Few orders announced today at Singapore Air Show
Feb. 3, 2026, © Leeham News: There were few orders announced today at the Singapore Air Show.
Boeing and ATR were the only announced commercial orders. Embraer revealed a previously announced order for the C-390 tanker-transport. And that was it.

By Tom Batchelor
Jan. 19, 2026, © Leeham News: Having announced it was abandoning near-term development plans for a Short Take-Off and Landing (STOL) variant 12 months ago, ATR begins 2026 confident about its position within the turboprop market and with a deeper focus on hybrid technology.
As the only player in this corner of the regional aircraft segment following the withdrawal of De Havilland Aircraft and the Q400 (now the Dash 8-400) from production, ATR has pinned its hopes on next-generation propulsion while also working with Pratt & Whitney Canada to improve the thermal efficiency of the latest-generation PW127XT engine, which powers both the ATR 42-600 and 72-600 aircraft.
The PW127XT is already delivering significant benefits, including up to 20% lower maintenance costs, extended time on wing, and at least 3% improved fuel efficiency compared to previous models.
EU Awards €945 Million to 12 ‘Clean Aviation’ Projects

Clean Aviation Joint Undertaking funds further R&D for decarbonization efforts
By Hanneke Weitering • Science & Technology Editor
Sept. 12, 2025, (c) AIN: The European Union’s Clean Aviation Joint Undertaking has awarded €945 million ($1.1 billion) in government funding to 12 projects aimed at decarbonizing commercial air travel, the organization announced this week. Award recipients for this third funding round, which followed a call for proposals in February, include several major aerospace manufacturers who are developing novel aircraft and propulsion concepts.

According to the governing board of the Clean Aviation Joint Undertaking, the selected projects could reduce greenhouse gas emissions for commercial aviation by no less than 30% over the next 10 years. Award teams will begin work under their Clean Aviation contracts in early 2026 and are expected to flight-test their creations in 2028 and 2029.

Heart Aerospace’s revised ES-30, Part 2

By Bjorn Fehrm
October 17, 2024, © Leeham News: We analyze Heart Aerospace’s latest evolution of the hybrid ES-30 (bottom aircraft in the picture), which replaces the original battery-based 19-seater (top aircraft) and the original ES-30 (mid aircraft).
The latest version, presented in spring 2024, is a parallel hybrid, putting gas turbine turboprop engines outside the electric motors. What are the advantages of the parallel hybrid version, and will it make the Heart ES-30 project more likely to succeed?
We use our Aircraft Performance and Cost Model (APCM) to understand the design choices and the costs involved.
Summary:
- The latest revision of the Heart Aerospace hybrid electric aircraft, the ES-30, takes the hybrid architecture from a serial to a parallel system. It simplifies the architecture.
- Does the revised ES-30 make airline operational sense? We analyze this using our Aircraft Performance and Cost Model.
Bjorn’s Corner: New engine development. Part 10. Airframe integration
By Bjorn Fehrm
May 24, 2024, ©. Leeham News: We do an article series about engine development. The aim is to understand why engine development now has longer timelines than airframe development and carries larger risks of product maturity problems.
To understand why engine development has become a challenging task, we need to understand engine fundamentals and the technologies used for these fundamentals.
In the last Corner, we looked at the nacelles used for a turbofan engine and for an open-rotor engine. Now, we go one step further and look at the integration of modern engines on an airliner.

Outlook 2024: Can ATR finally achieve its production target?
By Judson Rollins
Jan. 15, 2024, © Leeham News: For the second year in a row, ATR fell short of its stated production targets.
ATR delivered just 25 new aircraft in 2022 and 35 in 2023. The latter was five short of its stated target. In early 2023, the manufacturer said supply chain and staffing shortages were the two main reasons for its 2022 shortfall. It has not yet discussed what went wrong last year.
At last year’s Paris Air Show, ATR said it wants to deliver 80 aircraft per year by 2026. However, this seems unrealistic given the OEM’s current order book of 176 aircraft, according to recent data viewed by LNA.

