Introduction
Sept. 14, 2017, © Leeham Co., Montreal: The prospect of a clean-sheet design turboprop to replace the Bombardier Q400 and ATR series likely has moved to the right by two to three years,

and the total market remains small, but Pratt & Whitney Canada is forging ahead with development of the next generation engine.
- Update: Embraer is considering reentering the turboprop market, reports The Wall Street Journal.
The goal is to reduce fuel consumption by 15%-20% compared with today’s ubiquitous PW127 and PW150, which continue to see reductions in fuel burn through product improvement packages.
Frederic Lefebvre, VP-Marketing for Regional Airlines, now sees development of the new turboprop slipping to 2022-2026 compared with previous forecasts of an EIS in 2020-2023.
Summary
- The Next Generation Regional Turboprop (NGRT) has major challenges to improve upon the current generation of engines.
- PWC sees a much larger market for a 90-seat turboprop than others.
- Emerging markets key to new opportunities.
Pontifications: DAE acquires AWAS, moves up in lessor status
By Scott Hamilton
Aug. 21, 2017, © Leeham Co.: Commercial aviation in the Middle East may be having its severe challenges right now, but over the weekend a major step forward took place.
Dubai Aerospace Enterprises over the weekend completed its acquisition of lessor AWAS. The combined companies will do business under the name DAE Capital.
It’s a milestone for both companies.
Bjorn’s Corner: Electric aircraft, Part 8
By Bjorn Fehrm
August 18, 2017, ©. Leeham Co: In this Corner, we will finish the design of the hybrid propulsion system for our 50-seat regional turboprop. We use the ATR42-600 as a reference, as before (Figure 1).
We found an acceptable redundancy concept in the previous Corner, with an APU+generator+battery as backup power source. Now we will finish the design of the hybrid propulsion chain and compare with the original turboprop propulsion.

Bjorn’s Corner: Electric aircraft, Part 7
By Bjorn Fehrm
August 11, 2017, ©. Leeham Co: In this Corner, we will design the hybrid propulsion system for our 50-seat regional turboprop. We could see in previous Corners that we can’t use batteries as a backup for our gas turbine core and main generator.
The battery gets too heavy as the specific power weight of a battery is simply too low. We will now design a hybrid power chain with a different redundancy concept.

Bjorn’s Corner: Electric aircraft, Part 6
By Bjorn Fehrm
August 03, 2017, ©. Leeham Co: In our search for an electric regional aircraft configuration, we found that a jet aircraft requires too high power levels. The higher speeds of a jet aircraft take the power levels beyond what we can handle with an electric hybrid propulsion system.
Our ambition is to transport 50 passengers on a regional network. For networks which have sectors around 200-300nm, the turboprop is the preferred regional aircraft. We will now re-direct our hybrid regional aircraft project to this market segment.

Pontifications: JADC 20-year forecast: VLA, NMA and other data
By Scott Hamilton
July 24, 2017, © Leeham Co.: The Japan Aircraft Development Corp (JADC) just published its 2017-2037 jet and turboprop forecast. JADC forecasts a demand for 33,336 jet airliners and some 2,000 turboprops.
JADC is partly owned by Mitsubishi, which is developing the MRJ70/90 and which is on several Boeing programs.
I like the JADC forecast because it segments the seating categories in more detail than Airbus and Boeing and somewhat differently than Bombardier and Embraer.
I also view JADC as having less of an axe to grind than the Big Four OEMs.
A couple of quick take-aways:
Bombardier optimistic about China

Introduction
June 5, 2017, © Leeham Co.: Bombardier’s activities in China, where the fuselage for the CSeries is co-produced, have been at a standstill.
None of the Memorandums of Understand or Letters of Intent have been converted to firm

orders. A recent news report suggested renewed talks between COMAC, China’s commercial aircraft enterprise, and Bombardier over acquisition of the CSeries program
LNC sat down with Fred Cromer, president of Bombardier Commercial Airplanes, at the annual general meeting of IATA to discuss these and other issues.
Summary
- An update on the COMAC-CSeries relationship.
- An update on the slow-selling Q400 and CRJ programs.
- An update on the oft-discussed CS500.
