Honeywell HTF7000 Fleet Nearing 250,000 Hour Mark


More than 290 HTF7000 Engines In Service

NBAA, ATLANTA.- Honeywell (NYSE: HON) announced today that its HTF7000 turbofan engine fleet has accumulated more than 245,000 hours of operation and more than 152,000 cycles since entering service.

“The engine dispatch reliability since entering service is more than 99.95%,” said Ben Driggs, Vice President Marketing, Business and General Aviation. “In the last 12 months, with more than 290 engines in service, Honeywell’s HTF7000 has accrued more than 115,000 engine hours in service and the engine fleet is validation that the HTF7000 is one of the most reliable turbofan engine to enter service in business aviation.”

The high time engines have accumulated more than 4,000 hours of operation and two fleet-leader engines have completed comprehensive analytical inspections as part of the scheduled threshold sampling program.

“The HTF7000 is proving it is truly an on-condition engine,” Driggs said. “Sixteen engines have completed routine hot section inspections and have been returned to service as scheduled. More than 500 possible repairs for the engine and LRU components have been written and validated. Honeywell’s case-based troubleshooting tool has more than 2,000 maintenance scenarios loaded for use by the service network.”

Honeywell is supporting the fleet with operator information wires, service information letters, service bulletins and familiarization training. In addition, Honeywell has deployed HTF7000 field service engineers globally to actively support the engine. Honeywell is also providing HTF7000 propulsion training to its global network of Business Aviation field service engineers, to ensure it meets the future requirements of the rapidly growing fleet.

Currently eight “flight line” and 12 “line service” centers, including four in Europe, are tooled, trained, and in operation to support the growing fleet of HTF7000 engines.

The HTF7000 had already completed more than 30,000 hours of development and certification testing at entry into service. The propulsion system had 50,000 hours of control system testing and 4,000 thrust reverser cycles. Honeywell’s HTF7000 propulsion system includes the engine, nacelle, and thrust reverser.
