On November 28, a Flight Options Beechjet 400A experienced a double engine flameout at FL380 while on a positioning flight. The NTSB said the crew made two unsuccessful restart attempts before declaring an emergency and deadsticking the airplane safely to Jacksonville International Airport, Fla.
When engine maker Pratt & Whitney opened its first machine shop in a tobacco warehouse in Hartford, Conn., 80 years ago last month, former Wright Aeronautical president Frederick Rentschler probably could not have imagined how popular, and ubiquitous, the company’s engines would become.
Spirit Wing Aviation of Edmund, Okla., said it now expects to receive STC approval for its $2.2 million SpiritLear–a re-engined Learjet 25–in the first quarter of next year. Last year, the company expected certification this past summer.
A new powder-metal turbine disk that Honeywell calls Alloy 10 might show up soon in an engine near you, according to Ron Rich, director of advanced technology development for Honeywell Engines, Systems and Services.
Turbine engines are extremely reliable and many business jet pilots go through their entire careers experiencing engine failures only during simulator training. But in mid-July, two Beechjet 400A pilots found out what it’s like to lose not just one engine in flight, but both of them. Fortunately for them and their seven passengers they were able to get one of the light jet’s engines restarted during the descent.
In the rating codes chart in AIN’s 2004 product support survey (August, page 20), the overall average shown for Honeywell (Allied Signal/Textron Lycoming) turbofan engines should be 5.592. The value is incorrectly given as 6.592. Also, the overall average for Turbomeca turboprop/turboshaft engines should be 5.771. It is incorrectly given as 6.771.
Engine manufacturers are ready to benefit from the hot market for new business aircraft and helicopters in the coming decades. In addition to established manufacturers–General Electric, Honeywell, Pratt & Whitney Canada, Rolls-Royce, Turbomeca and Williams–several new OEMs will be introducing their own models to the market.
Cabin environment has been a major element of the completion process in the past couple of years, and it promises to become more so as concerns about air quality and drinking water grow.
“It caught my eye becauseit was…different,” said Brad Brooks, a customer service agent. That difference was an angleof ascent more than 45 degrees– other than a brief correction so violent that the tail pitched over the nose. “I’ve never seen that before,” said Brooks.
The so-called “father of very light jets,” Eclipse CEO and president Vern Raburn, knows this new class of small jets wouldn’t even be possible without suitable engines from Pratt & Whitney Canada, Williams International and GE-Honda Aerospace. Simply, these lighter, more efficient, lower-output turbofans have opened the door to new possibilities for jet aircraft designers.
