In April 2008 Adam Aircraft was purchased from bankruptcy by AAI Acquisition Inc who have indicated their intention to continue with certification of the aircraft. Industrial Investments, the Russian company that purchased Adam Aircraft, restarted work on the A700 and in May 2008 had 60 employees back at work. Industrial Investments reportedly ordered 75 A700s prior to Adam Aircraft's bankruptcy. AAI had initially intended to certify the A700 in the first quarter of 2010, but citing the

In April 2011 Triton Aerospace, the new holder of the type certificate, indicated that they would concentrate on the A500 and had no plans to continue development of the A700, even though they had two disassembled examples.

Design

As with the earlier-designed A500 piston-engined model, the A700 featured a straight tapered wing, a central
