Barry Eccleston wants to take Honeywell back into the commercial helicopter business in a big way, while at the same time finding another airframe on which to hang the company’s newly renamed HTF7000 turbofan, which now powers only the Bombardier Challenger 300.

The NTSB wants the FAA to require Pratt & Whitney Canada PT6A-60 starter-generators to be electrically isolated from the rest of the engine, a modification that is already in the works.
Starting with the new Challenger 300 powerplant, Honeywell will designate all future turbine engines with letters to identify the type of propulsion, such as HTF for a Honeywell turbofan, HTP for a turboprop and HTS for a turboshaft. Previously, the powerplant in the Challenger 300 was designated the AS907 (where AS stood for AlliedSignal–the company that bought Honeywell in late 1999 and adopted the Honeywell name).
One of the technologies that Honeywell says promises to revolutionize aircraft design is something known as “more electric architecture” (MEA). This “breakthrough” technology will replace much of today’s heavy and maintenance-intensive pneumatic and hydraulic fluid and power systems, enabling OEMs to design aircraft with lighter, simpler and more reliable “electric” systems instead of miles of tubing, pumps and valves.
Pratt & Whitney Canada is striving to keep fuel burn on target for its PW307A engine, which will power the Dassault Falcon 7X. Based on results from the first series of engine flight tests, the Longueuil, Quebec-based manufacturer is confident it will avoid the fuel-consumption problem it had on the PW308C for the Falcon 2000EX.
Honeywell has delivered the first production TPE331-12JR-701S turboprop powerplant to Aero Twin in Anchorage, Alaska, for its “850 Caravan” re-engine modification program. The 850-shp engine, certified last September, will replace the original 675-shp P&WC PT6 on the big Cessna single. Aero Twin expects to receive an STC for the conversion this spring.
Premier Aircraft of East Alton, Ill., continues to work with Honeywell on an engine upgrade program for the Falcon 50 expected to be completed in the third quarter of next year, several months later than originally planned.
The Aeronautical Repair Station Association filed a complaint with the FAA against Rolls-Royce, alleging the engine maker does not provide basic safety information as required by FARs.
Two recent accidents in icing conditions involving Cessna Caravans have prompted the NTSB to issue more recommendations for the high-wing turboprop single.
Pratt & Whitney Canada (P&WC) opened a distribution center in Amsterdam, eliminating the need for many customers in Europe, the Middle East and Africa to get parts sent from Canada and, in many cases, allowing them to receive orders in less than 24 hours.
