Event Details
During the takeoff from a grass/turf runway, the pilot-in-command did not ensure that the propeller control lever remained in the full forward position throughout the entire takeoff sequence. As a consequence, the aircraft did not lift off the ground at a point where it would have under normal conditions. When it became apparent that the aircraft was not performing as expected, the pilot did not abort the takeoff. The aircraft lifted off late, collided with some trees and a fence, and then settled back onto the terrain. Subsequently, all three landing gear collapsed.
Investigation Findings
Examination revealed no indications of any malfunction of an aircraft system, nor any evidence that the engine was incapable of producing full power. The pilot-in-command did not use a checklist during his pre-takeoff and takeoff activities.
Probable Cause
The probable cause of the accident was the pilot-in-command's failure to ensure that the propeller control lever remained in the full forward position during the entire takeoff sequence, and his failure to abort the takeoff when it became clear that the aircraft was not performing as it should.
