AceAir ceased operations in July 2004.
I understand that the Aeriks 200 had completed all of its flight tests and
was meeting most of its perfomance goals, but Diamond Engines, who had
bought manufacturing rights to the GiAe-110R rotary engine that the Aeriks
200 was designed around, pulled the plug on engine production. This
effectively killed the design and the company.
Unfortunately, although the Aeriks 200 was an exquisitely designed and
built aircraft, at $60K (2003) it was expensive. The recent runup of the
Euro against the dollar (which will likely persist for some years) would
have made it financially unviable in the US market.
A lot of great European VLA designs that were planned to be introduced
into the US market under the Sport Pilot category have likewise been
sidelined.
