Certification Testing of GII Hush Kit Set To Begin
Quiet Technology of Miami last month expected to begin flying a Gulfstream II equipped with the company’s first FAA-conforming Stage 3 hush kit. The flight-test program is expected to be wrapped up this month and an STC is expected late next month or in early August. “The hush kit adds about 220 pounds, with no reduction in cruise speed,” Quiet Technology told AIN. “We expect the fuel burn of hush-kitted GIIs to increase by about 3- to 4 percent over non-hush-kitted GIIs.” Price for the kit is $1.5 million, and the company said it has so far received deposits from customers for eight kits. Really Quiet of Mojave, Calif., received an STC for its GII/GIII Stage 3 hush kit in January.
