OSHKOSH AIR SHOW,-- Honeywell (NYSE: HON) announced today that its TPE331-12JR turboprop engine has received Federal Aviation Administration installation approval for Cessna’s 208 series aircraft.
Working with Aero Twin in Anchorage, Alaska, Honeywell’s TPE331-JR is intended as an aftermarket replacement of the existing powerplant on Cessna Caravan 208 series aircraft. Aero Twin plans to provide complete retrofit kits, installation and support services.
“An operator choosing to retrofit their Caravan with Honeywell’s TPE331-12JR will be able to more efficiently utilize the broad capability of the airplane,” said John Bolton, Vice President, Business and General Aviation Aftermarket Honeywell Aerospace. “Amphibious Caravan operators will see improved takeoff performance, usually about a 12 – 14 second water run at 8,360 pounds gross weight with our TPE engine, compared to the nearly thirty-seconds required for a water takeoff at 8,000 lbs with the original powerplant. Operators will appreciate the instantaneous power response delivered by TPE engines.”
The Honeywell TPE331 engine, which was originally developed for the CASA 212 series 400 aircraft, has been in operation for 12 years and enhances the performance and capability of the Cessna 208. The TPE331-12JR provides the following advantages to Cessna 208 operators:
* ~ Cruise of 168 KTAS at 8,000 ft. at 75% power on 386 pph fuel
* ~ Cruise 186 KTAS at 20,000 ft. at 77% power on 318 pph fuel
* ~ Enhanced takeoff performance
o ~ 24% shorter at sea level
o ~ 23% shorter at 6,000 ft.
o ~ 19% shorter at 10,000 ft.
* ~ Improved payload and range
* ~ Up to 4.4 percent lower fuel burn
* ~ Improved rate of climb
o ~ 23% improvement at sea level
o ~ 33% improvement at 12,000 ft.
o ~ 81% improvement at 20,000 ft.
Aero Twin, based in Anchorage, Alaska has led the Cessna Caravan engine conversion and expects to re-engine a significant percentage of the worldwide Caravan fleet. Working with Honeywell, Aero Twin installed a 1,060 SHP TPE331-12 flat rated to 850 shp, driving a four blade Hartzell propeller.
Since entering service in 1965, 13,000 TPE331 engines have been shipped on 40 different applications for regional airlines, utility, business and general aviation and agricultural aircraft around the world. Honeywell continues to ship new TPE331s for various new applications and offers upgrade kits for every key TPE331 model.
Approximately 1,200 Cessna Caravan 208 and 208B models are in service and could benefit from the engine retrofit program.
