Pontifications: Warlick’s Warriors support ALS research
March 27, 2017, (c) Leeham Co.: It wasn’t the kind of presentation usually given at the ISTAT general meeting earlier this month. Peter Warlick, vice president of finance for American Airlines, announced to nearly 2,000 people that he has ALS (Amyotrophic Lateral Sclerosis), more commonly known as Lou Gehrig’s disease.
Peter Warlick
ALS attacks the muscular system and is typically fatal within two-five years. There is no cure.
Warlick actually revealed his condition last year, but I missed the announcement in which American also pledged a $1m donation to ALS research.
Although Pete is only a casual business acquaintance, for me, Warlick’s ISTAT announcement hit home. In 2015, a very close friend and

colleague died of ALS several years after diagnosis. Stan Bump was a neighbor and I served with Stan on the planning commission in the Seattle suburb in which we lived.
CSeries wrapping up London City certification

Introduction
March 27, 2017, © Leeham Co.: Bombardier (BBD) CSeries did the last flights of a six-month London City Airport certification last week. The CS100, when certified for London City, will more than double the available payload/range out of the airport. In fact, it can reach New York direct with 40 business passengers on-board, something it demonstrated when it left the airport for JFK on the Saturday.

The aircraft was designed for this performance level from the outset. By designing the CSeries with engines and aerodynamics for the larger CS300, the smaller CS100 became a stellar take-off performer, providing short-field capabilities for London City and other urban airports.
Despite the design for London City, it took Bombardier six months to certify CS100 for the airport. We spoke to CSeries VP Rob Dewar about the challenges and the changes needed to the aircraft to meet the demands of London City.
Summary:
- CS100 doubles the payload-range performance out of London City Airport (LCY)
- Validation flights by SWISS pilots in the week confirmed CSeries suitability for LCY. SWISS should know; it has flown the CSeries predecessor (BAE 146) for years into London City.
- The adaptation for the airport has not degraded normal performance. CSeries performance is better than announced and brochure performance will soon see its second upgrade.
- To finish of the validation flights, BBD flew the difficult westward leg London City-New York JFK direct, with a payload representing 40 passengers in business class.
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.
easyJet, the Ryanair follower
By Bjorn Fehrm
-March 22, 2017, ©. Leeham Co: easyJet started 10 years after Ryanair, using the same Southwest Airlines derived Low Cost Carrier (LCC) business model.
easyJet has been expanding at the pace of Ryanair over the years, trailing the European LCC pioneer by around 20% to 30% of passengers carried each year.
For the last fiscal year ending 30 September 2016, easyJet carried 73 million passengers between 30 countries, flying 820 different routes.
Is there an NMA gap?
By Bjorn Fehrm
March 21, 2017, ©. Leeham Co: The NMA (New Mid-range Aircraft), or, as it’s called more and more, the Boeing 797, is hot. The potential buyers at the recent ISTAT meeting in San Diego urged Boeing to take the decision and get it done.
At the same meeting Airbus responds, “Any NMA gap is covered. Our A321neo and A330-800 is available and and no new aircraft is needed.”
Time to look at who’s right. Is there an NMA gap or not? Is there a difference in how Airbus’ and Boeing’s product lineups cover the market? Read more
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.
CDB Leasing aims for 500-600 aircraft portfolio

Introduction
March 16, 2017, © Leeham Co.: China’s evolving commercial aerospace and aviation industry has high-profile companies such as AVIC and COMAC, and its expanding supplier based, combined with joint ventures with Western companies is well known.
Less well known is the growth in the aircraft leasing business. Increasingly, Chinese lessors are showing up on the order lists of the Big Four aircraft manufacturers. Still, there remains a bit of a mystery about the lessors and dynamics within China.
LNC spoke with the newly appointed CEO of CDB Leasing during the ISTAT conference last week in San Diego.
Peter Chang has been in the Western leasing business for decades, employed in key positions with Aviation Capital Group, ILFC and Aircastle—usually with responsibility for China.
He was named CEO of CDB in December, a move that was announced during the January Dublin conferences of Airlines Economics and Airfinance Journal. More key personnel announcements were made during ISTAT.
In an exclusive interview, LNC asked Chang about the origins of CDB, other Chinese lessors, the current policy of restricting flow of Chinese cash outside the country, the Boeing 737-10 and the Bombardier CSeries.
Here is this interview.
Spirit AeroSystems, the world’s largest aerostructures company
A feature report.
By Bjorn Fehrm
March 15, 2017, ©. Leeham Co: Spirit AeroSystems is the world’s largest aerostructures supplier, with main facilities in Wichita (KS). I visited Wichita early March and was given a guided tour of the factories. It was a tour of contrasts.
In production hall two, the Boeing 737 fuselages are riveted together in much the same way as the Boeing B-29 Stratofortress was produced there during World War II. “Rosie the riveter” is replaced with a robot, but the hall still has a busy charm.

In another hall, the production is silent. The winding of the Boeing Dreamliner’s forward fuselage from rolls of tape is made with a swooshing sound. There are few people around; the machines rule. Everything is mega large; tape-layers, tools, autoclaves, the lot. Read more
