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

According to the pilot, the airplane was on final approach with the runway lights and airplane landing lights illuminated. During the landing flare, he heard a "bang" from the right side of the airplane. As the airplane continued on the landing rollout, the right wing settled onto the ground. The airplane veered to the right and came to rest on the edge of the runway surface. A postaccident examination of the airplane revealed that the right main landing gear was separated, which resulted in substantial damage to the right wing spar. The separated right main landing gear was located on the runway adjacent to a dead deer. The pilot reported that there were no preimpact mechanical anomalies with the airplane prior to it colliding with the deer.
