FAA Approves Learjet 20 Series Noise Suppressor

FAA has issued a Supplemental Type Certificate (STC) for a Stage 3 noise suppression device for Learjet 20 series aircraft. 
The noise suppressor, produced by Butler National Corp., is an engine-mounted device designed to allow Learjet 20 series family aircraft to comply with Stage 3 noise restrictions, which take effect in December 2015. 

The FAA Modernization and Reform Act of 2012 implemented stage 3 noise suppression restrictions on a number of aircraft models, such as the Airbus A380, Boeing 747-8, and Bombardier Challenger 601.
