What happened
According to the certified flight instructor (CFI), the student pilot initiated a nose-up pitch input prematurely during the takeoff roll. This action caused the aircraft to become airborne before reaching the recommended rotation speed or altitude. Once in the air, the aircraft remained within ground effect, preventing an adequate rate of climb. Recognizing the inability to gain sufficient altitude, the decision was made to abort the takeoff. During this aborted maneuver, the aircraft impacted a line of trees.
The investigation
Post-accident examination revealed that the student pilot lacked prior experience operating on grass runways. This inexperience likely contributed to the improper timing of the rotation maneuver. The premature lift-off resulted in an aerodynamic stall condition close to the ground, leaving insufficient energy or altitude to clear obstacles.
Findings
The primary factors leading to the accident were the student pilot's failure to maintain proper takeoff technique and the subsequent loss of control due to premature liftoff. The lack of experience with grass runway operations exacerbated the situation, as surface friction characteristics differ from paved surfaces, often requiring adjusted rotation timing.
Safety message
Pilots must ensure they are proficient in takeoff techniques for the specific runway surface type. Understanding ground effect and maintaining proper airspeed during the initial climb phase is critical to avoiding terrain collisions during aborted or failed takeoffs.
