I'm considering having a Smoking Airplanes smoke system installed in my 7ECA. These require a field approval and my IA needs 2 to 3 sample Form 337's that have been approved for a 7-series in order to submit mine. I can find samples for the 8-series Super D, but not the 7-series. Would anyone in the Club have a sample they could share with me? Thanks!
