A factor associated with the accident was the ravine which the airplane contacted during the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - initial climb - fuel system,line - ice (cause) - aircraft preflight - inadequate, pilot in command (cause) - Forced landing, emergency landing after takeoff - On ground/water encounter with terrain/water, landing - flare/touchdown - terrain condition - ravine (contributing factor) ## Analysis The pilot reported that after takeoff at an altitude of 75 to 100 Feet above the ground a loss of engine power occurred. The airplane was landed in a snow covered field off the end of the runway where it contacted a ravine. An inspector from the Federal Aviation Administration examined the airplane and the inspector reported that ice was found in the fuel system, which resulted in the loss off engine power. The line leading to the fuel quick drains contained six inches of ice near the valve. The airplane had been kept outside. The left fuel tank filler cap, which was recessed, was found covered with ice. ## Factual narrative On January 19, 1999, at 1930 central standard time, a Cessna 150C, N1956Z, operated by a private pilot collided with a snowbank during a forced landing following a loss of engine power while taking off from the Morey Airport, Middleton, Wisconsin. The pilot was not injured. The airplane was substantially damaged. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The flight was originating at the time of the accident. The pilot reported that after takeoff at an altitude of 75 to 100 feet above the ground a loss of engine power occurred. The airplane was landed in a snow covered field off the end of the runway. The airplane contacted a ravine and came to rest approximately 80 feet off the end of the runway. The airplane was examined by an inspector from the Federal Aviation Administration Milwaukee, Wisconsin, Flight Standards District Office.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
