The Catalyst™ engine has now entered certification testing, where GE Aviation will validate its aerodynamics, mechanics and aerothermal systems. The 1,240 shp-rated engine introduces 79 new technologies to offer higher efficiency, better performance and greater durability than other engines in its class.
With the first engine run and most of the individual component testing completed, early indications show that the Catalyst will meet or exceed all the performance numbers quoted.
The development program of the Denali single-engine turboprop marked a recent milestone with the successful mating by GE Aviation of its advanced Catalyst engine with the MCCAULEY composite propeller at the test facility in Prague. Watch the video produced by GE Aviation on the progress of the Catalyst.
With a jet-like cabin design, dual-channel FADEC and the first clean-sheet turboprop engine in more than 30 years, the DENALI aircraft is sure to disrupt the marketplace. But behind the features and capabilities of the new aircraft is a team of experts invested in both the plane and those who will sit inside.
They call themselves "The Denali Core Team" and their mission is to deliver Textron Aviation's most advanced single-engine turboprop. However, that's where many of their similarities end. From manufacturing to customer service to marketing, the team is packed full of experts from strikingly different areas all working together to break boundaries.
"The best product comes from the best team," stated Ernie Krusbsack, Denali's Program Manager. "There isn't an individual on this team that isn't enthused and engaged about the product."
Krubsack leads the core team, which is fitting considering his history with Textron Aviation. He's been doing program manager work for nearly 20 years, most recently on the Cessna CITATION LATITUDE aircraft. His expertise lies in gathering innovators in many different fields of aviation and fostering an environment where they work in unison.
"It can be difficult," Krubsack said. "But I find it enjoyable in the sense that you have to get into each person's psyche, and you have to understand what makes them tick."
While Krubsack leads the core team, each member of the team represents his or her own division. It's a challenge they don't take lightly.
"I've been interested in taking on the challenge of lead engineer on a program," Manufacturing Engineer Program Manager Jonathan Braaten said. “When this opportunity became available, my supervisor handed me the keys and said, 'Alright, let's see what you've got.'"
Braaten's push for human factors, ergonomics, and cost-effectiveness on the program stemmed from his manufacturing viewpoint. Others, such as David A. Dorner, emphasized the need for quality aftermarket parts and service options for Denali's Customer Service Team.
"Early in the program, we established best practice, maintainability, and reliability goals to ensure reduced labor hours per flight hour," stated Dorner. "We also monitored the associated design attributes for the platform to improve operational availability."
Major aftermarket advances on the Denali aircraft included the implementation of an industry-leading diagnostic system, comprised of both a Central Maintenance Computer (CMC) and a full-time data recorder (AReS). When combined, the CMC and AReS provide indicated causes for crew alerts and advanced troubleshooting, a major boon for Customer Service representatives. Other on-board solutions already incorporated on the aircraft help to minimize specialized tools and test equipment needed for Denali turboprop maintenance.
The team's use of the Maintenance Steering Group (MSG-3) analysis process further highlighted the unique collaboration on the Denali turboprop. Comprised of a steering committee of operators, suppliers, engineering personnel, and FAA representatives, the team involved in the MSG-3 process provided detailed analysis of every system, structure, and zone of the aircraft for scheduled tasking and maintenance interval requirements.
When other Core Team areas step up to support the needs of other departments in the build, it hasn't gone unnoticed. "This engineering team has been amazing. Very, very responsive," Dorner said of the requested changes from Aftermarket. "That's been very exciting."
That balance often revealed itself in gray areas and processes that had to be tested, developed and finally implemented. Much of the responsibility fell under Brad Bednar, the Experimental Project Coordinator.
"I think I'm just comfortable dealing with ambiguity and then learning something new each day and each week. In this role, if you want to stick to one schedule or one way of doing things, you're not going to absorb all the knowledge," Bednar said. "As the plane gets built, you check and adjust your plan seven, ten, twelve times and see what's the best route to move."
"It becomes a big part of your life," Braaten said about the Denali aircraft. "The Denali turboprop is a high priority program for Textron Aviation, so it's a huge but exciting responsibility."
It's been nearly five years of work for many on the Denali Core Team and that time and investment means passion.
