Two small aviation companies, one from Cornwall, Vt., and the other Colorado, have agreed to settle a lawsuit and part ways after their joint effort to fix a commercial, European-built Airbus A-300 cargo plane shot down in Iraq fizzled. Islamic terrorists brought down the DHL cargo jet with a shoulder-fired missile in 2003. Papers on file at U.S. District Court in Burlington show that Cornwall-based Chrison Aerospace and Pacific Aeromotive of Erie, Colo., have agreed to split up airplanes, tools, parts and other assets scattered in five countries. They'll split about $57,000 in debt. However, news reports indicate that Pacific Aeromotive plans to complete repairs of the jet. We're going to fly that plane out of Baghdad and sell it," Pacific attorney David Pocius of Burlington told reporters last week. Once restored, the plane can be sold for $7 million to $10 million. John Jack Downey has been president of Chrison since it started in 1999. A native of Burlington, he holds an FAA certificates and 10,000 flight hours. He has been involved in the aerospace industry since 1970. Chrison corporate office is located at 48 Tulley Rd. in Cornwall. Another local firm, Brown's Welding in Bristol, worked on steel wing components for the jet repair project.
