QTA bundles hush kit, RVSM
Making jet aircraft acceptably quiet can be a dirty job.

Making jet aircraft acceptably quiet can be a dirty job. Owners don’t want to spend the money, engine makers don’t want to compromise their products’ efficiencies and airport neighbors are rarely happy with the results.

Maintenance and modification shops, however, don’t mind the trouble. Business Jet Technology got into the hush-kit business by investing in a program three years ago with Quiet Technology Aerospace (QTA) to develop and certify a silencing system for the Spey-powered Gulfstream II and III. Founded in 1984, Quiet Technology lays claim to being the world’s oldest hush-kit designer and manufacturer. It holds eight separate STCs for large commercial and military transports and corporate jets.
