Blue Mountain Avionics (BMA), a Copperhill, Tenn.-based manufacturer of electronics for the experimental and light sport aircraft market, has ceased production, citing the lagging economy, according to an announcement on the company's Website. "Well, it's been fun. We developed a whole new class of machine, started an industry, dominated it, and are now leaving it. BMA will be ceasing production and spinning down," according to a notice on the site. "We'll still be around to service, support and assist as time permits, homebuilders helping other homebuilders, but BMA is essentially closed. ... There is some hope (and a fond desire) that we may return to full production when the economy recovers. ... We are actively seeking someone to buy the code and continue development." Blue Mountain pioneered synthetic vision systems (SVS) and electronic flight instrument systems (EFIS) in the late 1990s.
