[1] Between May 2005 and January 2007 SAI manufactured the Symphony SA-160 aircraft for the personal use, touring and flight training market.

[2] SAI was started in September 2003 as the North American production arm of Ostmecklenburgische Flugzeugbau GmbH, (East Mecklenburg Aircraft Works Limited).

[1] Realizing that the bulk of the market for this aircraft was in North America Stinnes set up a production facility in Trois-Rivières with financial help from the Government of Quebec.

[1] An agreement was signed between OMF Flugzeugwerk and Symphony Aircraft to produce the design on two production lines in North America and Europe.

[4] CEO Paul Costanzo indicated that factors involved in this situation included the dramatic fall in value of the US dollar against the Canadian dollar between 2003–2006, start-up and product improvement costs that were greater than expected and especially a venture capital environment in the Province of Quebec that Costanzo described as "dismal".

He stated at the time, "We have simply been unable to attract sufficient capital to allow us to effectively exploit the obvious opportunity that we have with the SA-160, let alone fund our planned development of a diesel two-place and a four-place product."

On January 22, 2007, following the withdrawal of its lead investor three days previously, Symphony Aircraft declared bankruptcy, closed its doors and laid off its entire workforce.
