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 of the tailwheel-equipped airplane reported that, during the landing roll, the airplane encountered a strong tailwind gust, which caused the airplane to roll at a faster than normal speed. Due to obstacles at the end of the runway, the pilot applied harder brake pressure. The nose dipped down, and the airplane nosed over and came to rest inverted. The airplane sustained substantial damage to the rudder and vertical stabilizer.
