Descripción:
After departing the floatplane base on a company VFR flight plan, the Otter proceeded northwest along a salt water strait at a low altitude above water. Two miles Northwest of the airport the aircraft entered a snow squall and the pilot attempted a steep turn to reverse course. During the turn the aircraft impacted and sank in 167 feet deep water.
PROBABLE CAUSE: "The pilot's inadvertant flight into ifr conditions and the stall which occurred during the turn to reverse course. Contributing to the accident were the snow conditions encountered."
