Air Wisconsin

Swearingen SA226 Metro II

The airplane departed Appleton, Wisconsin, at 1245LT on a regular schedule service (ZW965) to Lincoln, Nebraska, with an intermediate stop in Minneapolis. En route, while cruising at 12,000 feet, the crew encountered moderate turbulences and precipitation and was cleared to descend to 8,000 feet then later at 6,000 feet. As turbulences were getting worse, the crew was later cleared to descend to 4,000 feet and finally 3,000 feet. While descending to 6,000 feet, massive water ingestion caused both engines to lose power simultaneously. Both engines were restarted but the Metro couldn't recover and struck a muddy field in a slight nose down, right wing-down attitude. The aircraft bounced and hit the ground 288 feet further on. The plane skidded 1,022 feet before coming to rest inverted. There was no fire. Two passengers were seriously injured while 13 other occupants were killed.

De Havilland DHC-6 Twin Otter

Following a uneventful flight from Sheboygan, the crew started the descent to Appleton Airport in relative good weather conditions when, at an altitude of 2,500 feet, the Twin Otter collided with a North Central Airlines Convair CV-580 registered N90858. En route from Green Bay to Oshkosh, the Convair was carrying two passengers and three crew members. At the time of the accident, both airplanes were flying under VFR in an uncontrolled airspace. Following the collision, both aircraft crashed into Lake Winnebago, some five miles southeast of Appleton Airport. Debris were found floating on water, both airplanes were totally destroyed and all 13 occupants were killed.
