Butler National is nearing completion of an STC for a Learjet 20-series Stage 3 noise suppression device. The aircraft is subject to the FAA Modernization and Reform Act of 2012, which includes provisions that ban its operation in the U.S. after Dec. 31, 2015 for not meeting current FAA Stage 3 noise level requirements. Installation of the Avcon Noise Suppressor should allow continued use of the airplanes in 2016 and beyond.Butler projects installations of the Avcon Noise Suppressor STC will begin this fall.

Avcon is “nearing completion” of its STC project for a Learjet 20-series Stage 3 noise suppression device. Under the FAA Modernization and Reform Act of 2012, aircraft that do not meet Stage 3 noise level requirements–a category that includes unmodified 20-series Learjets–cannot be operated in the U.S. after Dec. 31, 2015. Installation of the Avcon noise suppressor on 20-series Learjets should allow continued use of the CJ610 turbojet-powered airplanes beyond that date, the company said. Installations of the STC’d suppressors are expected to begin in the fall.
