The Honeywell HTF7700L turbofan that powers the Cessna Citation Longitude has received FAA approval, the Phoenix-based avionics and aircraft engine manufacturer announced today. This certification marks the sixth application of the HTF7000 family, variants of which are already in service on the Bombardier Challenger 300 and 350, Gulfstream G280 and Embraer Legacy 450 and 500. Cessna’s Longitude is expected to enter service early next year.


To date, the Honeywell Aerospace HTF7000 family has logged more than 3.5 million flight hours, and is fast approaching the 2,000th production engine delivery in 2018, some 14 years after its first entry into service. According to Honeywell, the HTF7000 family is designed for on-condition maintenance, has line replaceable components that can be removed and replaced using common hand tools and is designed to be environmentally friendly.


“Honeywell’s HTF7000 family continues to lead the way in performance, reliability and cost of ownership as it continues to expand its presence across business aviation,” said Honeywell Aerospace Engines and Power Systems president Brian Sill. “The HTF7700L engine certification for the Citation Longitude aircraft marks another successful milestone for the HTF7000 family, adding to its growing heritage.”
