Analysis

During the initial right climbing turn after takeoff from a private grass strip, the pilot noticed an engine RPM drop of approximately 100. The drop did not occur during cruise. The pilot reported that he made one spray pass and during the turning maneuver the airplane would not maintain altitude and the engine did not produce full power. The airplane impacted trees and terrain. Post crash fire destroyed the airplane.
