NTSB narrative
The pilot reported that during a pleasure flight over a lake, about 700 ft above ground level, the engine started to shake and subsequently lost all power. The pilot attempted to restart the engine by turning the auxiliary fuel pump on, and he dove the airplane toward the water so that the windmilling propeller would help to restart the engine. The engine started, but the pilot estimated that it was only producing about 50% power. The pilot thought that he might be able to maintain or gain some altitude to reach a nearby runway; however, during the climb, the engine lost all power again. The pilot then initiated a forced landing to the lake. Witnesses around the lake reported seeing the airplane flying at low altitude. One witness stated that the engine sounded normal but that the airplane was flying erratically. Another witness saw the airplane about 40 ft above the water. He did not hear any unusual noises emanating from the engine. The airplane and engine remained submerged in the lake for about 3 weeks before recovery. The right wing was not recovered. Cursory examination of the engine revealed continuity to the accessory drive when the propeller was rotated by hand; however, the examination was insufficient to determine whether or for what reason a loss of engine power may have occurred.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
