Honeywell has achieved FAA certification for its HTF7700L engine, the model of the highly successful engine family designed specifically for the Cessna Citation Longitude. The certification is a big step toward the certification of the Cessna Citation Longitude, which is powered by two HTF7700L engines. The Longitude is expected to achieve its certification by the end of the year.

The HTF7700L is designed for low emissions and reduced maintenance cost through on-condition maintenance. Periodic inspections and standard maintenance can be done on-wing reducing downtime, which can be very costly to operators. Honeywell also offers a Maintenance Service Plan (MSP) to help operators predict maintenance costs and increase dispatch reliability.

The Honeywell HTF7000 family of engines was first introduced in 2004 and has accumulated more than 3.5 million flight hours. Nearly 2,000 HTF7000-series engines have rolled out of Honeywell’s factory in Phoenix, Arizona. The HTF770L is the seventh engine to be certified in this series. The Longitude is the first Citation to be powered by one of these engines. Prior applications include Bombardier’s Challenger 300 and 350, Gulfstream’s G280 and Embraer’s Legacy 450 and 500.
