Honeywell engines have surpassed the 1 million-hour milestone on Bombardier Challenger 300s after seven years in service, the company announced this morning.

More than 300 of the super-midsize business jets are flying with Honeywell HTF7000 turbofans delivering a dispatch reliability rate exceeding 99.9%, the company says. The rate for in-flight shut downs of the 7,000lb thrust (31kN) engine, a key measure of safety, is less than 0.004%.

The HTF7000 received certification by the US Federal Aviation Administration in June 2002, which came four years after programme launch. The Challenger 300, a super-midsize jet, entered service in January 2004.

"Durability and performance are key requirements when first choosing an engine for one of our business aircraft platforms," said Michel Ouelette, Bombardier vice-president and general manager for Challenger aircraft. "The HTF7000 clearly performs to the required specifications."
