Gulfstream G250 Flight Test Engines Flying

Embraer Legacy Engine Passes Primary Design Review

EBACE, GENEVA, May 4, 2010 -- Honeywell (NYSE: HON) today announced its HTF7000 engine fleet has surpassed the 700,000 fleet-hour milestone while delivering 99.95 percent reliability. More than 550 engines are now in service on the Bombardier Challenger 300 aircraft.

The first two HTF7000 engines have successfully completed analytical core zone inspections (overhauls) – a requirement for validation of “on-condition” maintenance service. More than 30 other HTF7000 engines have completed hot section inspections with no major issues.

The first HTF7250G flight test engines for Gulfstream’s new G250 aircraft were delivered late last year and have now accumulated more than 150 hours of flight testing on two G250 aircraft with no issues. Prior to delivery to Gulfstream/IAI, the HTF7250G engine underwent rigorous development testing including endurance testing equivalent to 4,000 flight hours and calibration on Honeywell’s Boeing 757 flying test bed. Engine certification is planned for later this year.

“We continue to invest heavily in new technologies and our engine development programs to satisfy our customers,” said Rob Wilson, president, Business & General Aviation, Honeywell Aerospace. “Low emissions were a key construct element when we began designing the HTF7000 nearly ten years ago. We are continually updating our engine technology tool box and our

SABER 1 combustor is addressing market expectations for low emissions, light weight and high thrust.”

The HTF7500E engine for Embraer’s all-new Legacy 450 and Legacy 500 aircraft successfully completed critical design review and core engine testing in 2009. HTF7500 development engine testing will start mid-2010 with certification planned for 2011.

Honeywell’s technology demonstrator engine, the Tech7000, continues component testing to evaluate new coatings, alloys, seals and combustion technologies for next-generation engines. This testing focuses on hot and cold section hardware that could be deployed in future turbofan or turboprop engines in different power classes.
