THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING WAS A FACTOR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - Ditching, landing - roll - terrain condition - water - terrain condition - none suitable (contributing factor) ## Analysis While in cruise flight at 1,700 feet mean sea level over a lake, the airplane's engine lost total power. The pilot was unable to restart the engine and was forced to ditch the airplane. The pilot stated that the shore of the lake was heavily treed and he did not think it would be safe to attempt a landing there. Post accident examination of the airframe did not reveal any anomalies. Fuel was present in the fuel tanks and throughout the fuel system. The engine was examined and no anomalies were found. ## Factual narrative On June 19, 1994, at 1641 eastern daylight time, a Classic Aircraft, WACO YMF5, N5YM, lost total engine power while in cruise flight at 1,700 feet mean sea level over Lake Erie near Put-in-Bay, Ohio. The pilot ditched the airplane. The pilot received minor injuries and the two passengers were not injured. The airplane was substantially damaged. Visual meteorological conditions prevailed at the time of the accident. The local sightseeing flight was operated under 14 CFR Part 91. The pilot reported that at 1,700 feet mean sea level, and about 1,500 feet from the shore, the airplane's engine lost total power. The pilot stated that he tried to restart the engine to no avail. He stated he elected to ditch the airplane instead of land on the heavily treed shore. The pilot and passengers exited the airplane while it was still afloat and were rescued by nearby boaters. The airplane sank to the bottom of the lake. The airplane was removed from the lake on June 20, 1994, and examined. The examination did not reveal any airframe anomalies. Fuel was present in each fuel tank and found throughout the fuel system. Under the supervision of a Federal Aviation Administration Safety Inspector, the engine was examined by a certified mechanic at General Aviation Incorporated located in Lansing, Michigan. No anomalies were noted. Further, the engine and its accessories were sent to the engine manufacturer, Jacobs Service Company, located in Scottsdale, Arizona, for a teardown inspection. The inspection did not reveal any anomalies. (See attached engine inspection reports for further details.) ## Aircraft - Registration: [N5YM](https://openairdocs.org/aircraft/N5YM), registered now, S/N F5036, built 1992 (OpenAirDocs) - Reported make and model: Classic Aircraft Corp.
