In a study released today entitled “The Market for General Aviation/Utility Aircraft 2007-2016,” Forecast International said it anticipates a decline in corporate demand for twin turboprops in favor of the fractional ownership of turbofan-powered aircraft. Further, it expects this trend to accelerate as more sub-$4 million very light jets are delivered.

The FAA is accepting comments until August 16 on a proposed Airworthiness Directive that would affect as many as 3,572 TFE731-2 and -3 turbofans on U.S.-registered aircraft. If the measure is enacted, the engines’ low-pressure turbine stage 1 disks would have to be repetitively checked for fatigue cracks. An estimated 1,900 of those engines would require disk replacement under the proposed AD.

Dassault senior v-p for civil aircraft Olivier Villa has clarified that the unusually high thrust (two 10,000-pound engines) on the still-under-wraps super-midsize Falcon will be put to work for maximizing climb and cruise performance. There has been speculation about why the manufacturer asked Rolls-Royce to supply turbofans with significantly more thrust than the 7,000 pounds common in this market segment.
