Honeywell and Pratt & Whitney Canada have agreed to start doing component repairs on some models of each other’s engines. The details of the agreement are still to be formalized, but it is expected that it will cover Honeywell’s TPE331 turboprops and TFE731 turbofans, as well as its 36-100 and 36-150 auxiliary power units. It will also apply to P&WC’s PW100 and PT6 turboprops and its JT15D turbofan.
Orders for the Safe Flight AutoPower automatic throttle for the Challenger 604 have reached 120, the White Plains, N.Y. company announced here at NBAA ’02. The system, which delivers synchronized thrust management from takeoff to touchdown, was introduced to the business aviation community at the 1998 NBAA Convention.
Pratt & Whitney Canada announced last year at NBAA 2000 that it had embarked on development of a new line of turboprop, turboshaft and turbofan engines, the PW600 series, spanning a power range from 1,000- to 3,000-lb thrust (500- to 2,000-shp), and a demonstration program for geared turbofan engine technology.
The Parker Hannifin Aircraft Wheel and Brake Division of Parker Aerospace announced a guaranteed cost-per-brake-landing (CPBL) program for Pilatus PC-12 and PC-12/45 turboprops with Cleveland-brand steel brakes.
Aircraft Braking Systems Corp. (ABSC) was recently awarded contracts for main wheels, carbon brakes and nosewheels for the Dasault Falcon 900EX and Gulfstream IV. The Akron, Ohio-based ABSC already produces braking systems for Falcon 10, 20, and 50 aircraft, and will introduce a brake-by-wire (BBW) digital braking system for the Falcon 900 similar to other ABSC BBW systems installed on six aircraft models.
Sales of pre-owned turboprop aircraft are a little like the old line, “I have good news and bad news. Which do you want first?”
Last year at this time, dealers predicted that the market was facing a rocky ride, with economic storm clouds already on the horizon and the presidential election still not decided. No one had any inkling of just how rocky it was going to become.
Operators of about 1,100 Honeywell TFE731-2, -3 and -4 engines have until December 31 next year to replace fan rotor discs with improved ones under a new Airworthiness Directive (2001-23-09). The AD supersedes two previous directives that required the removal of certain older discs and established life limits on that disc series. Estimated cost for parts is $20,400 per engine.
With the completion of its first run on October 31, Pratt & Whitney Canada initiated testing of its 2,500-lb-thrust PW625F engine demonstrator. The company plans to develop a family of turbofans for light business jets. P&WC claims the PW625F will provide optimum performance and “significantly reduced ownership costs.” The engine is aimed at the market now dominated by the Williams FJ44 series.

Spectrum Aeronautical (Booth No. 1947) has quantified the CO2 that will be generated by its Freedom S-40 and Independence S-33 business jets and compared those to competing jets to see how the Spectrum jets stack up emissions-wise. On a 600-nm flight, the midsize S-40 generates slightly less than 1,500 kilograms of CO2, according to Spectrum, while comparable jets should generate more than 2,000 kilograms to nearly 4,000 kilograms.
