Analysis

As the student was recovering from a slip maneuver at about 1,500 ft power was applied. The eng initially produced about 2500 RPM, then decreased to about 2000 RPM. Application of carburetor heat did not have any effect of the eng RPM.RPM continued to decrease to about 1200 RPM. The CFI took control & attempted to land on a riverbed. During the approachthe right wing struck a powerline. The CFI was able to maintain control of the acft & landing was made on the soft, sandy riverbed. The nose wheel separated as it dug into the ground & the acft flipped over onto its back.
