Incident: Baie-de-Port on the George River, Nouveau-Québec. 58.32N/65.55W 02/03-Oct-1973. The archive record is in French however the translation indicates that while at anchor a violent storm blew up at 23:30 hrs. The Otter was wrecked in the storm and sank. A salvage attempt proved impossible. The file quotes Ghislain Arsenault as uninjured. It is not stated but was he trying to save the aircraft from the storm? We may never know. A third party report quotes that it had crash landed in the Bay but perhaps unlikely in view of the quoted time. Maybe something lost in translation.
