Stage III Technologies Halts Operations

February 27, 2008, 5:33 AM

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
was FAA certified in 2005 for the Gulfstream II, IIB and III, and the first four installations, priced at $1.1 million, were scheduled for this March, July, August and September. The Stage III hush kit included a 10-lobe mixer nozzle coupled with an acoustically lined ejector and new cascade-style thrust reversers replacing the original clamshells. Stage III employed 10 people and its assets include nearly one
complete hush kit, the FAA supplemental type certificate and three patents, according to an industry source.
