no doubt about this, either. But the contention the Singapore 777-9 order sends the A380 on a death spiral is wild fantasy.
An Airbus official appears today at the annual conference of the Pacific Northwest Aerospace Alliance (PNAA) in Lynnwood (WA). Undoubtedly, he will maintain the party line that the future of the A380 is solid. This, too, overstates the case. There can be a future for the airplane, but some major decisions must be made.

viewpoint, is the best in class.
The MC-21 has a wider fuselage than the A320 (which is wider than the 737). Seats and the aisle are the widest in the class. The overhead bin space is plentiful.
But the airplane is hampered by its environment: Russia itself.
