Textron Lycoming O-320-D2A engine, in a new factory in the Netherlands. Certification of the Eaglet was expected by late that year, with the aircraft having a price of $120,000. In early 1999, Euro-ENAER was blaming poor weather and difficulties with the

Euro-ENAER finally managed to certify the Eaglet in 1992, but the company announced it needed additional funding to start production. These efforts failed, however, and Euro-ENAER was declared bankrupt later that year.
