Over the next couple of months Garrett/Piedmont Hawthorne/Associated will be closing its engine repair facilities in Long Island, N.Y., Columbus, Ohio, and Springfield, Ill., consolidating these services at its facilities in Augusta, Ga., Houston and Los Angeles. In addition, the company’s Springfield operation will become a “center of excellence” for airframe and avionics work, interior refurbishing and aircraft painting.

News and issues relating to business aircraft turbine engines.
Elliott Aviation of Moline, Ill., has authorization to do full line service and maintenance on the Williams-Rolls FJ44-1A/2C and -2A turbofans used on the Cessna CitationJet and Beechcraft Premier I, respectively.
“The Williams-Rolls authorization is one more step in our continued efforts to provide additional value to our customers,” said company president Wynn Elliott.
Tulsa, Okla.-based BizJet International announced the completion of its first Spey midlife event after becoming a Rolls-Royce-authorized overhaul facility.
Of some 3,572 TFE731-2 and -3 engines on U.S.-registered business jets that would have to get their low-pressure turbine stage 1 disks repetitively checked for fatigue cracks, it is estimated that about 1,900 would need to replace the disks, if the FAA adopts a proposed AD. The directive would essentially mandate compliance with a two-year-old Honeywell Service Bulletin that addresses possible fatigue cracking in the disks.
Hartzell Propeller introduced its own line of de-ice components to support the entire line of Hartzell propellers. Hartzell is marketing its new components as replacements for third-party manufactured parts, including boots, wire harnesses and slip rings. Hartzell boot replacements are under warranty until 18 months or 2,000 flight hours. Other de-ice components are covered for 12 months or 1,000 flight hours.
The first flight-worthy Williams FJ44-3AP engine for the prototype PiperJet has arrived at Piper Aircraft’s factory in Vero Beach, Fla. Engineers are still fine-tuning the design, and wind-tunnel testing continues while technicians manufacture tooling for the prototype. Three to five prototypes will be built.
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.
A new NASA study claims that man-made cirrus clouds formed by commercial jet engine exhaust might be responsible for increased surface temperatures detected in the U.S. between 1975 and 1994.
Climate data shows that cirrus cloud cover over the U.S. has increased by 1 percent per decade, and the report says the rise is likely due to commercial air traffic.
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.
