Aircraft involved
Probable cause & findings
The student pilot’s improper landing flare, which resulted in a bounced landing and subsequent loss of directional control and runway excursion during the aborted landing. Contributing to the improper landing flare was the student’s distraction by a deer running across the runway.
Factual narrative
The solo student pilot reported that he was practicing a stop and go landing on the asphalt runway. He recalled that the downwind leg of the approach pattern, headed into a bright sunset. On short final, "a medium sized, reddish brown animal ran across the runway near the numbers from right to left." The pilot over flew the animal and the airplane bounced upon touchdown. He applied full power to abort the landing, but the airplane veered left and exited the left side of the runway. About 40-feet from the runway, the airplane encountered soft soil and nosed over. During a conversation with the National Transportation Safety Board Investigator-in-charge, the student pilot stated that he may have become fixated on the animal during the approach. He could not recall whether he manipulated the yoke to avoid the animal. The airplane sustained substantial damage to the left-wing strut. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
