Jet Aviation facilities in Geneva, Singapore, Teterboro, N.J., and West Palm Beach, Fla., have been appointed as authorized installation centers for Quiet Technology Aerospace’s hush kits in the Gulfstream II, IIB and III. The hush kits lower the aircraft’s noise signature below Stage 3 limits, weigh 234 pounds and require no modifications to the thrust reversers.
BOMBARDIER LEARJET 25C, LEXINGTON, KY., AUG. 30, 2002–The captain’s addition of forward thrust during the landing rollout, resulting in a lack of braking effectiveness, was listed by the NTSB as the cause of a runway overrun accident by Learjet 25C N45CP. A factor was the captain’s inability to deploy the thrust reversers for undetermined reasons.
Really Quiet has doubled the warranty on its Stage 3 hush kit and thrust-reverser system for the Gulfstream II. The new warranty is two years, 1,000 hours or 500 cycles, whichever comes first. Really Quiet of Reston, Va., was the first of two companies to receive an STC for installation of hush kits on Spey-powered Gulfstreams.
The NTSB determined Tuesday that the probable cause of the Dec. 5, 2005 landing overrun of a Southwest Airlines Boeing 737 at Chicago Midway Airport was the pilots' failure to use reverse thrust to slow the airplane after landing. This occurred because the pilots' lack of experience with the airplane's autobrake system distracted them from using the thrust reversers, the Safety Board said.
While three companies are competing to market FAR Part 36 Stage 3 hush kits for the Gulfstream II, IIB and III, two–Really Quiet and Stage III Technologies–have been developing their respective systems much longer than either originally planned. Really Quiet could very well be the first to receive FAA certification, which is expected this month.
Bombardier CL600-2B19 CRJ, Lake Michigan, Mich., April 7, 2007–The Mesa Airlines CRJ was substantially damaged when the thrust reverser translating cowling broke off the left engine during cruise and struck the horizontal and vertical stabilizers. The captain told the NTSB that at 16,000 feet msl, about 35 miles west of its departure airport, Grand Rapids Gerald R.
Nordam Group has elected Industry veteran Jonathan “Jack” Schofield to its board of directors. Schofield spent 38 years in the aviation business, previously serving as president of United Technologies Corp. and vice president international of Pratt & Whitney’s Commercial and Military Engine Divisions. In 2001 he retired from his position as chairman and CEO of Airbus North America Holdings.
Manufacturers of nacelles and thrust reversers have no less interest in introducing new technology to their designs than do the suppliers of the engines inside them.
Stage III Technologies, which received an STC two years ago this month for its hush kit for Gulfstream IIs and IIIs, plans to have its long-awaited first installation under way in August at Western Jet in Van Nuys, Calif. The kit, which pairs a mixer nozzle with an ejector shroud, yields a 50-percent reduction in noise, according to the company. A thrust reverser that the company says is good for 10,000 cycles is also included.
DASSAULT FALCON 20C, PUEBLO, COLO., JAN. 21, 2004–While landing on Runway 8 at Pueblo Memorial Airport (PUB) at 12:45 a.m., the Falcon twinjet veered off the runway. A wing became stuck in the snow and the right landing gear collapsed. There were no injuries, but the aircraft was substantially damaged.
