With an established reputation in the field of on-board water treatment for aircraft, International Water-Guard of Burnaby, British Columbia, has launched a program to develop a components line that includes the “pumps, valves and heaters that make up a complete water system.” According to IWG president and CEO David Fox, “Distributed device control is the way of the future, [and] IWG will be able to provide both system components and controll

The efficiency of the gas turbine engines that power today’s commercial and military aircraft is approaching the highest level possible with current turbofans. But a totally new technology being pioneered by GE Aviation and researchers worldwide promises far simpler, more efficient engines that will extend aircraft range, cut fuel costs and reduce emissions.

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.

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.
