Avcon Industries, a subsidiary of Butler National announced that on the opening day of NBAA 2013 it received a supplemental type certificate (STC) for its 2015 Stage 3-noise compliant hushkits for the Learjet 20 series, covering most of the 350 Learjet 20-series still in service. The STC does not include those with the unmodified straight-wing and Dee Howard XR-wing–those will need a separate STC, which the company expects to tackle at a later date. Avcon brought its flight-test aircraft to the NBAA 2013 static display at Henderson Executive Airport.
Avcon Industries received STC approval for its 2015 Stage 3-noise compliant hushkits for 20-series Learjets, the company announced this week at NBAA 2013. The STC covers most of the 350 Learjet 20 series still in service, but does not include those with the unmodified straight wing and Dee Howard XR-wing; these will need a separate STC, which the company plans to obtain at a later date. Avcon expects the first customer aircraft installation to be complete next month.
When it comes to unzipping the belly of a Beechcraft King Air to install a sophisticated camera system or modifying classic Learjets with modern radios and new hushkits, the team at Avcon Industries in Newton, Kan., knows exactly what it takes to get such a project done.
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.
The aircraft modification segment of Butler National’s wholly owned subsidiary Avcon (Booth No. C3004) is exhibiting at Heli-Expo for the first time. Avcon is armed with a novel concept design for a skid-mount portable system for Lidar system operations in rotorcraft. Avcon modifies business and cargo aircraft, both fixed-wing and rotorcraft, in Newton, Kansas, and provides many FAA-approved solutions to a variety of operators.
Prague, Czech Republic-based ABS Jets (Stand 775) has announced the creation of a joint venture with Vienna, Austria-based Avcon Jet to open an Embraer line maintenance station at Kiev Borispol airport in Ukraine. The agreement also covers warranty work. Both companies are Embraer sales representatives, and both operate Legacy 600s–five and four, respectively.
Business aircraft maintenance, modification and completions firm Stevens Aviation today delivered the first Lear4Ever–an upgraded Learjet 35–to Dr. Steve Bass in a ceremony at its Greenville, S.C. headquarters. For $2 million and six months of downtime, the Lear4Ever program provides “a series of upgrades, retrofits and modifications” intended to modernize and extend the useful life of 20- and 30-series Learjets.
After discovering last September that both companies were planning to launch their own RVSM certification programs for the Learjet 20 series, Avcon and Bizjet International decided that “rather than fight each other for the same market, we preferred to come to an agreement and cut the research and development costs in half.” According to Larry Franke, president of Avcon, each company will bear half the cost of development and certification, w
Just one year ago there were none. Now, four companies have suddenly announced their intention to develop an RVSM STC package for the Learjet 20 series to be available next year. All four companies propose to achieve the approval using the airplane’s original JET autopilot and estimate the price to be around $150,000.
