Stage III Technologies on February 8 ceased operations pending further funding, leaving just one company–Miami-based Quiet Technology Aerospace–currently providing hush kits for the Gulfstream II and III. Stage III’s hush kit
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.
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.
