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.
