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 the landing roll on dry grass, the brakes “locked up” and “over we went.” The airplane came to rest inverted. The airplane sustained substantial damage to the left-wing lift strut. The pilot reported to the Federal Aviation Administration after the accident that the brakes worked better than he expected, and there were no preimpact mechanical malfunctions or failures with the brakes and that both wheels spun freely. A postaccident examination of the accident site showed no signs of disturbed terrain prior to the location of where the airplane came to rest inverted.
