Probable cause

The student pilot's maneuver to the left to avoid striking birds during takeoff and his subsequent loss of directional control after aborting the takeoff and landing on soft, muddy grass adjacent to the runway during, which resulted in a nose-over.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The student pilot reported that, during takeoff, a flock of birds crossed the runway from the right. He tried to climb and turn the airplane to the left to avoid striking the birds, but some of the birds continued in front of the airplane. The airplane drifted beyond the left side of the runway about 10 to 15 ft above ground level. He aborted the takeoff, landed on the soft grass adjacent to the runway, and the airplane nosed over. The student added that, "the grass was so muddy that [it was] very hard to control the plane," and "too much friction made my airplane flip over." The airplane sustained substantial damage to the right wing. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