Summary
- Turboprop demand forecasts seem questionable.
- ATR is delaying its timeline for a new eco turboprop.
- Progress continues on a future STOL variant.
Paris Day Two: Air India finalizes earlier deals; Embraer, ATR announce orders
By Bryan Corliss
June 20, 2023, © Leeham News – While Monday’s news from the Paris Air Show was dominated by the one big Airbus order from Indian carrier IndiGo, Tuesday saw a host of smaller deals announced by OEMs, airlines and leasing companies.
IndiGo rival Air India also announced it had finalized its massive 470-jet order from February, which it had split between Boeing and Airbus.
While there was a significant volume of deals announced Tuesday, in many cases, they were formal announcements of deals that OEMs already were carrying on their order books.
- Air India finalizes Boeing, Airbus orders
- Boeing lands orders from airlines, lessors
- Airbus reveals new orders and buyers in previous deals
- Embraer and ATR announce first deals of show

First flight of Universal Hydrogen Dash 8 opens new era, company says

March 6, 2023, © Leeham News: Universal Hydrogen (UH2) last week took off with its demonstrator aircraft for what it believes is the beginning of a new era.

The Dash 8-300 took off from the Moses Lakes (WA) airport at 8:41 am on March 2 for a short flight circling the former US Air Force Base, now called Grant County International Airport. On one circle, the test pilots throttled back the Jet A-fueled Pratt & Whitney PW123 engine, flying on the No. 2 electric motor, powered by hydrogen fuel.
Thus, UH2’s Dash 8 became the second largest plane (after the Soviet-era Tu-155) to fly on hydrogen and the first to fly solely on clean energy given that the No. 1 engine was at idle.
LNA previously reported details of UH2’s airplane plans.

How UH2 moves forward is detailed below.
Summary
- UH2 raised $100m. Another $200m-$250m is required to bring the aircraft to market.
- UH2 has 247 orders and commitments.
- ATR-72 will be the first H2-powered airliner to enter service. The Dash 8-300 will follow.
- A fueling company, not an airplane company.
Outlook 2023: Turboprops: Embraer and De Havilland look to future, leaving market to ATR

Jan. 9, 2023, © Leeham News: Turboprops should be having a moment, given all the concern about how the aviation industry is contributing to climate change. Want to cut your fuel burn by 45%? Just retire your fleet of 70-seat regional jets and replace them with turboprops.
Yet even with concerns over the environmental (and monetary) costs of operating regional jets, there hasn’t been a big move toward turboprops. In December, Embraer announced it was putting the development of a 70-to-90-seat turboprop on hold. The reason: Suppliers can’t provide it with components (meaning engines) that will provide enough of a performance increase to make a new plane worthwhile.
Meanwhile, the orphaned De Havilland Dash-8 – now owned by a rebranded De Havilland Aircraft Canada – has been out of production since mid-2021.
That leaves the Franco-Italian consortium of ATR as the only OEM likely to deliver any turboprops to airlines in 2023, 2024 – maybe even beyond.
That could change by the end of the decade, however. Embraer is working on a hybrid-electric aircraft that could be ready as soon as 2030 in 19- and 30-seat versions. And a rebranded De Havilland Canada is taking steps to restart production of the Dash-8 at a new factory site in Alberta.
Summary
- Embraer focuses Energia on two models
- ATR working to certify STOL version of ATR42
- Can Dash-8 come back with new company, factory, workforce?

By Bjorn Fehrm
Dec. 22, 2022, © Leeham News: Last week, we wrote about Universal Hydrogen’s (UH2) plans to fly a hydrogen-fueled demonstrator aircraft in early 2023, followed by a certified conversion kit for an ATR72 airliner mid-decade.
The plans for the ATR72 hydrogen conversion are at an advanced state. As the first publication, we can describe the overall design and the technical details. The ATR72 implementation brings improvements in several areas compared with what’s been revealed before.

Summary:
- The target ATR72 conversion improves hydrogen capacity and handling compared to earlier concepts.
- The influence on the ATR seating capacity is reduced due to more efficient packaging on the aircraft.
