Honeywell Aerospace's HTF7000 engine has reached two major milestones: recently surpassing 10 million flight hours and logging 20 years in service. According to the company, HTF7000 engines collectively accumulate nearly 2,000 flight hours every day.
The first HTF7000 engines entered service in 2004 on the Bombardier Challenger 300. The engines also power the Challenger 350 and 3500; Gulfstream G280; Cessna Citation Longitude; and Embraer Legacy 450/500 and Praetor 500/600.
“We’re expecting to build more than 400 HTF7000 series engines in 2024, and as many as 4,500 over the next decade or so as the demand for super-midsize jets continues to grow,” said Honeywell president of engines and power systems Dave Marinick. “In all, we anticipate a production run of close to 8,000 engines over the life of the program. Those numbers are a tribute to the thousands of Honeywell employees—past, present, and future—who contributed to this landmark program. We can all feel enormous pride in reaching this significant 10-million-hour milestone.”
Honeywell senior chief engineer Jeff Aitchison said the engines have gained a reputation for their reliability. “It was the first engine family we designed for on-condition maintenance,” he said. “We also used techniques like accelerated life testing to make components more reliable, and pioneered the use of data analytics to extend maintenance intervals. The engines are easy to maintain on wing.”
