Engine Upgrade Improves Power, Fuel Burn, Throttle Response and Cost of Ownership

Honeywell Adds Five-Year, or 2,500-Hour, Warranty for TPE331-12JRs

Honeywell has extended the warranty to five years or 2,500 hours for the TPE331-12JR turboprop engine, which now powers a dozen Cessna Caravans upgraded by Aero Twin, Inc. and Texas Turbines Conversions, Inc.

“The TPE331 turboprop engine provides up to 30 percent more power, reduces fuel burn by about four gallons an hour, has a faster throttle response, and costs as much as $40 an hour less to operate than the production motor on the Caravan,” said Mike Bevans, technical sales director, Business and General Aviation, Honeywell Aerospace. “The TPE331 now has an even lower cost of ownership on the Caravan with a standard five-year, or 2,500-hour, warranty.”

Engine Delivers Improved Thrust and Range

EBACE, GENEVA, May 4, 2010 — Honeywell (NYSE: HON) announced today that its TFE731-50R turbofan engine will power the Hawker Beechcraft aftermarket retrofit Hawker 800XPR.

In its Hawker 800XPR configuration, the installed engine will deliver 4,660 pounds of thrust.

“The TFE731-50R is certified to 5,000 pounds of thrust and has significantly improved temperature margin, giving our customers an engine with incredible durability, reliability and reduced cost of ownership,” said Rob Wilson, president, Business and General Aviation, Honeywell Aerospace. “Coupled with reduced thrust-specific fuel consumption at cruise and improved climb thrust, the -50R will deliver the performance and reliability that customers of the Hawker 800XPR program want. The engine is delivering mature levels of reliability for Hawker operators.”

On Nov. 20, Honeywell and Hindustan Aeronautics Ltd. (HAL) celebrated 25 years of aerospace collaboration, including production and support of the TPE331-5 turboprop engine. In a celebration event commemorating the partnership, Rob Wilson, President, Honeywell Business and General Aviation; Ashok Nayak, Chairman, HAL; and Anil Gupta, President, Honeywell India entertained a crowd of Honeywell employees, HAL employees and members of the media highlighting the milestone. The celebration began with a traditional lighting of the lamp ceremony and closed with an exchanging of plaques.

By the end of 2009, business jet manufacturers are anticipated to have completed more than 400 conversions of the Honeywell 36-100 Auxiliary Power Unit (APU) to the more quiet and reliable 36-150 series APU.

"With an increase in reliability of almost 50 percent and an associated decrease in the cost of operations, the 36-150 APU conversion has been incredibly popular with Gulfstream and Bombardier business jet operators," said Brian Sill, Vice President of Business and General Aviation Aftermarket. "The 36-150 APU is ten decibels quieter than the 36-100 at the APU engine inlet and because it is less sensitive to surge, the surge valve stays closed in more operating conditions, further reducing the noise signature to make it a good airport neighbor."

The conversion replaces the power section of the APU with a new, ported shroud power section technology that increases air flow while reducing noise significantly.

"The 36-150 conversion is an affordable way to increase an aircraft's value while providing immediate benefits like a more comfortable cabin and lower cost of operations," Sill added. "The conversion includes a no-cost enrollment in our Maintenance Service Plan."

An APU is a high-performance, small gas turbine engine that provides bleed air for main engine starting, pneumatic systems and electrical power for cockpit and galley systems. The Honeywell 36-series APU is the industry leader for auxiliary power in business aviation, with more than 6,500 units delivered. Conversions are scheduled through the aircraft manufacturer.
