BBA Aviation-owned engine repair and overhaul company Dallas Airmotive plans to open a regional turbine center next month at the Washington County Airport just south of Pittsburgh. The 5,300-sq-ft facility initially will provide hot-section inspection services for Pratt & Whitney Canada PT6A turboprops and JT15D turbofans, as well as fan repairs on JT15Ds and power-section repair on PT6As.

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.

AvAero, a maker of Learjet hush kits, has received an STC for a fuel-saving aerodynamic modification of the Boeing 737-200/300. The company claims the mod will decrease the twinjet’s fuel burn by an average of 4 percent, equating to about a 230-pph fuel-burn reduction. By repositioning the trailing-edge flaps, AvAero said it increases aft wing camber, which lets the airfoil generate the same lift at a lower angle of attack.

Pratt & Whitney Canada’s new PW535E turbofan engine for the Embraer Phenom 300 has reached its full takeoff thrust of 3,360 pounds at the company’s Longueuil, Quebec test facility. Embraer chose the PW535E turbofan in May 2005 to power the Phenom 300.

The FAA has issued an airworthiness directive (AD) for the Eurocopter AS 350B/BA/B1/B2/B3/D and AS 355E Squirrel light helicopters, requiring replacement of the hydraulic fluid at a specified interval when operating in cold weather. The amendment is prompted by reports of ice forming due to condensation in some parts of the hydraulic system.

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.
