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 stated that upon touchdown on the runway, the tailwheel-equipped airplane drifted to the left. The pilot applied right rudder to correct, but the airplane continued to travel to the left and departed the left side of the runway. The airplane contacted a ditch and nosed over and came to rest inverted, resulting in substantial damage to the vertical stabilizer and left wing. Postaccident examination revealed that the left main landing gear leg had collapsed and exhibited severe corrosion and evidence of a preexisting crack. The pilot also reported that the main gear strut failed because of cracks and corrosion.

Factual narrative

The pilot stated that he was landing to refuel during a pleasure flight. He reported that after touchdown on the runway, the tailwheel-equipped airplane began drifting to the left. The pilot applied right rudder to correct, but the airplane continued to travel to the left and departed the left side of the runway. The airplane contacted a ditch and nosed over coming to rest inverted, resulting in substantial damage to the vertical stabilizer and left wing. Postaccident examination by a Federal Aviation Administration inspector revealed that the left main landing gear leg had collapsed and exhibited severe corrosion and evidence of a preexisting crack.
