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 he had completed a normal landing, and during the landing roll, he heard a "pop noise." He said that the nose veered right, and he applied left rudder, but the right wing dropped and the right main landing gear collapsed. The airplane sustained substantial damage. A postaccident examination of the separated landing gear strut revealed that the interior of the strut exhibited a rust color consistent with oxidation. The separation was consistent with overload.