"We're all personally connected to the Denali turboprop," IT Senior Specialist Mark Thomas said. "It's more than an airplane for those of us involved. It's a collection of work from tons of people and the relationships that you build."
Dorner equated the project to other legacy designs when he said, "KING AIR turboprops, CARAVAN turboprops, those have been around for a very long time and I fully believe that the Denali turboprop will be the next one of those. It's an advanced turboprop and I believe it will be here for a long time. I think someday I'll be telling my grandkids, 'I was on that team.'"
Braaten added, "We're doing something that's unique. This is a brand-new clean-sheet airplane and when we're done, I can say our team did that. That'll be out there for who knows how long. Long past my lifespan, I'm sure."
For some, it could be their future left seat.
"Because I have my pilot's license and enjoy the plane aspect of this business, with the Denali turboprop, maybe it's something I'll be flying in the future,” Bednar added.
When that moment comes for the Denali aircraft to leap into the air for the first time, this team says it will be emotional.
"Hair tingling. It happens every time," Krubsack said. "Every time I go to a first flight that I've been a part of, it really tingles the hair on the back of your neck and just gives you the enthusiasm that you get about every five years."
Thomas added, "The first flight is that magic moment culminating years of work."
As that moment nears, the Denali Core Team says it wants to highlight one other thing. It's not just the core team behind this aircraft. It's hundreds of employees on various shifts doing any number of duties who are making this innovative dream come alive.
The launch of the DENALI turboprop will, without question, disrupt its aircraft market segment. But designers, developers and engineers at Textron Aviation want to be sure your trips utilizing the new aircraft are anything but disrupted.
Therein lie two solutions - the Maintenance Steering Group - 3 (MSG-3) and the On-board Maintenance and Diagnostics system. Both tools are implemented with reliability and your bottom line in mind.
MSG-3 is a process developed by the aviation industry and regulators worldwide to develop applicable and effective inspection tasks and intervals for an airplane. Rather than servicing an aircraft based on an uninformed calendar, an aircraft receives maintenance due to its carefully-calculated needs. Those involved with the process say Textron Aviation has used the MSG-3 process as a basis for developing scheduled maintenance on new airplane designs since 2005, though the Denali turboprop will be the first single-engine turbo-propeller aircraft that offers it.
The On-board Maintenance and Diagnostics system is comprised of two different types of system recordings - event-driven (CMC) and full-time (AReS II) functionality. These two systems work together to provide a comprehensive monitoring and reporting system that covers everything that happens on the aircraft, spanning from routine to advanced troubleshooting and analytics. Users can see CMC data, AReS data and time-critical fault data in several places once landed, which can also be transmitted to LINXUS, our customer data portal automatically over Wi-Fi. If immediate, in-flight notifications are warranted, users can arrange for the installation of a special Garmin box called the GSR-56.

Piloted by senior test pilot Peter Gracey and chief test pilot Dustin Smisor, the BEECHCRAFT DENALI prototype aircraft, powered by GE Aviation's new CATALYST engine, took off at approximately 8:20 a.m. on November 23, 2021 from Textron Aviation's west campus at Eisenhower International Airport for its first flight. During the 2-hour and 50-minute flight, the team tested the aircraft's performance, stability and control, as well as its propulsion, environmental, flight controls and avionics systems. The aircraft reached an altitude of 15,600 feet and attained speeds of 180 knots. The following is an exclusive cut of the video for Denali Insiders only.
The new Beechcraft Denali turboprop is accompanied by an engine GE Aviation calls “next-generation.” As sustainability becomes a greater focus of aviators across the world, GE Aviation and Textron Aviation are joining together to provide an aircraft that reduces CO2 emissions, increases efficiency and works with Sustainable Aviation Fuel (SAF).
While we are overcome with joy and confidence that the Beechcraft Denali turboprop's first flight was successful, we expected nothing less. Did you know the Denali aircraft's first flight wasn't the first time the GE Aviation Catalyst engine hit the skies? Before our clean sheet aircraft took off for the first time, the Catalyst engine went through hours of rigorous testing in the sky on the tried and trusted KING AIR turboprop. This allowed engineers to go through extensive tests with a single Catalyst engine and prepare it for the big day of first flight.
Here's some behind the scenes video showing the test on the King Air turboprop. You can see the performance was as stellar as we imagined even before the Denali turboprop took flight.
