France-based engine manufacturer Snecma has reported “positive results” for the first 35 ground test hours of its Silvercrest core engine. In an unusual move, the company has begun the test program without announcing a launch application for the new turbofan, which is targeted for applications on future super-midsize to large business jets. The core engine achieved “all the expected performance objectives” for these combustion trials.
CESSNA CARAVAN 208B, ROCKFORD, ILL., DEC. 17, 2002–Caravan N277PM crashed on a night ILS approach to Runway 7 at the Greater Rockford Airport (RFD) following a loss of control. The pilot was killed and the airplane was destroyed. The NTSB determined that the probable cause of the accident was the pilot’s failure to maintain control of the airplane during the approach.
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.
Reno, Nev.-based Aerion on Sunday announced at the Dubai Air Show that it is now accepting letters of intent for a “limited number” of early delivery positions for its 12-seat supersonic business jet (SSBJ). “Market demand has driven our decision to begin accepting deposits,” said company vice chairman Brian Barents.
The debate about the design of future commercial aircraft engines broadened this year as concerns mounted over the effect aircraft engines may be having on global warming, while the cost of aviation fuel rocketed and noise became ever more of an issue.
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.
Miami-based Quiet Technologies Aerospace in late January received FAA approval of its Stage 3 translating-ejector hush kit for Gulfstream IIs, IIBs and IIIs.
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.
