Analysis

The plt was practicing aerial application maneuvers without chemicals onboard. During a turn, the plt reported that the engine lost power. The plt leveled the wings and lowered the nose to gain airspeed. The plt selected a landing site and after touchdown, the left main gear hit a small ridge and collapsed. A post accident engine teardown by the owner did not reveal any preimpact malfunctions/failures.
