Safire Aircraft has selected Keith Products to supply the air conditioning for its very light jet, which is currently under development. The vapor-cycle system will be standard equipment on the six-place twinjet. Miami-based Safire also named Barry Controls to provide vibration isolators and mounting structure for the airplane’s two Williams International FJ33 turbofans.
The ranks of small business jets are about to swell with the imminent buildup of new sub-10,000-pound jets certified to FAA Part 23 regulations. Priced from $1.5 to $4.5 million, these jets include the newly certified Cessna Mustang and Eclipse 500, and the in-development Adam A700, HondaJet and Embraer Phenom 100.
Brian Rowe, former head of GE Aviation, died February 22. He was 75. Rowe joined GE in 1957 and later led the CF6 engine program. He was named head of GE Aviation in 1979. Rowe launched the CF34 turbofan for business and regional jets, the F110 for the F-16 fighter and the CF6-80C2, which powers the Airbus A300/A300-600/A310 series, the Boeing 747-300/400, MD-11 and Lockheed Martin C-5.
Premier Turbines, a division of Dallas Airmotive, has added -20, -40 and -60 models to its TFE731 Core Zone Inspections (CZI) program. As a result, the company now offers CZIs on all TFE731 turbofan engines. Neosho, Mo.-based Premier, a Honeywell authorized heavy maintenance facility since 1996, has also modified an engine test cell to support this program.
The advent of very light jets has prompted an FAA proposal to require that all new certification projects for turbofan-powered airplanes of 6,000 pounds or less mtow undergo function and reliability testing similar to that which has been required for larger fanjet-powered airplanes. F&R testing would add complexity, time and cost to new-design projects. The new requirement would not apply to developmental projects already under way.
Williams International of Walled Lake, Mich., expects to receive FAA certification soon for two of its new turbofan engines. U.S. approval is anticipated this quarter for the FJ33, a 1,200-pound-thrust engine that has been selected to power several very light jets still under development, including the Adam A700, Safire Jet, Diamond D-Jet and Aerostar FJ-100.
At General Electric, the official corporate slogan is “Imagination at work.” At Honda, it’s “The power of dreams.” The two companies announced last month they have merged them in an alliance to develop, certify, market and support Honda’s 1,670-pound-thrust HF118 turbofan. The result could be one of the most innovative global alliances in business-aviation history.
Honeywell’s small heavy fuel engine (SHFE), in development since 2003, “will change the game for turboshaft engines in the future,” predicted Ron Rich, the company’s director of advanced aerospace technology.
Few sounds are louder than a jet aircraft at takeoff.
The decibel level of a climbing jet engine at full power can be higher (140 dB) than that of a chain saw (110 dB) or ambulance siren (120 dB), according to the National Institute for Occupational Safety and Health.
But relief may be a toggle away, if recent university research finds its way into aircraft cockpits.
The FAA issued an emergency AD last month to all owners and operators of GE CF34-3A1, -3B and -3B1 turbofans after investigators found an electrical arc-out defect in the fan disk of the engine that broke apart during a Mesa Airlines revenue flight on January 25.
