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, following a precautionary shutdown of the No. 2 engine, he diverted to an alternate airport that was closer than the original destination. During the landing in tailwind conditions, the airplane touched down "a little fast." The pilot added that, as the brakes faded from continuous use, the airplane was unable to stop, and it overran the end of the runway, which resulted in substantial damage to the fuselage. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot reported that following a precautionary shutdown of the number 2 engine, he diverted to an alternate airport that was closer than the original destination. During the landing in tailwind conditions, the airplane touched down "a little fast." The pilot added that, as the brakes faded from continuous use, the airplane was unable to stop and overran the end of the runway, which resulted in substantial damage to the fuselage. The pilot reported that there were no mechanical malfunctions or anomalies that would have precluded an uneventful single engine landing.
