Emergency AD 2003-08-52 was issued last month for the GE CT7-9B turboprop in response to 12 compressor-stall events in Saab 340Bs over a six-month period. The stalls occurred when pilots throttled back from takeoff power to climb power. Nine of the events involved engines that had the compressor variable geometry (VG) rigged to N1, one of two allowable rigging options that affords slightly higher performance at the expense of stall margin.
Despite having lost out to Rolls-Royce in the competition to power Dassault’s still-under-wraps super-midsize Falcon, Snecma is moving ahead with development its Silvercrest engine for business jets. The French manufacturer (Booth No. 824) is here exhibiting a full-size mockup of the 10,000-pound-thrust-class turbofan.
Snecma is progressing with its plans to develop a turbofan in the 10,000-pound-thrust class. Last October, the French manufacturer revealed plans to enter the business jet engine market. Design of the Silvercrest powerplant is well under way and the core should run later this year.
