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 pilot reported that, during landing, on short final, he decided to go around. He added that, during the go-around, the airplane "developed a severe vibration," so he made a precautionary landing with the gear retracted. The airplane slid, exited the runway, and impacted terrain. The airplane sustained substantial damage to the external longerons on the lower fuselage and engine mounts. A Federal Aviation Administration inspector reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot reported that, during landing, on short final, he decided to go around. During the go-around, the airplane "developed a severe vibration" so he made a precautionary landing on runway 26 with the gear retracted. The airplane slid, exited the runway and impacted terrain. The inspector further reported that the airplane sustained substantial damage to the external longerons on the lower fuselage and engine mounts. The inspector added that, after his examination, he determined there were no mechanical malfunctions or failures to the airframe or engine that would have precluded normal operation.
