Probable cause

An evasive maneuver during the landing flare to avoid deer on the runway, which resulted in a collision with trees and terrain during a go-around. Contributing to the accident was the lack of an airport perimeter fence.

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 solo student pilot reported that during a day visual meteorological condition flight, in the landing flare he saw a deer where he intended to touch down. He further reported that he banked to the right and applied power to go-around, but during the turn to the right he was unable to clear a line of trees in his flight path. The student pilot reported that the landing gear "scraped" one line of trees, and in order to avoid a thicker line of trees ahead, he forced the airplane down into a marsh area. The fuselage and both wings sustained substantial damage. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. During a postaccident interview with an airport representative, he reported that the airport does not a have a perimeter fence. The Federal Aviation Administration Chart Supplement airport page for the accident airport in part states: "Deer and birds on and invof [in the vicinity of] arpt."
