At approximately 08:00 Pacific time, a Cessna 172 struck trees during low-level maneuvering about seven miles northeast of Conconully. The pilot and his passenger both received minor injuries. The Canadian pilot said he took off for a local sightseeing flight and, once airborne, decided to cross the border in order to show his passenger some of the terrain in northern Washington. At the time of the accident, he was heading back toward Canada while flying very low over the trees. He said he encountered a downdraft that made the aircraft sink and one wing collided with a tree. The aircraft then cartwheeled into the forest.
