Hushkits Are Still Available for Some Stage 2 Jet Types
In its description of a new rule outlining the upcoming ban on jets that don’t meet Stage 2 noise standards, the FAA incorrectly stated that hushkits are available only for Gulfstream IIs and IIIs.
The rule stems from the FAA Modernization and Reform Act of 2012 and prohibits airplanes with a maximum weight of 75,000 pounds or less from operating within the contiguous U.S. after Dec. 31, 2015, unless they meet Stage 3 noise levels. The rule affects 599 airplanes, according to the FAA, and only those that can be modified with hushkits will be able to continue to fly.
Hushkits are available for GE CF700-powered Falcon 20s and the CF700-powered Sabre 80, and these are available from Kalitta Turbines, which bought the Noise Reduction Engineering (NRE) hushkit business from GE last year. The NRE hushkit for the CF700 sells for $170,000, according to Kalitta, and plenty of kits are available.
In addition, Butler National is near completing an STC for a Learjet 20-series hushkit, which it expects will be available this fall. Pricing hasn’t been set yet, according to the company.
Stage 3 hushkits are currently available for the Gulfstream II/III, from both Hubbard Aviation Technologies ($1 million+) and Quiet Technology Aerospace ($800,000).
