How many in-flight engine shutdowns have you had in your career? For the crew of a General Electric CF34-powered Challenger 604 owned by David Wetherell, the answer would be two. One per engine, over a five-week period, in a brand-new aircraft with about 100 hr TT.

At its triennial meeting in Montreal in early October, the ICAO Assembly–which includes representatives from all 187 ICAO member nations–approved a more flexible approach to the application of aircraft noise regulations.
Flight testing of the Pratt & Whitney Canada PW615F–the engine Cessna selected for the Citation Mustang–got under way in Wichita on April 27. In an unusual move, initial flight testing is being conducted by Cessna on its own CitationJet testbed instead of aboard the engine manufacturer’s test aircraft.
Pratt & Whitney Canada is starting its second month of ground runs of the PW610F, the smallest of the company’s new PW600-series engines and the powerplant selected by Eclipse Aviation for its very light jet. On May 4 the engine achieved its rated takeoff thrust of 900 pounds after five hours of ground testing.
While three companies are competing to market FAR Part 36 Stage 3 hush kits for the Gulfstream II, IIB and III, two–Really Quiet and Stage III Technologies–have been developing their respective systems much longer than either originally planned. Really Quiet could very well be the first to receive FAA certification, which is expected this month.
After some 100 flights, Spirit Wing Aviation of Guthrie, Okla., has completed development testing of its Williams FJ44-powered Learjet 25D and expected to begin about five months of FAA certification flying. The FJ44-2C turbofans replace the Learjet 25D’s original GE CJ610-8A turbojets.
General Electric and Honeywell International formally terminated their merger agreement, four months after European regulators rejected the proposed $45 billion deal. The new agreement, which releases both companies from all merger-related legal actions, ends the threat of Honeywell suing GE for allegedly violating the merger agreement by not pushing regulators hard enough.
First flight of a Williams FJ44-2C-powered Learjet 25D continues to be a moving target as Guthrie, Okla.-based Spirit Wing awaits delivery of the engine nacelles from Nordam. The design of the stainless steel inlets is made more complex by the fact that they must act as radiators to dissipate the 800-deg F heat of the FJ44’s bleed air, which will provide full-time anti-ice protection to the engines.
In a bid to expand its capabilities to service larger turbine engines, Standard Aero has purchased turbine engine component overhauler TSS Aviation of Cincinnati, Ohio, for $65 million. Standard Aero and Landmark Aviation were purchased by Dubai Aerospace Enterprise (DAE) from private-equity firm Carlyle Group last month for $1.9 billion.
Pratt & Whitney Canada’s new PW535E turbofan engine for the Embraer Phenom 300 has reached its full takeoff thrust of 3,360 pounds at the company’s Longueuil, Quebec test facility. Embraer chose the PW535E turbofan in May 2005 to power the Phenom 300.
