On January 14, 2010, at 1440 Pacific standard time, a Ercoupe 415-D, N2332H, experienced a loss of engine power after takeoff and landed in a field off the end of runway 36R at Napa County Airport, Napa, California. The commercial pilot operated the airplane under the provisions of Title 14 Code of Federal Regulations, Part 91. The pilot was uninjured and the airplane was substantially damaged. Visual meteorological conditions prevailed, and a flight plan had not been filed.
The pilot reported to the Safety Board investigator that both wing fuel tanks were full and the engine run up was normal. Almost immediately after takeoff the engine began to lose power, surged two times, then lost all power. The pilot landed in an open field off the end of the runway. During the landing the nose wheel sank into the soft ground and collapsed.
