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

After the airplane touched down, the pilot noticed two deer on the left side of the runway. One deer ran across the runway and was struck by the airplane’s left wing tip. The impact caused the airplane to veer off the left side of the runway onto the grass. The pilot raised the flaps, applied right brake/rudder and full power in an attempt to go around. The airplane lifted off momentarily and then struck a runway light. The pilot abandoned the go-around attempt. The airplane traveled across the runway and stopped in an open field. Both of the wings sustained leading edge damage, the nose gear was sheared off, and the lower engine cowling was crushed. The underside of the fuselage and the right horizontal stabilizer were also substantially damaged. The pilot reported no preimpact anomalies with the airplane.

Factual narrative

During landing touchdown the pilot noticed two deer to the left of the runway. One deer ran across the runway and was struck by the airplane’s left wing tip. The impact caused the airplane to veer to the left off the runway and onto the grass median. The pilot raised the flaps, applied right brake/rudder and full power in an attempt to go-around. The airplane lifted off momentarily, and then struck a runway light. The pilot abandoned the go-around attempt. The airplane traveled across the runway into an open bean field and stopped. Both wings sustained leading edge damage, the nose gear was sheared off, and the lower engine cowling was crushed. The underside of the fuselage and the right horizontal stabilizer were also substantially damaged. The pilot reported no preimpact anomalies with the airplane.
